For everyone who is bored with planks, and feels like it needs a little more of a challenge, try this one out! Bonus points if you can do the whole 3 minutes without dropping your butt.
1 minute: regular plank. While on your belly, lift up to a regular plank on your toes and elbows. Remember to keep your core tight and your butt parallel to the ground.
30 seconds: right side plank. Roll over to a side plank on only your right elbow and right foot. Keep your core tight and straight, try not to let your side droop to the floor.
30 seconds: left side plank. Switch sides and repeat on your left arm.
15 seconds: lift right arm. Roll back to a regular plank, and for 15 seconds lift your right arm straight out in front of you and hold.
15 seconds: lift left leg. Bring your right arm back to normal plank position, and lift up your left leg. Squeeze your butt and keep your leg straight.
15 seconds: lift left arm. Bring left leg down and lift left arm and hold.
15 seconds: lift right leg. Same as before, bring your left arm back to normal position and lift your right leg up for the last 15 seconds. Done!
