My MMA gym has a decent weight room/cardio area that I use.
The only things I have at home at the moment is my heavy bag and an elliptical machine that I don't really care for.
In the future I plan to get :
Bench
Squat rack
Pull up bar
Speed bag
Kettle bells
Treadmill
Mats
Then the only thing I'd need to leave the house for are BJJ/Muay Thai classes.
"24kg KB, pullup/dip station and running shoes."
Forgot to include a foam roller.
