2. Arms: Downward dog push-up
2 x 10 reps, 15 to 30 seconds rest between sets

Kneel on hands and knees, and then push back to straighten legs and open shoulders so your body makes an upside down V shape. Without letting shoulders fall forward, bend your elbows to the side and touch your head between your hands. Push back to the downward dog position. Repeat.

Why it works: This exercise is perfect for the mesomorph because it's challenging but also helps to maintain hamstring and shoulder flexibility.
