Lift Stronger, Lift Longer
Strength and muscle gains occur when you push your muscles to their limit. During the repair process, muscles grow back stronger, allowing you to lift more. Weightlifting wrist wraps and lifting straps are a key ingredient in this process. They enable you to fatigue your target muscles without you worrying about your grip failing.
Knee wraps work in a different way, by significantly improving knee safety when squatting. They usually also contribute to a 5-10% increase in the amount of weight you can lift. Knee wraps are best when lifting close to your one rep max, and will help you lift stronger for longer.
