The hip abduction exercise is a great workout to strengthen the muscles in your inner and outer thighs. As you get stronger, you can add resistance in the form of weights or resistance bands.
Step 1. Start on your hands and knees with your hands directly underneath your shoulders and your knees under your hips.
Step 2. Keeping your knee bent, bring your right leg out to the side, aiming to get your knee at the same height as your hip.
Step 3. Replace your leg back down to the floor and repeat on the other side.
