Reverse Lunge High Knee
Stand with feet hip-width apart, holding a weight in each hand by sides. Step left leg back into a reverse lunge, bending knees 90 degrees to start.
Stand up on right leg and bring bent left leg toward chest. From here, immediately step left leg back into lunge (without touching foot to floor in between). That’s 1 rep. Repeat for 60 seconds. Switch sides; repeat.
Scale down: After lunge, return to standing on both legs before bringing knee to chest.
