Like most of us, it's tough to try and find the right training to fit around a full time job. I work 3 shifts on 3 shifts off (12 hours) and I average around 18-19km a day pushing and pulling weight around. I'm incredibly dedicated to meet the standards required to be a RM and trying to surpass them but I'm aware of over training when you take into account my "work mileage". My question is, I appreciate its a different kind of exercise but if I continue to run after work will this eventually lead to an injury? Should I leave the running to my 3 days off and concentrate on gainers/rest for my 3 days on?
