If you’re new to lifting at Planet Fitness or just wondering about the equipment, a common question is about the weight of the bars. At most Planet Fitness locations, you won’t find standard free-weight barbells like those used in powerlifting or Olympic lifting on squat racks or benches. Instead, the primary bar available for exercises like squats and bench presses is part of a Smith machine. So, how much do Planet Fitness bars weigh? The bar on a Planet Fitness Smith machine typically weighs somewhere between 15 to 20 pounds. However, this weight can vary depending on the specific machine model and whether it’s counterbalanced. The common answer to “how much does a Smith machine bar weigh?” is usually around 15 to 45 pounds for standard gym models, but the Planet Fitness versions are often on the lighter side and frequently counterbalanced, making the felt weight even less, sometimes feeling as light as 6 to 10 pounds or even zero in some fully counterbalanced versions. So, when asking how heavy is a Smith machine bar at Planet Fitness, expect it to be significantly lighter than a traditional free-weight barbell.

Grasping the Planet Fitness Bar Setup
Planet Fitness gyms have a specific kind of equipment setup. They focus on a comfortable and easy-to-use environment. This means they often skip heavy free weights and powerlifting gear. You won’t usually see separate squat racks with loose barbells or dedicated bench press stations with 45-pound Olympic bars.
Instead, they mostly use machines. For exercises where you’d normally use a barbell, they use the Smith machine. The Smith machine is a weight machine that has a barbell fixed within steel rails. This setup allows only vertical or near-vertical movement.
What is a Smith Machine Bar?
A Smith machine bar is the long metal bar you load weight plates onto. It’s different from a standard barbell. A standard barbell is a free bar you lift off a rack and balance yourself. A Smith machine bar stays on its track. You can hook it onto catches along the track at different heights. This fixed path makes it feel more stable.
The Core Question: Planet Fitness Smith Machine Bar Weight
Okay, let’s get right to it. The main bar at Planet Fitness that people use for pressing and squatting is the Smith machine bar. What does it actually weigh?
Most sources and reports from gym-goers say the Planet Fitness Smith machine bar weight is usually in the range of 15 to 20 pounds.
This is much lighter than a standard barbell. A standard men’s Olympic barbell, used in many gyms for free weights, weighs 45 pounds (about 20 kg). A standard women’s Olympic barbell is 35 pounds (about 15 kg). Even a standard fixed-weight curl bar or triceps bar is often 20-50 pounds.
Why is the Weight Important?
Knowing the weight of the bar matters for a few reasons:
* Tracking Progress: If you add plates to the bar, you need to know the bar’s weight to know the total weight you are lifting.
* Starting Point: The bar’s weight is your starting weight for any exercise. You need to know this to plan your workout.
* Comparing to Free Weights: If you’re used to lifting a 45-pound free-weight bar, lifting a 15-pound Smith machine bar feels very different. It’s important to know the difference when you compare your strength.
The Counterbalancing Effect
This is where it gets a bit tricky, especially with Planet Fitness Smith machine bar weight. Many Smith machines, including those at Planet Fitness, use a counterbalance system.
How Counterbalancing Works
Imagine the bar has weights or a pulley system behind the scenes. This system pulls up on the bar just enough to offset some of its weight.
Think of a seesaw that is perfectly balanced even with someone on one side. That’s kind of what counterbalancing does for the bar.
What Counterbalancing Does to the Felt Weight
The actual physical weight of the bar (the weight you’d measure if you put it on a scale) might be 15-20 pounds. But because of the counterbalance, the weight you feel and have to lift might be much less.
- Some machines are partly counterbalanced. The 15-20 pound bar might feel like only 10 pounds or even 6-8 pounds.
- Some high-end machines are fully counterbalanced. This means the bar feels like it weighs almost zero pounds.
Most reports suggest Planet Fitness machines are at least partly counterbalanced. So, while the bar’s true weight is likely 15-20 pounds, the effective or felt weight is often much lower. This lower felt weight is why it’s common to see people lift weights on the Planet Fitness Smith machine that seem high, but part of that is because the starting weight (the bar) is very light or feels very light.
Smith Machine Bar Weight Variation
It’s important to know there can be Smith machine bar weight variation. Not all Smith machines weigh exactly the same. Even within different models made by the same company, there can be slight differences. The weight might be 15 pounds on one machine and 20 pounds on another in the same gym, though this much variation within the same brand in one gym is less common. More likely, if Planet Fitness uses different machine brands across its many locations, the bar weight could differ more notably between those locations.
- Brand Differences: Different companies make Smith machines. They use different materials and designs. This changes the bar’s actual weight.
- Counterbalance Differences: The amount of counterbalance can vary a lot between machines. This changes the felt weight even if the actual bar weight is similar.
- Machine Age/Maintenance: Over time, parts might wear. This usually doesn’t change the bar’s physical weight but could slightly affect how the counterbalance system works.
