My transition from “..ehh” to “YEAH” happened once I began incorporating that little piece of metal into accessory work with half-kneeling single arm overhead presses.
Since then, I have found there to be so many reasons to integrate them into my program & my clients.
They bring so much versatility to your traditional lifts (that some people may get bored with after a bit).
The equipment needs are minimal & you can “hack” the set-up if you decide the $20 attachment isn’t worth your money.
They offer simple modifications for lifts we want to (read: should) incorporate that may cause discomfort due to lack of mobility, previous injuries, etc.
