Since I can't get out and climb as much as I want, I finally decided to invest in some plywood and make a half way decent home gym. This gym is currently 4 4x8 pieces of plywood with about 100 holes per sheet. I pounded in the T-Nuts and then just screwed them into the existing framing of the garage. The wall it not strong enough to hold anything off vertical and I didn't want to modify the structure since we live in a Condo. It is a pretty good compremise for now.

Along with the wall, I have an 8 foot long set of metal monkey bars in the rafters, a campus board with two sides, and a pull up bar. This give me enough variaty so I do not get bored. I often hang a rope from the rafters to practice jumaring as well.