This is why getting an exact number for every Planet Fitness bar is hard. The 15-20 pound range for the actual bar weight is a very good estimate for their typical equipment. The felt weight is usually less due to counterbalancing.
Finding the Exact Weight at Your Gym
If you really want to know the precise weight of the Smith machine bar at your specific Planet Fitness:
- Look for Stickers: Sometimes, the weight is written on a sticker on the machine itself. Check the frame or near the bar hooks.
- Ask the Staff: The employees might know the weight of their equipment. Ask a trainer or the front desk staff.
- Weigh It (Carefully): This is tricky and usually not possible or allowed. You can’t just take the bar off the machine to weigh it. Some advanced machines might have a digital display, but this is rare at Planet Fitness.
For practical purposes, assuming the actual bar weight is 15-20 pounds and the felt weight is lower (maybe 6-10 lbs or even less due to counterbalance) is a safe bet for tracking your weights.
Comparing Smith Machine to Standard Barbells
To put the Planet Fitness Smith machine bar weight in perspective, let’s look at standard barbells you find in other types of gyms.
Standard Barbell Weight
A standard barbell weight often refers to the bars used for general lifting, not necessarily Olympic lifting rules, but heavier than lightweight bars.
* Often, these are 45 pounds (20 kg).
* Some gyms might have lighter standard bars, maybe 30 or 35 pounds, for certain exercises or users.
Olympic Barbell Weight
An Olympic barbell weight is a specific standard used in sports like weightlifting and powerlifting.
* Men’s Olympic bars weigh 20 kilograms (45 pounds). They are 2.2 meters long.
* Women’s Olympic bars weigh 15 kilograms (33 pounds). They are 2.01 meters long.
* These bars are made to high standards, can hold a lot of weight, and have rotating sleeves.
As you can see, the 15-20 pound (or lower felt weight) of a Planet Fitness Smith machine bar is significantly less than a 35 or 45-pound standard or Olympic barbell.
Average Barbell Weight in a Gym
What is the average barbell weight gym has? In a well-equipped gym with free weights, you’ll find a mix:
* Olympic Barbells (45 lbs, 35 lbs)
* Standard Barbells (maybe some fixed 45 lbs bars)
* Pre-weighted straight bars (often in increments like 10 lbs, 20 lbs, 30 lbs, up to 100+ lbs)
* EZ Curl Bars (often 15-30 lbs unloaded)
* Triceps Bars (often 20-30 lbs unloaded)
The “average” is hard to pin down, but the most common heavy bar you’ll see is the 45-pound Olympic or standard bar. Planet Fitness often only has the Smith machine (15-20 lbs actual, less felt), pre-weighted straight bars, and maybe EZ curl bars. This makes the average available bar weight at Planet Fitness much lower than in a free-weight focused gym.
Bar Weight for Specific Exercises at Planet Fitness
At Planet Fitness, the Smith machine is used for many exercises where you’d normally use a free barbell.
Planet Fitness Bench Press Bar
When you do bench press at Planet Fitness, you use the Smith machine. So, the Planet Fitness bench press bar is the Smith machine bar. Its weight is the same as discussed: 15-20 pounds actual weight, but feels less due to counterbalance. You lie on a bench positioned under the Smith machine bar.
Weight of Squat Bar at Planet Fitness
Similarly, if you do squats at Planet Fitness using a bar, you’ll use the Smith machine. There isn’t a separate weight of squat bar at Planet Fitness like a heavy 45-pound bar on a squat rack. The bar is the Smith machine bar, weighing 15-20 pounds (actual) and feeling lighter. You stand under the bar in the Smith machine.
It’s crucial to remember that performing squats or bench presses on a Smith machine is different from using free weights. The fixed path changes how your muscles work and how you need to balance. This means the weight you can lift might be different compared to free weights, even after accounting for the bar’s weight.
Why Planet Fitness Uses Smith Machines
Planet Fitness chooses equipment that fits its model: creating a comfortable gym for casual users and beginners.
* Safety: The Smith machine’s fixed path and safety catches can make some people feel safer, especially when lifting alone. If you can’t complete a rep, you can hook the bar onto the nearest safety catch. This reduces the risk of dropping the bar on yourself.
* Ease of Use: Beginners might find it easier to learn exercises like squats and bench presses on a Smith machine because they don’t have to worry about balancing the bar.
* Space: Smith machines are self-contained units.
* Target Audience: The focus is less on heavy powerlifting and more on general fitness and machine-based workouts.
However, it’s worth noting that some trainers argue Smith machines are not always safer or better. The fixed path can put unnatural stress on your joints if your body doesn’t move in a perfect straight line (and most people don’t). Free weights force you to use stabilizing muscles that aren’t worked as hard on a Smith machine.
