Which is better and burns more fat and cals and carbs and stuff? IF you do sprints, like suicides or 200 yrds. Or like jogging a mile or two? Thanks. I'm really trying to trim down. Im 5 '7 150 lbs. My waist is 33 inch but i wear a 30-31 (strange). Im a guy just to let know. I really wanna trim down a lot this year and if you guys have any suggestions or work out plans, please send them. And to give you my fitness lv, I run a mile in about 6:50.
