So I'm trying to lose about ten pounds and my base offers a spinning class at six in the morning. I'm thinking I may start waking up early on my off days to go do the spinning class (it lasts an hour) but there is no way I'm going to wake up even earlier just to eat breakfast before I go. Plus, I've always read that you burn more fat if you do cardio first thing in the morning before eating breakfast. So, could I go do an hour of spinning, then some heavy bag work (maybe 15-20 min) come home and do 30min of yoga, then eat breakfast? or should I have something in my stomach if I plan on doing that much?
