How about the bad days?

Some days just don't go well. The fact is that training has to be progressive in order to work, that means it gets harder and harder... the loads increase, the duration increases, the intensity increases. But you are standing there in your workout costume, trying to get your head correct, you bend over to grab some light bells and they seem like they are screwed to the floor!!  Oh Boy, now what?  You have specific numbers with much heavier bells to hit... it went well yesterday?? You haven't had one of these days in a long time?

At this point, you can only do 2 things that make sense. You can ignore the real signals that you are getting from your body and force yourself to make it do the work. Or you can intelligently read the signals and let go of your original plan,  take the pressure off yourself and have a "fun" session doing something light and enjoyable. I have done both, the second way is smarter. 

The real trick here is being able to recognize the difference between normal mental push-back, and legit signals of potential trouble.
