I have a history of back problems. Surgery,epidural shots,therapy,lifetime use of pain killers. Anyways my back flared up about 8 months ago. I quit working out. I recently started lifting again. Holy shit I have never been this weak in my life. I still don't have the drive to get built again and my back still hurts everyday. Anyone have any tips or recommendations. I just turned 42 and it is depressing that I lost 15 years of training in 8 months.
