If you exercise too much it has the opposite effect, and your body will start storing more fat and you will stop gaining muscle due to no recovery period. That goes for aerobic exercise as well, there was a recent study with swimmers and runners, some trained daily, others 2x a week, after 6 months the 2x a week group saw significant endurance gains and the every day group lost muscle and endurance.
My current plan is very simple:
Don't eat crap, and get in 3-4hrs of moderate to intense DEDICATED exercise a week. Actual exercise, not 20 minutes, then 40 mins on your phone. Doesn't matter what day or time, as long as I meet the minimum of 3 hours a week.
