6. Jumping Jacks: 1 Minute
Works: Shoulders, abdominals, inner and outer thighs and calves
Start with feet hip-width apart and knees bent. Jump out energetically with both legs and raise both arms overhead. Keep your body fully upright with abdominals engaged. Quickly jump back to starting position. Repeat sequence for a total of one minute.
Easier option: Step legs out one at a time; return to starting position.
