Try three squat workouts a week. The first will be heavy, the second will be light, the third will be hell. Your first workout should be (after warm up) sets of 10,8,6,4,2,12 going balls to the wall on each set,taking as much time between sets as you need. Your second workout should be 5 sets of 15 reps with the same weight with only 30-45 seconds rest in between. This is much more difficult than it sounds. The weight should be relatively light, allowing you to get all your reps. But don't be a pussy: Push yourself. The last workout of the week is one set for 20 reps. Warm up, Pick a weight that you would normally do for 10reps, but do 20. It may take five minutes to finish your set but don't quit. Keep adding weight to your set of 20 every week. If you follow this routine for at least 4weeks, preferably 8weeks, I promise you'll be able to smash any goal you've set for yourself. It won't be easy, but it will be worth it when you're pushing everyone else around in the fall.
