Me and one other boxer from my gym got the honor to go to Nashville TN and get personally trained by Randall Tex Cobb. It was awesome. Huge motivator. Our warm up was to do a 4 mile run up hill with our 18 ounce boxing gloves on keeping them up in our gaurd. I usually just regularly run but keeping ur hands up the whole time made it real tough. Anyone else ever try running like that before.
