Begin standing with your arms at your sides. Extend your arms in front of you as you step back into a lunge with your left leg. As you come up out of the lunge, lift your left knee up towards your chest as you simultaneously pull your arms in towards your core to touch right above your hips in a ‘rowing’ motion. Then extend your arms again as you step your left leg back into a lunge. Repeat for 15-20 reps lunging with your left leg, then switch legs and do an equal amount of repetitions on your right leg.
