Practicing with the skipping rope will help build your explosiveness and your elasticity, which will allow you to generate more power to jump higher.
This skipping rope is one that is designed for speed so you can do single-unders, double-unders, and triple unders.
As a high jumper, you want to maximize the amount of vertical force on your take-off foot.
Use this skipping rope to develop the power in your double-foot and single-leg take-offs.
Commit to using this skipping rope at least 3 times a week and expect to improve your vertical jump in 30 days.
