Yeah I do. I **** you not, while working for United Parcel Service, I unloaded a 40ft trailer by myself in 40 minutes. Loaded with boxes from top to bottom, aft to stern. While I did not do that every night, I did average about 50 minutes a trailer. Best shape I was in, in my whole life. My back, biceps, triceps and lats looked like Swarzenegger during his championships. Oh the days...
