- Stand in front of a box. If you're new to box jumps, choose a box that's 12 inches high. If you're more advanced or taller, go for a 24-inch box.
- Use your starting position to set up the entire movement: engage your core, bend at the knees, and allow your arms to provide you with momentum, jumping onto the top of the box. If this is too hard, just step up with one foot at a time.
- Step down with one foot at a time to complete one rep.
- Do as many reps as you can for one minute.
If box jumps or step-ups aren't for you or you don't have access to a box, do jump squats instead.
