I have noticed a few gyms that have their 6' bags rest on the floor and other gyms I have been to have the bags sit about 2-3 inches off of the floor. Is there a reason for one way vs the other? Is one way or the other better or worse?
I dont think it makes much of a difference. Prob preference.
Bag touches floor wont swing. So if you want it to swing leave space, if not then no space.
