Thanks man, If you haven't already try to start add weight to your pull-ups which will build your strength up so you can do more body weight pull-ups. You can even start with just ten pounds or so and add a few pounds each week. Also try to shoot for like one more rep each week on the body weight pull ups. It can be as simple as rest for 5-10 seconds before trying one more. Or you can add a few negatives after you hit failure. Just step on a bench a jump up to the top and slowy fight your way down to the bottom. I almost forgot to mention than when you can't do any more body weight pull ups you can jump on a pull down machine add countinue to rep out til failure, then drop to a lower weight and continue etc. I love pull ups, so I kinda get carried away when talking about them.
