I almost couldn't get out of bed this morning.  Been exercising (gym workout in the mornings) for two weeks now and riding almost every day.  My 'bent muscles are seeming to get weaker by the day.  I never experienced this on my other bikes.  Anyone else go through this?  My legs aren't sore (like after working at tree climbing or something else that you don't do often), but just fatigued.  It seems I couldn't peddle today if I wanted to.  I also slept harder than I've done in a long while.  Seems like I've heard exercise helps out with all this fatigue stuff, but now I feel not as good as I used to.  I'll probably try and get in a few miles around the neighborhood this afternoon, but I'm not on the bike for a commute today.

Ah yes...recovery Thanks Greg.  Coke and a Reeses on order!  
 
Taking a day of rest to see what happens, still looking forward to the ride with the kids later.

S T R E T C H those legs!
 
Lots of riding at first needs to be balanced with some simple stretch & hold for a minute or so.
 
Potassium (bananas) helps too.
