High-intensity cardio is #1 when it comes to burning fat. Especially in the AM before breakfast and after popping an ECA Stack. Great fat-burner. First thing in the morning Ill run sprints up this hill and walk back down. Ill only run maybe 8 which takes around 15 minutes but its definitely EXAUSTING. Really kills me. Trying to work up to 20 minutes and Ill stick with that.
can be acheived on the bike as well as the treadmill. the main difference is that the bike is easy on my joints, doesn't get me out of breath, and allows me to burn more calories without killing myself. I go with the bike most of the time.
Judging by results for fat loss, nobody holds a candle to Clarence "Ripped" Bass, and he recommends (and cites studies for) high-intensity sprinting sessions.
