Dennis Wilson, Ed.D., head of the Department of Health and Human Performance at Auburn University in Alabama, suggests these methods. Check your habits. If you've answered yes to any of these, you've fallen into classic overtraining patterns and are probably pushing yourself too hard. Monitor your mood. The single best indicator of overtraining is an otherwise inexplicable plunge into the emotional toilet.
Mood often deteriorates before physical performance does.
Take your pulse. Overtraining typically makes your resting heart rate go up over time. To keep track of it, take your pulse in the morning before you get out of bed, counting the number of heartbeats in one minute. A persistent rise of the same amount over a period of weeks may indicate a problem. Maybe you're the kind of guy who likes working yourself hard every day.
