Step by step instructions
Begin in a full plank position with feet together, hands shoulder width. Lunge left leg forward, placing foot in between hands.
Shift weight into left leg and stand up, trying to lift right leg slightly off the floor (if that’s too tough, keep right toes light on the ground), reaching arms down towards left foot. Immediately return to low lunge position and step left foot back to starting plank position. Repeat on opposite side.
