I spent a real long time warming up tonight. Including warm up sets I probably spent 40 minutes warming up. I used 185 this time because last time I used 175 and got 15 reps on the last set, so I thought a 10 lb jump was appropriate. On my last set tonight I got 15 reps again, and could have maybe gotten a few more. I guess I'll do another 10 lb jump next time. I think I've been underestimating my squat.
