Back Squat

Last night we did eight rounds of 3 back squats. I did a bonus ninth set of 1 rep with 80 kilos. At 176 pounds this is a new max. I should have tried one more at 85 kilos. I felt like I still had something left, and I just found out my old max was 175 pounds back in December 2004 at another gym. If I had known that last night, I would have tried again for sure.
