Explosive Step-Up Jumps

Place one foot on a sturdy box or bench, drive aggressively through the lead leg into a maximal vertical jump off the box, and land softly under control. Key points: - Generate vertical propulsion entirely through the lead leg on the box - Reach maximal triple extension of the hip, knee, and ankle - Land softly back on the box absorbing impact cleanly Common mistakes: Pushing off the ground with the trailing foot instead of using the top leg.
