To improve as a surfer and swimmer, you need to work on strengthening the right muscles in your body, especially your upper body. The Mavrex Surf Trainer lets you do just that. It can be used indoors and outside to work your shoulders, arms, and back muscles. It helps you strengthen your body and increase your endurance.
The Mavrex is also great for kayakers, triathletes, and other sports that require superior upper body endurance. The setup process is pretty easy too. Simply place the hook over your door, hang the units on it, place the anchors over them, and close the door.
