A cool core exercise that also brings in other muscle groups into play and helps on the flexibility of your calves. Perform it as part of a warm-up, a filler training routine to a more intensive workout or an any place, anywhere kind of exercise. (Well, almost anywhere. You need to exercise your judgement).
What's involved: Triceps, hips, shoulders, core, calves.
Powered by: Calves (the body saw motion), core (sustaining the pose).
Tip: When you perform this try and take your body as far forward as you can and then rock it back as far as it will go. You should feel a pull on your calves as the muscles stretch.
