I work as a track controller at NOLA Motorsports Park, mostly throwing flags at the karting facility. So naturally my arms and shoulders get an intense workout. I've gotten myself sore a few times now, mostly in my shoulder and was wondering if there are any stretches or flexibility training routines that would be helpful in preventing any injuries. The flags I use are heavy rip-stop nylon, about 2' x 2.5' on 1" wooden dowels and the checkered is particularly heavy thanks to the matting and extra stitching. I usually switch back and forth between my left and right hand to get an even workout but i was wondering if there was anything else i could be doing to protect myself.
