Korfball drill: jumping rope (jump strength)

Skipping Ropes. It seems almost too obvious to be true, but regular rope jumping exercises the muscles you need for a vertical jump. To do this, use a hard surface with plenty of room for the rope in all directions. Try to exercise for 15 to 20 minutes a day.

• Do not jump with one, but with two feet at the same time.
• Train to jump faster and faster. Start slowly with a hop between each jump to keep your balance. When you notice that you are getting better at rope jumping, drop the hop and spin the rope faster.
• If you want to do something other than jumping rope, try running up and down stairs. This is a similar workout and exercises many of the same muscles.
