- Begin in plank position with legs straight and forearms resting on your mat. Position your feet hip-width apart.
- Brace your core by drawing your navel toward your spine. Now you're in starting position.
- Begin the movement by planting your right palm on the mat and straightening your right arm while raising your body upward. Be sure to keep your torso parallel with the floor the entire time.
- Next bring your left arm to the same position. You'll end up in a straight-arm plank.
- Now, drop your right forearm back down to the mat. Then the left. Now you're back in your original plank position. You've completed one repetition.
- On the next rep, alternate the arm you straighten and lower first so that you work both sides of your body equally.
- Try to do 3 sets of 10-12 reps with 45-second breaks in between sets.
