Spiderman Lunge with Rotation

How to do it

1. Start in a high plank, hands under shoulders.
2. Step one foot forward, outside the same-side hand, knee bent to about 90 degrees.
3. Lower the hips, keeping the chest lifted and the back leg extended.
4. Rotate the torso toward the front leg, reaching the same-side arm to the ceiling and following it with your eyes.
5. Hold briefly, then return the hand to the floor and step back to plank.
6. Alternate sides for the set time.
