Just a simple project to get a decent bar. I used 2 pieces of foam from a useless leg extenstion for a crappy york bench.
I never done a whole lot of zechers squats - but enough to know how uncomfortable they are! - since i have a knee issue i try to keep the load light compared to a back squat.
I also believe its a damn good everyday lift if you do any labour type work. When will you walk around with something on your back shoulders like a back squat?
Extra note: I have the collars soaking in a cleaner now to clean them up - they are older then me probably. Then i will take out the measuring tape and secure the collars onto the bar.
