Muscles develop much faster than tendons. Weak tendons can cause elbow pain or tendonitis and limit your progress. Doing eccentric exercises like negatives and isometric holds strengthens your tendons, prevents strength leaks, and improves joint stability which gives you more confidence. Stronger tendons also store elastic energy which helps with explosive movements like muscle ups and even one arm pull ups. #calisthenicstip #pullup #fitness #bodyweightfitness #onearmpullup #muscleup | Tim Vuu
