"7 Hidden Signs of Overtraining" sparkpeople.com/resource/fi...
Worth a quick read through if you're feeling a bit worn out - it starts off by saying up to 90 minutes a day is fine, but further on, the signs of overtraining did ring a few bells with posts I've read in the last few days. Doesn't mean you have to stop, but maybe take a few minutes to stand back and consider whether easing off a bit (eg gentle yoga or walking) might be helpful. Then again, it might just be your body beginning to adapt - but if you've been wondering whether you might be thinking of dropping out (!), this might be helpful.
