Here is a link to the CrossFit Journal article on building your own garage gym for the price of a one year membership at a globogym (i.e. Gold’s, Bally’s, L.A. Fitness, etc)…spandex is optional. Edit: This article is now only available with a subscription to the CrossFit Journal, but believe me, since you get access to EVERY article ever written, it is worth it!

Medicine/Slam Ball – Make your own.  Get a basketball, drill a hole in it and fill it with sand.  Use a scale to get the ball to 15 or 20 lbs.  Before you seal the ball back up, get some air back in it, that will let it bounce stightly.  These are great for thrusters, wallball, overhead squats, medball cleans, slam ball etc.  

Make your own Kettlebells!
