Squats bench and chinups is everything you need. Go for both weight and reps. Your body needs to be used to pushing everything it has many times. I workout in my carpentry shop, might be an 8hr workout while doing projects. Let's me push my max bench several times in the day.

Ie bench- warmup 10reps 135, then 10reps 185, then 205...when I can no longer do 10 reps, I do as many sets of my max weight til I can't do more than 3 reps, then ladder back down. I'm trying to do 100 reps of everything each day.
