2 years ago, (I was 21 in FSU) my lifting partener and I did a squat a thon contest of who could do 315 for the most reps. He went first and did 30 full reps, I went after him and did 50 full reps. It was awesome and the entire gym loved to see two friends challenge each other like that. Now at 23 I don't go over 225 for 10-12 reps. If you have a regular lifting partener, try to challenge each other like that.
