Jeep was a beast, no doubt.
Jeep did something funny. . . We've all used straps for heavy shrugs, bentover rows, etc. I've done 1,000's of reps (lifetime, not one set) with 600-700 pounds and I have never broken a wrist strap. I've worn them out and thrown them away but never broken one. I would give Jeep a brand new pair of good quality straps (on back day) and he would return them in an hour or so and one strap would always be torn in two. He would say, "Sorry Tommy, they just don't make them like they used to."

I don't know how he was breaking them.
