Walking lunges: Stand with feet hip-distance apart. Step forward with right leg, keeping weight over heel, bending both knees 90 degrees, arms at sides with elbows bent. Be sure front knee doesn’t go past toes and back knee is in line with hip. Push off left toes and lunge forward with left leg. Repeat for total of 2 minutes.
Side shuffle squats: Turn to right side. Take three small steps with left foot to left, followed by right, keeping knees slightly bent. Bend knees 90 degrees into squat, keeping weight over heels (don’t let knees go past toes). Hold one count, then pivot off left foot so you’re now facing left side. Repeat, leading with right foot, doing three shuffle steps and a squat. Continue for 2 minutes, alternating sides.
Knee ups: Find any sturdy elevated surface (a bench, a curb, a stair, etc; the higher the step, the greater the challenge). Step up with right foot, lifting left knee toward chest. Step down with left foot, then right. Repeat 15 times, then switch feet. Continue for 2 minutes.
