Many reasons: You may be feeling fatigue for several reasons after a workout. If you are severely exhausted and feel incapacitated you may be overdoing it, you may not be eating enough, or you may have a serious medical condition involving your heart or lungs. This may also be due to other conditions such as low thyroid. Follow up with your doctor prior to working out again.
