Hey
Im a 21 year old college student, i currently weight 215 and im 6'0 tall. I used to be in extreamly good shape, 2 years ago i was sitting on 170 lbs. But the burdens of college and a job and studying ive been unable to really keep in shape, not to metion the crappy food i eat.
I started running and adjusting my diet last week. Since last monday, i was 223 and today im 215 so i lost a bit of weight. My workout routine is simple, 3 miles in the morning and 3 miles at night. My question is what is the importance of keeping your heart rate at a certain level while running? i been reading how you should keep it below a certain level of bpm in order to burn fat and if it exceeds that you will burn muscle? What exactly is the science behind this?
also, the charts on the threadmills gives you a heart rate percentage based on your age. Well at 21 and weight 215, i figure my heart shouldnt be beating more than 140 beats per minute....but i run at 5.1 mph for a good 3 miles and the monitor says my BPM is like 170-190. Why running so slow is sending up my bpm so high? 5.1 is slow, idk if i'll like running at an even slower pace to keep my heart rate lower. Will my bpm adjust as i run more often? Thanks in advance for any help
