I was having aches and pains from sitting all day and so I was nervous to do my normal 5x5 on squats. Last week I completed it at 140lb. Just these lightweight box squats did me in. I was in total cramp mode by the time I finished the split squats so I just went and hung from the table and did some light swings and back raises. It's definitely the low weight/high rep combo that kills me. It just puts too much strain on my hips/back and I realize that sounds weird. But for my body, heavy weight and low rep is much easier to accomplish. I should have just done my regular program and I think it would have been OK. Even if I didn't add any weight and just kept it at 140lb. 
The frustrating part is knowing that my legs are more than strong enough to get that weight up, it just this weak back of mine that complicates the issue. But if I've learned anything, it's knowing when to stop. If I had continued to push through that cramping I know I would have really set myself back with major muscle spasms and that would have pissed me off royally. So I stopped and now I live to fight another day. I'm still sore and now sitting again for 8 hours isn't going to help matters either. 
At least I know now that high rep stuff (on certain parts of my body) are out for the time being. Maybe as I get stronger I can change that, but maybe it's something that's always going to be this way and maybe it's something I just need to work around. It's not going to be anything that I'll allow to stop me though.
