A new squat PB!

Training at the town local gym with two friends, I was about halfway through my squat session when I thought '....I'm finding this unusually easy tonight.' I had been told by others at my powerlifting club that 'If you're strong use it,' as hey, we all have good days and bad days. So deciding to go for it, i put my current PB on the bar, 160kg. Easy. I felt like i couldve done 3 reps on it. So ecstatic, and pumped up, I put 170kg on the bar, grabbed a third person for spotting, and went for it. I couldn't believe myself how comfortable it felt! I was on top of the world for the next few hours! So here is hoping for the start of a move up in strength!
