<p>Couldn’t agree more. Practice is the only thing that is going to make you better at pullups. Also swimming, lifting, and doing lots of pushups will help develop your upper body strength to give you a few more. Just keep working at it! I think Bullet’s advice is the best you can get. At the Academy, I will do a pullup in my room every so often during ACQ (you can hang from the shelf in the closet :)) and that kind of repetition will help more than anything!</p>
