Overtraining

 Fail to complete your normal workout

    Some people train to failure as a rule, and that’s fine. I’m talking failure to lift the weights you usually lift, run the hill sprints you usually run, and complete the hike you normally complete. Regression. If you’re actively getting weaker, slower, and your stamina is deteriorating despite regular exercise, you’re probably training too much. Pushing yourself to higher weights and failing at those is a normal part of progression, but if you’re unable to lift weights that you formerly handled with relative ease, you may be overtrained.

Anaerobic/power/explosive/strength athlete, and you feel restless, excitable, and unable to sleep in your down time.

    When a sprinter or a power athlete overtrains, the sympathetic nervous system dominates. Symptoms include hyperexcitability, restlessness, and an inability to focus, even while at rest or on your off day. Sleep is generally disturbed in sympathetic-dominant overtrained athletes, recovery slows, and the resting heart rate remains elevated. The body is reacting to a chronically stressful situation by heightening the sympathetic stress system’s activity levels. Most people who overtrain will see their sympathetic nervous system afflicted, simply because they lean toward the high-intensity, power, strength side.

You feel like crap the hours and days after a big workout.

   Once you get into the swing of things, one of the great benefits of exercise is the post-workout feeling of wellness. You’ve got the big, immediate, heady rush of endorphins during and right after a session, followed by that luxurious, warm glow that infuses your mind and body for hours. It’s the best feeling, isn’t it? We all love it. What if that glow never comes, though? What if instead of feeling energetic and enriched after a workout, you feel sketchy and uncomfortable? As I said before, post-workout DOMS is completely normal, but feeling like death  is not. Exercise generally elevates mood; if it’s having a negative effect on your mood, it’s probably too much
