My copy of Infinite Intensity came today. But heres the catch (there always seems to be one). My lower back felt sore Friday night at work and when i woke up Saturday morning i could barely get out of bed. its been sore all weekend and still doesnt feel 100%. If it didnt have to lift boxes at work i could just avoid exercises that strain it, but obv i have to go to work. I dont know what they will say at work cuz this is the same thing that happened a few months ago.
