You’ve seen the late-night infomercials. Chuck Norris and Christie Brinkley are grinning, gliding up and down those rails like it’s the easiest thing in the world. And for a lot of people, it is. That’s the problem. Eventually, the body weight resistance on a Total Gym—even at the steepest incline—just stops being enough to trigger new muscle growth. You’re doing 50 reps and barely breaking a sweat. You need more iron. Honestly, the total gym weight bar is the most underrated accessory in the entire ecosystem because it transforms a "toning" machine into a legitimate muscle-building tool.
But there’s a lot of confusion out there. People buy the bar, slap on some plates, and then wonder why the glide board feels clunky or, worse, why they hear a terrifying crack from the frame.
The Reality of the Total Gym Weight Bar
Basically, this is a steel rod that slides through the base of your glide board. It lets you add standard 1-inch plates to the machine. It’s not a complex piece of engineering, but using it correctly requires a bit of nuance. You can’t just stack 200 pounds on there and expect the cable system to hold up. Most official Total Gym bars are rated for about 90 to 100 pounds of additional weight (45 lbs per side).
Why does this matter? Because the physics of a slant board are different than a barbell bench press. When you add weight to the glide board, you’re increasing the mass you have to move against gravity, but you’re also increasing the friction on the rollers.
If you’ve got an older model like the 1400 or the XL, check your manual. Not every frame is built to handle the torque of a loaded weight bar. The Fit, GTS, and XLS models are usually the prime candidates for this upgrade. I’ve seen guys try to DIY a weight bar using a galvanized pipe from Home Depot. Don’t do that. The official bar has specific hitch pins to keep it from sliding out. If that bar shifts mid-set, the weight distribution goes wonky, and you’re looking at a bent frame or a broken floor.
Why Resistance Curves Change Everything
When you’re using just your body weight, the resistance is linear. You’re moving a percentage of your own mass. On a Total Gym XLS, at the highest setting, you’re moving roughly 62% of your body weight. For a 200-pound person, that’s about 124 pounds of resistance.
Add a total gym weight bar with two 25-pound plates. Suddenly, you’re moving 124 pounds plus the added 50 pounds (adjusted for the incline angle).
The math gets nerdy, but here is the gist:
- At lower levels, the weight bar adds less "effective" resistance.
- At the highest levels, the weight bar feels significantly heavier.
- The cables and pulleys now have to deal with increased tension, which means your form has to be tighter than ever.
I’ve talked to long-time users who swear that adding 20 pounds via the bar feels harder than adding 20 pounds of body fat. It’s because the weight is dead weight located directly over the rollers. It changes the center of gravity of the glide board. You’ll feel it in your lats during pull-ups and definitely in your quads during leg presses.
Common Mistakes with Plate Loading
Don't use Olympic plates. Just don't. The standard Total Gym weight bar is 1 inch in diameter. If you put 2-inch Olympic plates on it, they’re going to jiggle and clank. That instability is more than just annoying; it creates a pendulum effect that can wear out your rollers prematurely. Use "Standard" plates with the 1-inch hole. They fit snugly.
Another thing: weight distribution.
If you put a 25-pound plate on the left and nothing on the right, you’re asking for a disaster. The glide board is held on the rails by rollers. Uneven weight causes the board to twist. This creates "rail bite," where the rollers grind against the side of the metal tracks. Always keep it symmetrical.
Some people think they can use the weight bar for every exercise. While it’s great for chest presses and squats, be careful with the toe bar exercises. If you have 50 pounds of extra iron on the board and you’re doing calf raises, that weight is bearing down directly on your ankles and the pulley attachment. Start light. Seriously.
Is it Actually Safe for the Machine?
This is where the debate gets heated in the home gym forums. Total Gym as a company is pretty conservative with their weight limits. If they say the limit is 400 pounds, they mean total weight—user plus the added plates.
If you weigh 300 pounds and you add 100 pounds of plates, you are at the absolute limit.
The rollers are usually the first thing to go. You’ll start feeling a "thump-thump-thump" as you slide. That’s a flat spot on the roller caused by excess pressure.
- Check the Bushings: If you're using a weight bar regularly, inspect the area where the bar passes through the glide board.
- Lubrication is Key: Use a high-quality dry silicone spray on the rails. Avoid WD-40; it attracts dust and turns into a sticky paste that will ruin your workout.
- The "Ear Test": Listen to the machine. A healthy Total Gym is almost silent. If it's groaning, you've over-weighted it.
Getting the Most Out of the Bar
The total gym weight bar shines during the "Big Three" movements on the machine.
First, the Leg Press. The Total Gym is essentially a vertical leg press if you get the incline high enough. For most fit adults, body weight isn't enough for legs. Slapping two 45s on the bar changes the game. Suddenly, your home gym is a legitimate squat rack alternative.
Second, the Chest Press. If you find yourself hitting 30 reps easily, the weight bar allows you to drop back down to the 8-12 rep range, which is the "sweet spot" for hypertrophy.

Third, the Seated Row. Adding weight here helps balance out the posterior chain. Most people have overdeveloped chests and weak backs. Use the bar to load up those rows.
Actually, there’s a secret benefit most people don’t realize. The added weight of the bar and plates makes the glide board feel more stable. It anchors the board to the rails. If you’re a lighter person, sometimes the board can feel "floaty" at high speeds. The bar fixes that. It gives the machine a more commercial, heavy-duty feel.
Misconceptions About Weight Bars
A lot of people think the weight bar is just for "bulking." That's a bit of a myth. It's about progressive overload. If you don't increase the challenge to your muscles, they won't change. Whether you want to "tone" (which is just building muscle while losing fat) or "bulk," you need the ability to adjust the resistance beyond what the incline settings allow.
Another misconception is that the bar gets in the way of your legs. If you buy the official version, it's positioned underneath the board in a way that your calves shouldn't hit it during a normal range of motion. However, if you're very tall and using a smaller model, you might have to adjust your foot placement on the squat stand.
Actionable Steps for Your Next Workout
If you’re ready to stop plateauing and start using a total gym weight bar, follow this progression to keep your machine (and your joints) in one piece:
- Verify your model's capacity. Look at the sticker on the bottom of the frame. Subtract your body weight from the total weight limit. That is your "safety ceiling" for plates.
- Start with "Small" Iron. Don't jump straight to 25s. Buy a pair of 10-pound standard plates. See how the rollers feel. If the motion is still smooth, you’re good to go.
- Inspect your cables. Added weight puts more stress on the steel braided cables. Look for "bird-caging" (fraying) or cracks in the plastic coating. If the cables look worn, replace them before adding the bar.
- Balance the Load. Always load and unload the bar while the glide board is at the bottom of the rails. This prevents the board from sliding down and pinning your fingers.
- Focus on Tempo. Because you're adding mass, momentum becomes more dangerous. Use a 2-second eccentric (lowering) phase to make sure you're controlling the weight, rather than letting the weight control the machine.
The Total Gym is a fantastic piece of equipment, but it's not magic. It's subject to the laws of physics. By adding a weight bar, you're effectively bridging the gap between "calisthenics-on-a-board" and "weightlifting." Just respect the equipment, watch your limits, and keep the rails clean. Your muscles will thank you, and your machine will actually last a lot longer than if you were trying to "explosively" move your body weight to get a workout.
