Start sitting on your mat with your legs bent in front of you and your arms behind you, palms flat on the ground and fingers pointing away from your body.
Lift your butt a few inches off the ground, squeezing your glutes and pulling your core toward your spine.
Lift your left foot off the ground and extend your leg, bringing it towards you as you simultaneously reach your right hand toward your left foot. Tap your left foot with your right hand or get as close to it as you can while keeping your butt and core lifted. To modify, keep your left leg bent and touch your knee instead.
Set your left foot and right hand back on the ground but keep your butt in the air.
Repeat on the other side, tapping your right foot or knee with your left hand.
This counts as one rep. Complete as many reps as you can with proper form for 40 seconds, followed by a 10-second rest.
