Jumping Rope- You may not believe it, but it is an easy way to add inches to your vertical leap. Do this as long as you can.
High Jumps- Bend knees between a sitting and standing position. Explode up as high as possibl. As soon as landing, spring back up. Start with 50 and increase by 25 each week.
No Armed Jumps- Same as squat jumps, just don't use your arms to propell you upwards. You can place your hands either behind your back or on your head. Start with 20 and increase by 10 each week.
Mini Jumps- Stand on your tip-toes and jump one inch off the ground as many times as you can. Do this until you feel the burn in your calf muscles.
Jump Ups- Stand on toes with legs relatively straight and thrust yourselves as high as possible. Repeat as soon as you land. Start with 10 and increase by 5 each week.
Chair Jumps- Place one foot on a sturdy chair. Push down on this foot propelling you into the air. As you are coming down, place other foot on chair and repeat. Start with 10 and increase by 5 every other week.
