One of the simplest and most effective ways to exercise your abductor muscles is with what is known as a Windmill exercise. All you need to do is lay on your back with your arms outstretched to the side and your legs as straight as possible. Taking your left leg, lift this to a 90° angle and then turn to the right, crossing over your right leg, and touch your left leg onto the ground near your hand. For those who are little stiff, it may take a while before you can comfortably touch the ground as you cross over but you will feel the benefits. Once you have taken your leg as far as possible, return back to the starting position and then try this with your right leg moving towards the left side of your body. It is advisable to start with between 10 and 20 repetitions and this is not only a great way to warm up but also perfect for exercising your abductor muscles.
