Love pull ups ?
 

If you love to do pull-ups, you’ll find chin-ups fun as well. These are very similar exercises because everything is done in the same manner and under the same principles. The only change is that you need to place the palms facing toward you.

By making this small alteration, you’ll be able to hit the biceps better and develop many upper body muscles at once. Furthermore, weighted chin-ups are good to improve flexibility and get used to your bodyweight exercises.
