Do any of those other gimmicks like jumpsoles and rubber bands work?
They might work but only for this reason: Let’s say I take a group of fat people and give them a fake magic pill and tell them the pill will make them lost 25 pounds in 3 months. I then take them out and run them 5 miles each and every day. Three months later all of them have lost 25 pounds. Was the pill responsible for the weight loss? No. they lost weight because they got up off their butt and exercised. All training gimmicks work the same way. All of them have workouts you have to do along with the gimmick and doing anything is better than nothing.
