How about a DAILY CHALLENGE!! How many pull-ups can you do at the gym today? Strong back=powerful body. Shoot for 2-4 sets.And they ABSOLUTELY can be modified!! And if you can only do 1….GREAT!!! Try for 2. Go for a personal best. For my athletes out there, I expect 5 sets of 15/20. For the beginners, however many you can do in a set is enough. The message here is to push to another level…you can do it!!
