This very high-intensity exercise strengthens your back, hips, and legs. It's great to use if you want to see quick results, but be careful not to overuse this exercise or you'll end up injuring yourself.
Getting in the Starting Position
Performing the Exercise
1To make this exercise more challenging, use a power jumper cord while you work. You can also increase the height of the block if you wish, but be very careful if you decide to do this—bigger drop means bigger strain on your joints, which could result in injury. 
1Do 6 repetitions of this exercise per set. Repeat until you've completed 2 to 3 sets.
2In order to start seeing/feeling results, aim to do 2 to 3 sets 2 to 3 days a week for 4 weeks. Be sure to take at least 2 to 3 minutes between each set and to rest at least one day between workouts—depth jumps can be very hard on your back and knees, and overusing them as an exercise tool can cause serious injury.
- The benefits of these exercises are increased strength and flexibility in your legs, back, and hips.
- To make this exercise less challenging, jump from a lower platform. In fact, you may want to start out by jumping straight off the ground and working your way up to a higher level.
- Those with bad knees should be careful when performing this exercise.
- Potential injuries to your spine and knees may be incurred if this exercise is performed incorrectly.
