Bad news and ok news

I started back at the gym Sunday went well... Until Monday where upon lifting a barbell off the ground. I felt my back go funny.... Dropped barbell. Agh... I must have been lifting it funny... This time last year I hurt my back it went into spasm....I guess this is a weak point... This also happened after squats. The physio said it was tight hamstrings....This time it was utter.....******.......At least I have learnt this time no more barbells only machine or dumbells. So Im gonna stay out of the gym for at least two weeks. Watch my food....See how my back works out and start again.....Weight in day tomorrow. My back is getting better so....Fingers crossed The weigh in day is tomorrow....
