If you focus on body weight and isolation you can totally get an effective workout at home
Why even get a home gym then?
Why does anyone even go to the gym?
Professional athletes, body builders, fighters, they should all just get a home gym and train in there.
Why don't they? Because it's only effective up to a certain point.
It's really not even worth arguing about. Every single person here who has a home gym will eventually realize they need a full facility to take their bodies to the next level.
Until then, I am wrong and really don't care.
As far as contributing to this thread without bashing it (go to a real gym, etc), is that the only thing useful in a home gym is an elyptical and maybe a bike. That's my feedback.
