Mixing intensity workouts:Effective in Fat loss

Training like a sprinter is more effective for fat loss. Running 3-4 miles a day can certainly lose weight. By doing long, slow aerobic training one can lose fat, BUT it's certainly not the most effective way to do it. First, you will lose lean muscle. That's why elite distance athletes look so skinny and have little muscle. Secondly, it's just not the most EFFICIENT way to exercise. Your body is good at adaptation and the more distance you put it, you have to run even further next time to get the same benefit. Soon, you'll find yourself running 5 miles to get the same benefit that 4 miles used to get you. That also leads to more potential overuse injuries. You should do what you enjoy doing most. If you LOVE doing distance runs and have the time, then go for it. If you love yoga or pilates, then do that too. Do what you enjoy. BUT, I strongly recommend you mix in some high intensity exercise days at least 2-3 times a week.
