I did an intense ab workout on Monday which included Crunches, Leg lifts, Side bends and Swiss ball crunches.
Tues,Wed and toaday I have a terrible pain in my back between my shoulder blades. Feels like I stressed my spine or something. Advil seems to help. It's just so weird because I do these type of ab excersises frequently.
This ever happen to anyone else?
How long should I take off of weight training? Any stretches ?
