3- Wrist Extensors
This muscle is found on the outer edge of your forearm. It’s not a large muscle, but it plays the very important role of extending your wrists. By working this muscle, you can improve your grip strength and reduce the risk of wrist strain when performing push-ups and pressing exercises. Reverse Wrist Curls will strengthen your wrist extensors and allow you push/pull heavier weights!
4- Tibialis Anterior
This is the muscle that runs along the front of your lower leg or “shin”, the muscle that gets sore when you run. It will help to round out the appearance of your lower leg (in tandem with your calves), and will enhance your mobility as you run, walk, or play sports. You can reduce your risk of developing shin splints (a common newbie runner’s problem) by performing simple exercises that work the muscle. For example: point your toes downward as far as they go, then flex them up toward your shins. You don’t need weights to work this muscle effectively!
