A couple of weeks ago, I had the chance to go and talk to a knowledgeable coach. He was explaining to us how imporant it was to know our Back Squat as that we can tell you more or less the weights for other lifts. I have never heard of this before so I was very interested in this knowledge and wrote as much as I could down. Now, this is only for my benefit and reference.
For reference purposes: I was about 115 lbs when I last maxed out my back squat. I could be heavier now, but I don't own a scale.
Back Squat: 165 lbs (Dec 13, 2012)
Deadlift: 125% of Back Squat
Front Squat: 85-90% of Back Squat
Power Clean: 70-75 % of Back Squat
Overhead Squat (OHS): 65-70% of Back Squat
Snatch: 90-100% of OHS
Bench Press: 50% of Back Squat (truth is, I got lost writing it all down)
According to those percentages. I should have the following numbers, minimum
Deadlift: 206 lbs
Front Squat: 140 lbs
Power Clean: 115 lbs
OHS: 107 lbs
Snatch: 96 lbs
Bench Press: 82 lbs
Now, the coach did mention the Snatch but the truth I couldn't remember. I know that he said something along the lines of not snatching more than you can overhead squat, which makes complete sense.
Once you have the numbers, you can see where you fall short and work on those areas that need work. I know for sure that I need to work on my OHS and the Snatch. Both of which, I suck at.
