Pull Ups

Core strength is a vital component to pull ups, this is because your abs are heavily relied on to create stability and stillness under the bar when you hang from it. You therefore need to incorporate more hanging ab exercises into your routine to start to strengthen your abs in that environment which will have a great transfer into the pull up.

You also need to have a strong deadlift. The stronger you are at the pulling, the better you are going to be at pull ups. You must also have a strong and stable scapula strength. A great way to do this is improve your straight arm scapula strength, such as the straight arm pushdown. Finally you need to ensure your body fat is in check. If you are heavier and you don't have the strength to match that extra weight then pull ups will be incredibly difficult. Having a good strength to bodyweight ratio will improve your ability to perform more pull ups.
