In beginners, barbell deadlift training boosts the pace of torque generation and vertical jump performance. In more experienced athletes, it may help increase peak power and decrease time to peak power during a vertical jump. The best way to develop your vertical leap is with practice. You can use different techniques to enhance your movement quality and increase the range of motion when jumping. For example, you can work on stiff-legged jumps or boundsing (jumping as high as possible). The more often you do this, the better you will become at generating higher heights. Deadlifts are one of the most effective ways to build muscle strength and power. They also improve posture and give you an overall stronger body. If you want to be able to jump higher, then consider adding some deadlift exercises into your routine.
