Re: Indoor heavy bag options
Know that wherever you hang that bag, there will be a lot of vibration going on in other parts of the house/apartment when using it. I once hung a 100 lb. heavy bag in my attached garage and one day while really getting after it, my wife ran outside saying her miniature glass figurines were falling out of a display hanging on the living room wall 2 rooms away.
Living in an apartment may bring some complaints by your neighbors when you use it. Just a bit of heads-up.
