I have the benefit of having my own home gym including power rack, 600 lbs of weights, etc. I basicly have the essentials. I am slowly adding belts and whistles to my gym, though I don't need much. I would like to know your opinions on the usefullness of chains/bands for a bjj/mma practioner who only lifts 1-3 times a week. I don't question their usefullness in general but for a non-competitve powerlifter. Do you all believe that they would be a waste of time and money for someone like me?
