Box Jump

What it is

This explosive exercise builds lower body power and strength. You propel yourself onto an elevated platform using a powerful drive from your legs, primarily engaging your hamstrings. It also strongly works your quadriceps, glutes, calves, abductors, and adductors.

Technique tips

• Stand an arm's length from the box with a slight bend in your knees.
• Use your arms to generate momentum for a powerful upward jump.
• Land softly and silently on the box with both feet simultaneously.
• Absorb the impact by landing in a partial squat position.
• Step or jump down controlled, preparing for your next repetition.
• Breathe out as you jump, maintaining a stable core throughout.

How to track your progress

Log reps, and add the extra load if you wear a belt or a vest. Straddly counts your bodyweight in the estimated max, so added weight and extra reps both show up as progress, and new records are flagged during the session.
