SKIP THIS IF YOU DON’T TRAIN LEGS. But if squats, leg presses and lunges are part of your week, you’ll understand why so many lifters wear knee sleeves. 7mm knee sleeves wrap your knees in firm compression, keep them warm between sets, and give you that supported, stable feeling when the weight gets heavy. You don’t need knee pain. You don’t need a huge squat. You definitely don’t need to compete. You just need to train legs. Try one leg day with them. You’ll understand.
