Should You Hold the Treadmill Handrails? What the Research Actually Says
If you've spent any time in a gym, you've probably seen it. The treadmill is cranked up to a steep incline, and someone is leaning back with their arms locked on the rails, almost water-skiing up the hill.
Maybe that's been you. No judgment. Treadmills can feel awkward at first, and the rails are right there.
But if you're giving the treadmill 30 minutes of your day, you want those minutes to count. So is holding on actually a problem? The honest answer: it depends on how you're holding on. The research is more nuanced than the usual "stop cheating" advice.
The short answer
- A light touch for balance on a flat or moderate treadmill probably makes little difference.
- Leaning back and gripping the rails on a steep incline can take away a meaningful part of the work you came to do.
- On a stair climber, even light support lowered effort a little in one study.
The studies behind these points are small, so treat them as useful guidance, not exact numbers.
Leaning back on an incline can cancel out much of the incline
In a 2014 study, researchers measured energy use in 13 healthy adults walking on a treadmill in several ways (Hofmann et al., 2014).
Walking hands-free at a 10% incline, they used about 8.8 calories per minute. Holding the rails and leaning back, they used about 6.0. That was statistically similar to walking hands-free at a 5% incline.
Put simply, in this study leaning back on the rails made a 10% incline cost about the same energy as a 5% one.
When people held the rails but stayed upright, energy use averaged a little lower (about 7.8 vs. 8.8 calories per minute), but the difference wasn't statistically significant. That suggests leaning back and letting the rails carry your weight matters more than simply touching them. With only 13 people, though, smaller effects may have been missed.
On a flat treadmill, a light touch may not matter much
A 2013 study had 12 young adults walk at 3.5 mph and jog at 5.5 mph on a flat treadmill for 10 minutes, with and without handrail support. Oxygen use and heart rate were not meaningfully different between the two (Dalton, 2013).
So if you rest a hand on the rail now and then while walking on a flat treadmill, it probably isn't changing much. That may be different on a steep incline or if you're leaning your weight into the rails.
On a stair climber, light support lowered effort a little
Stair climbers are different because your hands can take a bit of weight off every step. In a study of 15 healthy women on a step treadmill, continuous light or very light handrail support reduced oxygen uptake by roughly 4% to 8% compared with no support (Christman et al., 2000).
That's a modest difference from one study in women, but it can add up over many sessions. Leaning heavily on your forearms likely takes off more, although that study didn't test it.
The part people don't talk about: balance
Walking without the rails isn't only about calories. Your body is also working to balance and coordinate your stride.
A 2025 study used brain imaging on 24 healthy young adults walking at two speeds. Without the rails, walking faster increased activity in several brain areas linked to movement and coordination. When participants held the rails, most of those speed-related differences were no longer significant (Biggio et al., 2025).
This study didn't measure calories. It suggests holding on may make walking a less demanding balance task, which is one reason rails can be useful in rehab. It also means that if you always hold on, you may be giving your own balance and stride less practice.
One more thing: the calorie number on a treadmill screen is an estimate based on things like speed, incline and sometimes your body weight. The machine can't tell whether you're leaning on the rails, so if you are, that estimate is likely to be too high.
Why this matters if your goal is fat loss
Keep this in perspective. A few calories per minute is unlikely to make or break your progress. Fat loss depends mostly on your eating and activity over weeks and months, and strength training helps you hold on to muscle while you lose fat. (If you're deciding where your limited gym time should go, read Running vs. Strength Training for Fat Loss After 30.)
The bigger issue is how you judge your workout. If you set the treadmill to 15% and lean on the rails, it can feel like a hard session even though your body did less work than the settings suggest.
An honest 8% walked hands-free is often a better workout than 15% while hanging on. It may feel harder in the moment, and it's the version that builds your fitness.
How to get off the rails without falling off the treadmill
- Clip the safety key to your clothing. Every time.
- Lower the incline or speed until you can walk tall without holding on. If that's 6% instead of 12%, that's your real starting point.
- Use a fingertip touch while you build confidence. It gives your balance some help without letting you hang your weight on the machine.
- Let your arms swing naturally with your stride.
- Build up gradually. A simple approach: add about 0.5–1% incline or 0.1–0.2 mph only after you can finish the whole walk without needing the rails.
- Use the rails for what they're for: getting on, getting off and steadying yourself if you stumble.
The same idea applies on a StairMaster. Slow the step rate until you can stand tall with your hands off or barely touching.
When holding on is the right call
Sometimes holding on is the smart choice. If you have balance issues, are coming back from an injury, have a medical condition, feel dizzy, or are new to treadmills, hold on. Safety comes before calories. If a doctor or physical therapist has given you specific instructions, follow those.
Frequently asked questions
Will I still lose weight if I hold onto the treadmill?
You can. Weight loss depends on your overall eating and activity, not one habit. Holding on, especially leaning back on a steep incline, may mean each session does less work than the screen suggests.
How many fewer calories do you burn holding onto the treadmill?
It depends on how you hold on, and the research is limited. In one small study, a light touch on a flat treadmill made no meaningful difference. In another, leaning back on a 10% incline lowered energy use by roughly 30%. On a step treadmill, light support lowered oxygen use by about 4–8%.
Should I still do 12-3-30 if I have to hold on?
12-3-30 (12% incline, 3 mph, 30 minutes) can be a useful walk. If you need the rails to finish it, try lowering the incline or speed until you can walk upright with little or no support, then build back up.
Want cardio that fits into a real plan?
Cardio works best as one part of a simple plan. The free 30FIT Jumpstart is a 3-day reset for busy adults 30+ who want to get lean without spending hours in the gym.
If you'd rather have a plan built around your schedule and goals, you can also apply for coaching.
Fitness should fit your life, not the other way around.
