Toning exercise for your abs, arms and legs from celebrity trainer Gunnar Peterson.

Alright, the next move is a plank. You could do it from the forearm or you can do it all the way up on your hands. I am gonna be just using the forearms. Pull the abs in, feet together. Lock your body up, work on your posture. Relax your hands. No stress in the hand. Make sure you keep breathing steady. Let's do this for time. Start with 15 seconds, work your way up to a minute. Steady breathing, abs pulled in. You don't have to stay on this the whole time. You should be doing your own work now, not just staring at me being still.
