No sane person has a garage gym and a basement gym. Fortunately, I never made a claim to sanity.
The space is 2 horse stall mats (48 square feet), a Raptor Yoke custom cut to 84" tall to fit in the basement, a Cybex bench, EliteFTS squat box and 140# of dedicated plates (2x45 and 2x25). The barbell and change plates are shared with the garage gym.
This is a near ideal powerlifting set up. Due to the ceiling height, overhead movements are not feasible. I could do a variety of functional fitness movements, but would hate to dump a barbell.
The primary consideration is temperature. It is often cold in the garage. Cold is usually tolerable, but this takes away that last excuse.
I also have my stationary bike set up in this space.
Longer term, I would like to buy some change plates and a barbell. It would also be convenient to have a timer. I should at least get a clock down here.
