I recently bought a road bike in order to achieve some weight loss. Im wondering what heart rate levels people recommend for greatest success. From everything I have read people recommend exercising at at roughly 60% of your max heart rate since you burn the highest percentage of calories from fat in this "fat burning zone." I always had thought that people recommend this because you are able to sustain say, a 140bpm for a LONG time. However, if someone is able to sustain say, 170 for roughly the same amount of time, wouldn't that person burn more calories total and in turn more calories from fat?
Im just wondering because I have exercised fairly regularly throughout my life but have always struggled to lose weight. Im sure most of this is diet related but even times when Ive really cleaned up my diet, I have still struggled to drop lbs. The only reason I can think of is that I am always working out above the "fat burning zone." I always have trained with a HR monitor just to see what my HR is and Im usually working out around 155-160bpm.
Now the next interesting point to this is I have usually just worked out by running. Whenever I would go for runs my HR would be around the 155-160. If I tried to push a little harder and get my HR up to 170-180 I would only be able to sustain this for a few minutes. However, when Im on the bike, I can ride for 1 hour or more with my HR around 170. Im not really sure why this is.
So 155ish is comfortable for me to workout at but I have struggled to lose weight in the past. Should I try working out at a lower HR for longer time periods, like 2 hours? Or should I try working out at the higher HR for the same amount of time as my comfortable 155ish workouts. Or the higher HR for longer time periods, like 2 hours?
Hopefully this isn't too much gibberish and someone can figure out this novel I just wrote, lol. Thanks for the help
