Box Jump (Multiple Response)
Hamstrings


Legs / Beginner / Compound (multi-joint)
A bench explosive exercise for the hamstrings, with the hip abductors, adductors and calves assisting.
Why it hurts: The drills are meant to teach quick, springy contacts; landing heavy loads the shins and knees.
✓ Instead: Stay tall with a slight forward lean and land lightly under the hips on the balls of the feet.
Why it hurts: Poor form under fatigue gets practised and raises the risk of a strain.
✓ Instead: Do drills fresh, after the warm-up and before the main run.
