Box Jumps have become one of my favorite exercises for HIIT training and lower body development. Having a strong lower body, and core are essential when executing mid to high box jumps. As you get stronger and have more range of movement in your lower body, you can achieve alot of HIIT/PLYO exercises.
Always warm up and stretch. Practice makes perfect, and yes even I do miss the high boxes at times, which is not good as it takes a toll on your shins, lol.
Stay Focused & Train Hard
