Find out how to double your maximum number of pull-ups in just 22 days with this fantastic guide from Jeff at Athlean X.

The first step is to establish your max pull-ups in one set and then work towards completing more pull-ups in a specified timeframe. Rest days are incorporated to prevent muscle failure, and the program continues to progress with each testing day. By the end of the 22 days, you should see a significant improvement in your pull-up ability.
