I'm still fairly new to ups and quickly finding out that working on the sort aisle is a workout itself. I'm 5'11 weighing about 225 and work out two to three times a week. I find myself sweating A LOT more than others. I mean within the first 10 to 15 mins, my face is drenched. By the end of the day I look like I just jumped in a pool with my clothes on. Does anyone know as to how many calories one burns when working on the sort aisle? Any thoughts as to why I sweat way more than others? Any insights will be greatly appreciated.
