Well now, a barbell with weight capacity between 55-95 pounds, an elastic band thingy, and something to do chin-ups on. I have the push pull tower and find that to be perfect. I also have an Iron Gym...that pull-up bar that goes on a door frame. Well, unless you have great upper body strength already, then maybe the IG is for you. But I can only do 4-5 reps on that...and that is after doing STS all the way thru once. Before STS I could only do 1 good rep on a good day. I love STS and plan on doing it again late summer into the fall. I got great results and know I will do even better the second time around. Hope this helps.
