We love that CrossFit has popularized box jumps again. The exercise builds explosive power, trains your fast twitch muscle fibers, and makes you more athletic. 

What we don’t love? The fact that most people do them wrong, according to Men’s Health Fitness Director BJ Gaddour.

Follow the jumping, landing, and dismounting tips in the video above, and you’ll safely build more strength, stability, and power from start to finish. Keep an eye out for additional ways to increase single-leg strength and starting strength, too. 

Once you nail the correct form, add box jumps to your workout. For maximum power, do sets of 3 to 6 reps every 2 to 3 minutes. For a conditioning stimulus, go for 10 minutes straight, alternating which leg you step off the box with each time.
