Weighted Muscle up (on bar)

How to do the Weighted Muscle up (on bar)

1. 1Attach a weight belt or put on a weighted vest, then approach a sturdy pull-up bar. Grip the bar slightly wider than shoulder-width using a false (thumbless) grip, palms facing away.
2. 2Hang in a dead hang with arms fully extended, core braced and body still.
3. 3Initiate a powerful pull by driving your elbows down and back, engaging your lats to accelerate your chest toward the bar.
4. 4As your chin clears the bar, aggressively lean your torso forward and push your elbows up and over the bar to transition above it.
5. 5Press through your palms to lock your arms out fully, finishing in a support position above the bar with your hips at bar height.
6. 6Lower yourself under control — reversing the movement — back to a dead hang.
7. 7Complete your reps, then dismount the bar safely by stepping or dropping down in a controlled manner.

Form tips

• Use a false (thumbless) grip from the start — it allows your wrists to rotate freely through the transition and makes the movement significantly more efficient.
• Brace your core and squeeze your glutes throughout every phase to prevent swinging and to protect your lower back under the added load.
• Film yourself from the side periodically — a stalled transition is almost always caused by not leaning the torso forward aggressively enough as your chest clears the bar.
• Build a solid base first: achieve at least 10 strict pull-ups and 10 strict bar dips before attempting the unweighted muscle-up, and master that before adding any external load.

Common mistakes

• Using a kipping swing to power through the movement, which reduces back and core engagement and places excessive rotational stress on the shoulder joints.
• Failing to lean the torso forward during the transition, causing the lift to stall at bar level and forcing an asymmetric 'chicken-wing' arm-over-arm workaround that loads one shoulder unevenly.
• Skipping the core brace, which allows the lower back to hyperextend under the additional load and increases the risk of lumbar strain.
• Gripping with thumbs wrapped around the bar, which restricts wrist rotation and makes the transition phase awkward and inefficient.
• Adding too much weight before the technique is flawless — the weighted muscle-up magnifies every flaw, and a breakdown at the transition point risks acute injury to the shoulder or wrist.
