With your palms flat, raise onto your toes in a high plank position. Keep your hands directly below your shoulders, feet at hips-distance apart, and core engaged.
Lift your right hand off the floor, pulling it up towards your armpit with your elbow bent.
Place your right hand on the floor and lift your left hand. Keep your core tight to avoid rocking from side to side.
Place your left hand on the floor and press back into a down dog or pike position, lifting your hips and straightening your legs.
Reach your right hand back toward your left ankle or shin, coming as close to touching it as you can.
Return to plank position, then lift back into downward dog and repeat on the other side, reaching your left hand to your right ankle or shin.
Return to high plank to complete one rep.
Complete 10 reps, or do as many as you can in 45 seconds.