Tracking Progress on the Smith Machine
Even with the counterbalanced bar, you can still track your progress.
* Record Total Weight: Write down the weight of the plates you add plus the bar’s weight (using the 15-20 lb actual weight or your best estimate of the felt weight, just be consistent). Example: 2 plates of 45 lbs on each side (90 lbs total) + 20 lb bar = 110 lbs total.
* Record Plates: Simpler approach: just record the plates. “Squats: 2 plates (45s) on Smith machine.” This is easier but doesn’t give the exact total weight.
* Focus on Reps: Improve by doing more reps with the same weight.
* Focus on Sets: Improve by doing more sets.
* Focus on Form: Improve by doing the exercise with better technique.
Knowing the bar weight helps you accurately measure the load and see if you’re getting stronger over time.
Smith Machine vs. Free Weight Bar Weight Recap
Let’s quickly look at the weights again:
| Bar Type | Typical Weight Range (Approximate) | Common Use | Found at Planet Fitness? |
|---|---|---|---|
| Planet Fitness Smith Machine Bar | 15 – 20 lbs (Actual Weight) | Squats, Bench Press, Rows, etc. (fixed path) | Yes |
| Planet Fitness Smith Machine Bar | 6 – 10 lbs or less (Felt Weight) | Due to counterbalance system | Yes |
| Standard Olympic Bar (Men’s) | 45 lbs (20 kg) | Olympic Lifts, Powerlifting, General Strength | Usually Not |
| Standard Olympic Bar (Women’s) | 33 lbs (15 kg) | Olympic Lifts, Powerlifting, General Strength | Usually Not |
| General “Standard” Barbell | Often 45 lbs, sometimes 30-35 lbs | General Strength, Powerlifting (vary by gym) | Usually Not |
| Pre-weighted Straight Bar | 10 lbs, 20 lbs, up to 100+ lbs | Curls, Triceps, Squats, Lunges (fixed weight) | Yes |
| EZ Curl Bar (unloaded) | 15 – 30 lbs | Biceps Curls, Triceps Extensions | Often Yes |
This table makes it clear that the average barbell weight gym might have a variety, but Planet Fitness largely focuses on the lighter Smith machine bar and fixed-weight options. The weight of squat bar at Planet Fitness and the Planet Fitness bench press bar both refer to this lighter Smith machine bar.
Deciphering the Lighter Weight’s Impact
A 15-20 pound bar that feels even lighter changes things:
* Lower Starting Point: This is great for absolute beginners who might find a 45-pound bar too heavy to even lift empty with good form.
* Easier to Add Weight: When you add a 45-pound plate, it’s a bigger jump compared to a 45-pound bar. With a lighter bar, adding a small 2.5 or 5-pound plate feels like a more significant percentage increase relative to the starting weight.
* Different Feel: The exercise feels different. You rely less on your small stabilizing muscles. This might be good for isolating large muscle groups, but less ideal for building overall strength and coordination needed for free weights.
Knowing the actual bar weight (15-20 lbs) is important for calculating the total load, but being aware of the lower felt weight due to counterbalancing helps explain why lifting certain weights on the Smith machine might feel easier than the math suggests compared to free weights.
How Heavy Is a Smith Machine Bar? Delving Deeper
Let’s really focus on “how heavy is a Smith machine bar”. We’ve established the Planet Fitness Smith machine bar weight is around 15-20 lbs actual, and less felt due to counterbalance.
General how much does a Smith machine bar weigh figures for other gyms range wider, sometimes from 15 lbs up to 45 lbs or even 50 lbs for older, non-counterbalanced models.
The Smith machine bar weight variation comes down to:
1. Material and Thickness: How much steel is in the bar?
2. Length: Longer bars weigh more.
3. Sleeve Type: The ends where plates go can differ.
4. Counterbalance System: This is the biggest factor affecting felt weight. A strong counterbalance makes a heavier bar feel very light. A machine with no counterbalance means the actual bar weight is the felt weight.
Planet Fitness likely chooses models with significant counterbalancing to keep the starting weight low and user-friendly, fitting their brand image.
Considering Other Bars at Planet Fitness
While the Smith machine bar is the main one people ask about for exercises like bench and squat, Planet Fitness also has other bars:
* Pre-weighted Straight Bars: These are fixed weight bars. You’ll find racks with bars clearly marked with weights like 10 lbs, 20 lbs, 30 lbs, up to 100 lbs or more. The weight includes the bar itself.
* EZ Curl Bars: These have a wavy shape for bicep curls and triceps extensions. Unloaded, they usually weigh between 15 and 30 pounds. Planet Fitness might have these as fixed-weight bars too, or ones you load plates onto.
* Accessory Machine Bars: Cable machines have various attachments, including straight bars and curl bars. The weight comes from the weight stack, not the bar itself (the bars are usually just a few pounds).
