The outside gym is cool. I have my squat stand setup outside and it is nice training outside. I don't have a covered outdoor area though was thinking of maybe doing something like that in backyard at new place. All you need is a slab of concrete and a roof just leave the sides open. Of course that is when the weather is nice but I did squats outside here this week wasn't too cold yet. His setup looks ideal half inside half out that is kind of where I am at now as I overflow outside
