While a punching bag ring isn’t completely necessary for your punching bag, it has a number of benefits for your training. First and foremost, a bag ring creates a stable and “locked” position for your heavy bag so it doesn’t slide around when hit. You won’t have to stop in the middle of your boxing training to drag it back into place and reset. Additionally, if you only have a limited amount of space to practice, ensuring that your bag stays in one place, such as on your exercise mat is key.
