Begin with 1 minute of traditional rope jumping. Continue jumping for 1 minute more, but begin twisting at the waist, keeping your upper body straight while pivoting your legs to the right and then the left with each jump.
Trainer tip: Be sure to twist only from the waist down.
Lay 2 jump ropes on the floor in an X. Begin standing with both feet in 1 of the sections, facing the jump ropes. Bend your knees and jump forward, landing in a squat position with 1 foot in each of the next 2 sections. Jump forward again, landing with both feet in a squat in the last section. Turn around, and repeat. Go back and forth as quickly as you can for 2 minutes.
Trainer tip: Keep your knees over your ankles when you land.
