Which is NOT listed as a fault in a butterfly pull-up?

• A. Loss of midline stabilization
• B. Elbows back or flaring
• C. Incomplete range of motion
• D. Early transition

Answer: (D)

In a butterfly pull-up, you’re looking for control, full range, and efficient leverage: your core stays braced, the arms move along a tight bar path, and you complete the movement with chest-to-bar or chin-over-bar. The faults coaches typically flag reflect these aims. Loss of midline stabilization shows up as a lack of core bracing, allowing the torso to swing excessively or arch—undermining the transfer of power from hips to pull. Elbows back or flaring indicates poor shoulder and elbow tracking, which disrupts leverage and can stress the shoulders. Incomplete range of motion means you aren’t finishing the pull fully, failing to achieve the required bar height.

Early transition, however, isn’t generally listed as a fault in standard butterfly-pull-up checks. The transition timing is a technical nuance of the butterfly rhythm; it’s not inherently a flaw in form unless it causes the other issues (loss of control, elbows flaring, or incomplete ROM). So the option describing early transition is not considered a fault, which is why it’s the correct choice here.
