Explosive Step Ups
To do Explosive Step Ups, pick a step, chair or park bench that you can explode up off of that isn’t too high. Beginners should use a lower box while advanced exercisers will want to use a higher box but something they can still easily perform a Step Up on.
To start, place one foot on top of the box (or whatever you are using). Driving up off the foot on top of the box, jump up in the air off the box.
In the air, switch and land with the other foot on top of the box. Touch the other foot to the ground and then explode back up, pushing mainly off the foot on the box.
Jump up as high as possible, driving off the foot on the box to switch and land with the other leg on top of the box. Keep alternating until all reps are complete.
Don’t jump to simply tap your toe on the box. Your weight shouldn’t be back so you can tap your feet on the box.
Truly explode up off the box.
Use your arms to help propel you up as you jump. When you land swing your arms back and as you jump swing your arms up overhead.
