My lower back is screwed up, mostly around the SI area. I think I did it with the 1 & 1/2 squats. When I shifted into an RDL/GM position on the half reps I may have overloaded the area and I’m paying for it now. It may have also been from the sprints, but I wouldn’t count on it.
Other than my back, I’m sore in some places I haven’t felt for a while. Sprinting was rough, especially since I gained so much weight and didn’t even try to ease my way into it. It’s always like that after a layoff though, and my back never suffers, so I’m going to place the blame on the squats. I’ll have to watch out next time around.
