Just started to run in the mornings and had a couple questions. How long can the average person run on an empty stomach without losing some muscle mass? Also I go back to the gym later in the day to lift weights and also run afterwards for about 30 minutes. I used to work out seven days a week but got busy and lazy, haven't been to the gym in months. Really sucks had been going religiously for a couple years, 365 days a year. All my effort over the past years was for nothing, lost my size and gained a crap load of weight. Went from 180 to 220, damn I got fat, also only 5'10", so actually I am now short and fat, oh well working on it once again. Ok let me get off my soap box and get back to the topic. Would running twice a day be overkill if trying to maintain what muscle mass I still have, if not I was thinking of biking at night. Thanks in advance for your help.
