Forearm Plank

Start facedown on mat, then prop yourself up with elbows under shoulders with forearms on the floor, hands in fists. Lift hips off the mat, keeping your back straight and abs tight. Engage glutes and legs to prevent hips from lifting or dipping so body forms a straight line from heels to head.


High Plank With Hip Opener

Start in a high plank position, wrists under shoulders, core engaged so body forms a straight line from heels to ankles. Then, plant your right foot next to your right hand, with knee bent. Rotate torso to the right as you extend right arm up toward ceiling. Bring right arm back down to frame right leg, then return to starting position. Repeat on left side and continue to alternate.


Walking Plank

Start in forearm plank position with shoulders over elbows and core engaged. Replace right elbow with right hand, then left elbow with left hand until you’re up in a high plank position. Reverse to drop back into a forearm plank position. Continue to repeat, alternating the lead hand each time.

After completing the move on the right side for 50 seconds, take a 10 second rest then repeat on left side.
