• On Leg Extension Machine, raise weight until legs are fully extended; hold
• Lower with control until knees are bent almost 90 degrees; repeat

Coaching points: Don’t rush exercise; go through full range of motion // Briefly hold contraction at top of movement // Bring legs down to 90 degrees and lift to full extension
Goodstein: [This exercise is like a repetitive kicking motion], so keeping their legs strong in the final 15 degrees is important.
