Which band should I use?

Use the lightest band that still gets both arms over the bar together for 3 to 5 clean reps. When sets of 5 feel controlled through the turnover, move to the next thinner band.

Why does the band feel weakest at the top?

A band pulls hardest when it is stretched furthest, so it helps most in the hang and least as you rise toward the bar. The turnover and the start of the dip get the least help, which is why most banded reps stall there.

Does the band carry over to an unassisted bar muscle-up?

Partly. It lets you rehearse the full sequence, but the push from under your feet changes the timing, and some coaches skip bands entirely for that reason. Pair it with strict pull-ups, high chest-to-bar pulls and Straight Bar Chest Dips so the strength is there when the band comes off.

Should the band go under my feet or my knee?

Standing in the loop with both feet, as shown, is the most common setup and keeps the pull centered under you. A bent knee in the loop stretches the band less and so gives less help, and either way the loop has to sit deep enough that it cannot slide off.

Should I learn the bar muscle-up before the ring muscle-up?

Usually, yes. A study of 10 trained men doing unassisted muscle-ups found the ring version drew more biceps and forearm activity during the pull and more triceps and biceps activity during the push than the bar version, and its authors suggest the bar may be the easier one to learn first. After the Bar Muscle-Up, the ring Muscle-Up is the natural next goal.

Band-Assisted Bar Muscle-Up

What Is the Band-Assisted Bar Muscle-Up?

Band-Assisted Bar Muscle-Up is a compound exercise that primarily targets the back and also engages the chest, triceps, biceps and shoulders. It is an intermediate-level movement in which a resistance band looped over a pull-up bar takes part of your body weight while you pull up from a hang, turn over the bar, and press into a straight-arm support above it.

The point of the band is practice. A Bar Muscle-Up asks for a fast, high pull, a quick turnover and a deep straight-bar dip all in one rep, and most people can do the pull and the dip separately long before they can link them. The band lets you rehearse the whole sequence at a lighter load, so you can get repeated reps of the turnover instead of failing at it. It is a common way to scale the bar muscle-up in CrossFit-style classes and calisthenics programs.

The lats, teres major and biceps drive the pull until the chest reaches the bar. The turnover hands the work to the lower chest, front deltoids and triceps, which press you up to locked arms. Band tension falls as the band shortens, so it helps most in the hang and least near the top, which is exactly where the transition and the bottom of the dip sit. A thicker band gives more help everywhere, and moving to thinner bands over time shifts more of the load back to your own muscles.

This variation suits lifters who already have solid strict pull-ups and straight-bar dips but cannot yet get over the bar. If even a heavy band is not enough, build up with the Band-Assisted Pull-Up, the Negative Pull-Up and the Straight Bar Chest Dip first. Once a thin band feels easy, the unassisted Bar Muscle-Up is the next step, followed by the Weighted Bar Muscle-Up or the ring Muscle-Up.

Instructions

Loop a resistance band around the center of a pull-up bar and pull one end through the other so it cinches tight and cannot slide.
Stand on a box or step under the bar, grip it overhand with your hands a little wider than shoulder width, and pull the bottom of the loop down to your feet.
Step both feet into the loop so the band sits under the middle of each foot, then press your feet together and point your toes down.
Hang with your arms straight, legs straight and together, and ribs pulled down so your body is long and tight.
Pull hard, driving your elbows down and back, until your chest reaches the bar.
As your chest meets the bar, lean your shoulders forward over it and roll your wrists on top so both elbows come up above the bar together.
Press down into the bar until your arms are straight, finishing upright with the bar at your hips.
Lower under control by bending your arms into the dip, leaning back under the bar and reversing the pull to a full hang.
After the last rep, put one foot down on the box or floor, then slide the other foot out of the loop slowly with your face turned away from the band.

Common Mistakes

Band on the toes
Standing on the band with the tips of the toes, or letting the toes point up, lets it roll off and snap upward.
Chicken wing
Getting one arm over the bar before the other twists the body and puts most of the load on one shoulder and elbow.
Pulling straight up
Pulling the chin vertically to the bar instead of bringing the chest to it and leaning over leaves you stuck under the bar.
Picking a band for the hang
A band that only gets you moving off the bottom gives little help at the top, where the turnover stalls.
Dropping from the top
Falling from the support into the hang jolts the shoulders and elbows and can shake the band loose from your feet.
Stepping off a stretched band
Pulling a foot out while the band is still stretched lets it snap back toward your legs or face.

Injuries

Band-Assisted Bar Muscle-Up is a medium risk exercise when performed with proper technique. The band lowers the load, but the turnover and the bottom of the straight-bar dip still take the shoulder into deep extension with the body's weight on it, which strains the front of the shoulder joint. The elbows and their tendons work hard as the arms switch from pulling to pushing, and the wrists take load as they turn over the bar.

The band adds a hazard of its own. A heavily stretched band that slides off the toes or snaps can whip up toward the legs and face, and a case series of 11 patients treated at one retina practice for eye injuries from recoiling exercise bands found that three of the 13 injured eyes needed surgery, with the authors advising careful checks of bands for wear. Inspect the band for nicks and thin spots before each session, choke it firmly around the bar so it cannot slide, keep it deep under the middle of both feet, and step out of it only from a full hang.

If you cannot get both arms over the bar together, use a thicker band or regress to the Band-Assisted Pull-Up and the Straight Bar Chest Dip until the pull and the dip are both strong. Progress to thinner bands, then to the unassisted Bar Muscle-Up, and add volume gradually, since muscle-up practice is easy to overdo.

Stop the set if you feel sharp or pinching pain in the front of the shoulder, pain at the inside or back of the elbow, or any tingling down the arm. Stop at once if the band starts to roll toward your toes or shows a tear.
