One Exercise, 14 Muscles: Super Plank

This exercise was recently featured in Oxygen Magazine's July, 2011 edition and for good reason. It targets your entire core (rectus abdominis, internal and external obliques, transverse abdomnis, erector spinae), triceps, pectorals, deltoids (posterior, lateral and anterior), rhomboids, latissiums dorsi, teres major and your trapezius.

Give it a Try:

Hold a dumbbell in each hand. Get into a push-up position with your hands under your shoulders and your feet behind you, spread apart for a stable base. Row one hand up to your rib cage and return to push-up position, then do a regular push-up bending both elbows (lowering straight down and then back up). Keep your hips square to the ground and your abs tight. Alternate sides and repeat at least 10 times.

Note: you can modify this exercise by dropping to your knees while in the plank position, just be sure to keep your bottom down and your abs tight.