So, while the average barbell weight gym wide (including free weight gyms) leans towards 45 lbs as a common heavy bar, at Planet Fitness, the common heavy bar equivalent (the Smith machine) is much lighter, and the other bars are either fixed weight or lighter utility bars.
The Takeaway on Planet Fitness Bar Weights
For someone lifting at Planet Fitness, the most important thing to know is about the Smith machine bar.
* Actual Weight: Expect it to be around 15-20 pounds.
* Felt Weight: Expect it to feel significantly lighter, possibly 6-10 pounds or even less, because of counterbalancing.
* Not Standard Barbells: These are not the 45-pound barbells you’d find in a standard squat rack or bench press station in a free-weight gym.
* Other Bars: Planet Fitness has pre-weighted bars (weight is marked) and potentially light unloaded EZ curl bars.
When you see discussions about standard barbell weight or Olympic barbell weight, remember that Planet Fitness equipment is generally different. The Planet Fitness squat rack bar weight and Planet Fitness bench press bar both refer to the lighter, counterbalanced Smith machine bar. Knowing how much does a Smith machine bar weigh at your specific gym (or using the 15-20 lb estimate) and understanding the counterbalance is key to tracking your lifting accurately within that gym’s setup.
Using the Smith machine effectively means focusing on the movement path and engaging the correct muscles, despite the machine guiding the bar. Track your weight by adding the plates to the bar’s estimated actual weight. Don’t just compare your Smith machine numbers directly to someone else’s free-weight barbell numbers; they are different exercises with different loads and demands on the body.
FAQ: Common Questions About Planet Fitness Bar Weights
Here are answers to some often-asked questions about bar weights at Planet Fitness.
Q: How much does the bar weigh on the Smith machine at Planet Fitness?
A: The bar on a Planet Fitness Smith machine typically has an actual weight of 15 to 20 pounds. However, due to counterbalancing systems, the weight you feel and lift is often much less, potentially feeling as light as 6 to 10 pounds or even less.
Q: Is the Smith machine bar at Planet Fitness counterbalanced?
A: Yes, most Smith machines at Planet Fitness are counterbalanced. This system uses weights or pulleys to offset some of the bar’s actual weight, making it feel much lighter to lift.
Q: How much does a standard barbell weigh compared to the Planet Fitness Smith machine bar?
A: A standard men’s Olympic barbell weighs 45 pounds (about 20 kg). A standard women’s Olympic bar weighs 33 pounds (about 15 kg). The Planet Fitness Smith machine bar, at 15-20 pounds actual weight (and less felt), is significantly lighter than these standard free-weight barbells.
Q: Does Planet Fitness have standard 45-pound barbells?
A: Most Planet Fitness locations do not have separate squat racks or bench press stations with standard free-weight 45-pound barbells. The primary bar for these types of exercises is found on the Smith machine.
Q: How much do the pre-weighted straight bars weigh at Planet Fitness?
A: Planet Fitness gyms usually have racks of pre-weighted straight bars. The weight is clearly marked on the end of these bars, typically starting at 10 pounds and going up in increments (like 10, 20, 30, 40, 50 lbs, etc.).
Q: Can I use the Smith machine bar for all barbell exercises?
A: The Smith machine can be used for many exercises like squats, bench press, rows, and overhead press. However, the fixed path changes the exercise compared to using a free-weight barbell. Some exercises, like deadlifts from the floor, are not suitable or possible on a Smith machine.
Q: How do I know the exact weight of the bar at my specific Planet Fitness?
A: Look for a sticker or label on the Smith machine frame or bar. If you can’t find one, ask a staff member. Using the 15-20 pound estimate for actual weight is usually close enough for tracking purposes, but remember the felt weight is less due to counterbalance.
Q: Does the Smith machine bar weight vary between different Planet Fitness locations?
A: There can be slight Smith machine bar weight variation between locations if they use different models or brands of Smith machines. However, the typical range of 15-20 pounds actual weight and significant counterbalancing is standard for the chain.
Q: Is the weight of squat bar at Planet Fitness the same as the bench press bar?
A: Yes, at Planet Fitness, the bar used for squats (when done on the Smith machine) is the same bar used for bench press (when done on the Smith machine). It is the Smith machine bar itself.
Q: How does the counterbalance affect the weight I’m lifting?
A: The counterbalance system reduces the effective weight of the bar. If the bar weighs 20 pounds but the counterbalance provides 10 pounds of assistance, the felt weight you have to lift is only 10 pounds. This means the actual total weight lifted is the weight of the plates plus the bar’s felt weight, not its physical weight, which is why using the felt weight can sometimes be more practical for comparing performance on that machine. However, for consistency and comparing to the bar’s specification, using the 15-20 lb actual weight plus plates is common practice. Just be clear whether you are counting actual bar weight or estimated felt weight.
