A few weeks ago, I made mention of the Rack workout bar I noticed on an infomercial. The verdict was that although this is a great piece of equipment, it is still grossly overpriced, and not absolutely necessary.
Just recently, I caught wind of this great product sold at Wal*Mart of all places. It is a standalone power tower that pretty much allows you to do all of the most effective upper body exercises, such as pull ups, dips, push ups, v-sits, , levers, planches, and it looks even sturdy enough for muscle ups as well.
If you have space in your room, garage, or even backyard (not sure about how rustproof it is), I would definitely recommend grabbing one of these for the bargain basement price of just $117! I just might order one myself.
