I hope you are not advocating the use of a weight belt continuiously?! Research is showing that the over-use of a belt can/will severely weaken the stabalizing core muscles that make up the body’s “built-in belt”. And, if you need a device to tighted your belt you can be seriously injured from a variety of factors. Namely, by super-elevating interthoradic pressure can cause disc herniation.
Using a belt for extremely heavy sets and/or ballistic reps could be advantageous when working at 90+% of your 1RM. But, the warm-up sets and ancillary work should be done belt-free. Belt use could even be encouraged during max attempts at a pure compression movement, such as the back squat, front squat, and the jerk. Olympic movements besides the jerk and deadlifts are not pure compression and should be done beltless. Search this site if you want to research this topic - there have been some great articles/posts.
