Hi everyone! I am new to these forum but have really enjoyed helping others with advice. Now I have a question for you.

Determined to reduce body fat, I have for the past six months, pursued an aggressive workout schedule, which has included hours on end of moderate intensity aerobics. I am a distance runner, presently running up to 13 miles as I train for a marathon in June.

I know you gotta do moderate cardio at three to five times a week for about 45mins to loose fat. So I figuered, since I love doing it and am an endurance athelete and am interested in speeding up fat loss, why not do, say, 2hrs of cardio five days a week. My experience has been less than positive.

I have enjoyed these long sessions, which include running for 30-45mins, elliptical, biking and swimming, one right after the other and in different orders and combinations. I have lost fat BUT have decided that such a schedule, along with weight training, is not sustainable. I got a cold after my first 2hr session last week. I felt nearly 100% this past Monday and did two of these cardio workouts Monday and Wed. I felt like crap on Thurs and slightly better today. Specifically, I felt lethargic and very weak. I rested all day. I felt paralyzed with fatigue, as if my illness returned.

I think that in addition to increased cortisol, immune suppression is part of the catabolism associated with endurance training. I have not experienced this with my long run on the weekends but I think its because I rest the next day. In this case, I am doing long endurance workouts along with lifting everyday. Bad idea.

Anyone else have any experience with this?
