Jumping rope is excellent cardiovascular exercise.

If you want to do it with style and variety, try these techniques:

  • One-foot jumping. With each jump, hop on one foot and kick the other foot in front of you. Then alternate from foot to foot. The kicking foot should be raised just a few inches off the floor; you're not looking for dramatic movement here.
  • Weight-shifting. You'll feel like a boxer-in-training with this one. With each jump, shift your weight lightly to one side. Then alternate from side to side. Keep your body low and your knees bent slightly.
