A twinge of pain, is just the beginning. Its your body telling you something. Listen to it! There is a difference in muscle fatigue and pain.

Almost a year ago I threw my back into massive muscle spasms. I’ve been doing well but as soon as I feel that twinge, I quit. I can say that I think its related to my hamstrings. When they are tight my back seems to have issues. So, tonight I was supposed to do core 20 with turbo fire, and it hurt. So I stopped. Now my back feels like its about to go into spasm. So I’m being super careful this evening and I will probably rest tomorrow. Better safe than sorry!

One bad workout will put you out for weeks.
