To All who have replied, thank you for all of your responses.  I just want to clarify one thing.  I haven't been working out for only 2 months.  I'm 33 years old and I have been working out on and off since I was 14 years old.  I used to lift heavy and hard in my early 20's which most likely was not a good idea since I now have a bone spur in my right shoulder because of it.  I stopped working out for about 3 years after having 2 kids.  Which was a huge mistake, really let myself go!  For the past 2 years, I have been exercising again.  I took the summer off because it's the summer and it always happens to me vacations, going to the beach etc.  I need to learn to keep it up in the summer and NOT stop.  But anyways, I started exercising again for the last 2 months and then the back pain hit me.  I believe it is from the insanity work outs since they have you jumping around and I'm not used to that.  What I plan on doing is resting for the rest of the week and keep taking Motrin.  I will start again this weekend and I will work on strengthening my lower back and abs.  I'll start with walking on an incline instead of jogging and ease my way to running again like I was.  Lift weights and not to heavy.  I'm going to buy Ostarine from pureessence and do a 6 week cycle.  I took ostarine last year in the winter and I LOVED IT!!
