A muscle mag. that I read is constantly talking about the affects of high intinsity training for burning fat. A Bro of mine gave me some old issues of that mag (Muscle Media) and it says "We've been told that low intensity aerobic exercise is the best method for ridding the body of excess fat." "The reason this low effort theory of aerobic exercise came about is a study showed low intensity exercise burns a greater percentage of calories from fat as apposed to carbs; however, when high intensity exercise is practiced, the research showed the percentage of fuel from carbs is increased, while the amount of fat utilized is greater than or equal to that burned during low intensity exercise." The article goes on to say that the amount of colories burned throughout the rest of the day is significantly greater ( with high intensity) because it raises your metabolic rate higher than walking or jogging, & also keeps it boosted for a longer time period. I thought i would give it a try and i've lost 3lbs in the last week. i'm assuming its mostly fat I havent been feeling tired or sluggish like i would if i were loosing muscle tissue. I'll give it about 3 more weeks and get my body fat% retested. Ive also got an eca stack im getting ready to start, hopefully that'll help accelerate my fat loss. Hope thats of some help Bro.
