This sliding side lunge is great for targeting your inner and outer thighs, glutes, back, and abs.
Stand with your weight on your right leg, with one paper plate under your left foot. Bend your right knee and push your hips back behind you, sliding your left leg out to the side. Keep your left leg straight. Bend your elbows about 90 degrees and swing your left arm in front, right arm back. Quickly bend your left knee and slide your foot into your right, swinging your right arm forward and your left arm back. That's one rep. Repeat 15 times with the left leg, and then 15 times with the right.
Tip: Press down through the ball of your foot into the paper plate to keep it in place.
