JK-47. Interesting stats !
Welcome to the average american male.
Not bashing your numbers, but the fact that most of my male clientelle can bench a lot more than they can Squat and Deadlift.
Remember being young and all you did was Bench and Curl ? Well, welcome to the typical american male !
If you take the time and program properly, you will be able to put on 30# on your squat and dead over the course of a year.
Use something like wendlers 5/3/1 , Rippatoes Starting Strength, Stronglifts 5x5 ...basically something to get you a bit more balance out.
Your body will thank you for that...
Good luck and much success !
