1. $30 mthly All-Club Membership 24Fit
2. $150 mthly at a good boxing gym w/professional instruction...not some fitness guru. Ok...I'd pay to train w/Tanji Johnson
3. Gymnastics in the backyard w/your neighbor's kids...just cost $3 weekly for ice cream from the ice cream man. Free if you can round up some of the neighborhood stray dogs.
