This traveling lunge targets your thighs, hips, and glutes, plus the reaching motion adds an extra core challenge.
How to do it: Stand tall with your feet slightly wider than hip-width apart, hands clasped behind your head.
Cross your right leg behind your left and lower into a curtsey lunge, reaching your right hand to the floor [as shown]. Quickly stand back up and return to start. That's one rep. Do 20 reps total, alternating sides each time.
