I’ve been doing pull-ups as part of my workout routine for 20 years (ouch, just typing that makes me feel old!). This is a great exercise because it works arms, core, back, and grip, with almost no equipment needed. The problem that I have is that my grip strength is generally the first thing that fatigues. I’ve had the idea bouncing around in my head for a few years to wrap leather pieces around a pull-up bar. First, I tried to find it for sale, but it didn’t exist! So I bought some supplies online and got to work.
