Yesterday was my squats and deadlifts day. I'm on cycle and I have been doing 7 sets of 10 reps on each and raising it 5 kg each week for the last 6 weeks. Well, yesterday my lower back was absolutely fucking killing me with tightness during the squats. I had to stretch it twice but it just never got back to normal. Then when it came time to do deads I could only finish 3 out of the 7 sets. Can I get some insight into this? Should I lay off the deadlifts for a while? Is it wrong that I feel back pain during squats? Like wrong form? Should I not do squats and deads on the same day?
