This really comes down to the size of the multi gym you're looking to buy. The best piece of advice we can give is to measure the area that you're planning to have your multi gym and to compare this with the dimensions of the model you want. Also, don't forget to think about the kind of exercises you'll be doing and that you'll have enough room for those too – you'll be kicking yourself if you can't fully extend the leg curler properly, or have enough room to step out and do your cable flies.
