Today in the vein of being helpful and all, I wanted to show anyone who has difficulty with pull ups (you’re in good company, trust me) a variation to an assisted pull up- negative pull ups!
Basically, you jump up on the bar so your chin is above the bar, or the “top” position, if you will. You then slowly lower yourself into a full hang with your shoulders still engaged- the slower the better for this. This method was introduced to me by John and I have found to be pretty effective in getting to a point where I can do one and the occasional two pull ups.
Here is a a photo to illustrate:
This is an illustration for a chin-up, but you get the idea.
Hope that helps!
