I recently got a stand for heavy bags and Im hanging a 50 LB bag on it right now, the bag is attached by a spring and the purpose of the spring is to absorb some of the impact when the bag is struck as well as some of the weight of the bag so there is less stress on the straps that the bag hangs from. From my experience in the past, the straps are the first things to break when you hang a bag. So the spring is supposed to help prevent the straps from breaking and this is the first time I've used a spring. Im wondering if it would be a good idea to only hang the bag when Im using it for a workout, if I should take the bag down after every workout, or if I should just leave it hanging even when Im not using it. I do eventually plan on getting other bags of different weights but for now Im just starting out with the 50 LB bag. Advice?
