In fairness, someone did recently beat Crain's squat, so if I manage to beat it, it would only be an American Record at this point and not an all-time record, but still, it's a big goal of mine.
My biggest philosophy is build up your body to handle heavy, high frequency squatting. I think that's the best way to improve overall strength. The squat skyrockets from that type of training and the deadlift generally comes along for the ride. I've found that focusing on the squat the majority of the time and then, for short cycles, reducing the frequency and adding in a deadlift day is the best way for me to make progress.
If you've got any other questions feel free to fire away.
