Basic Workout: Side Plank. How to do a side plank: Lie on your right side with your legs straight. Prop yourself up with your right forearm so your body forms a diagonal line. Rest your left hand on your hip. Brace your abs and hold for 60 seconds. If you can't make it to 60 seconds, hold for 5 to 10 seconds and rest for 5; continue for 1 minute.
Instead of supporting yourself on both forearms, you will start the plank while laying on your right side. Rise up and support your body on your right forearm. Your feet, knees and thighs will be stacked one on top of the other. In addition to strengthening your core, this move also helps work your oblique muscles.
