I only have room for one in my garage gym. I’m debating on either a concept 2 rower or a Xebex air bike. They are both priced similarly. I do a push pull legs routine and HIIT with either battle ropes, jump rope, kettlebells, or sprints. I’m leaning towards the rower because it gives a nice full body workout but my friend is pushing me towards an assault or xebex bike. I train for overall athleticism and to stay lean. My home gym consists of a rogue SMl-2 half rack, barbell, Swiss bar, trap bar, 400lbs of weight, iron master 120lb adjust dumbells, Rogue rubber bands, some kettlebells, ghata macebell, titan press, land mine, and some other random stuff.
