Strict Pull-up - Pronated
Cues:
Start in a full passive hang with overhand grip
Activate the pull through the back and scaps first, then pull with the arms in one motion
Keep the head level and pull until the chin is well above the bar
Return to a full hang each rep
Mistakes:
Starting from bent arms, or without settling into a full passive hang
Pulling with arms first
Reaching with the chin to strain for extra distance the back and arms should accomplish
Failing to reach a full hang on every rep
