I've been following a slightly modified version of couch to 5k, I only run 2 days a week instead of 3, my off days from the gym. I got a fag health watch and did my first run today with it, 15 min run, 2 min walk x2 and these are my stats. Am i going to end up having a heart attack running or is this ok? More importantly how bad is this for losing muscle? Would I be better just incline walking? The main reason I started running was to lean out the last bit sooner. 6ft 85kg
