I do not want to start an argument here corifeo, but #3 and #4 are completely false."
"Where are you getting that information from? #3: Muscles don't consume oxygen?"

Basic biology....


There are two forms of cellular respiration Aerobic respiration, a process that uses oxygen, and anaerobic respiration, a process that doesn't use oxygen, those are the two forms of cellular respiration

Oxygen is required in the process of turning carbohydrates and fat into energy for the muscles to use, that's why the act of lifting weights causes increased heart rate and labored breathing just the same as a short sprint would.

Oxygen is only use for aerobic respiration not for anaerobic respiration, don’t worry a lot of people do not know this.

No you are confusing both physiological events, any physical event that only last less the 2 minutes is more likely than not an anaerobic event.

#4 go pick up a 10 lb barbell and lazily curl it 10 times. No significant increase in heart rate, no increase in breathing labor. Now pick up a 65 lb. barbell and curl it until you reach muscle failure, and add in 2-3 rest pause reps. Your heart will be pounding and you'll be gasping for air. Try to tell anybody that the calorie burn is the same for either case, go ahead.
