"You’ve got to drive the body to the last inch of energy then go on! You gain nothing by just going up to where your body says you’re tired. The body will build and grow only to fit the demands the mind makes upon the lazy body. If all you do is exercise until the body is tired, the body will get lazy and stop a bit shorter every time. You must go to the point of exhaustion, then go on. That way the body figures out, “We’ve got to build up more strength if that crazy mind is going to drive this hard!” If you always quit when you are merely tired, you will never gain. Once you let the body tell the mind when to quit, you are whipped for sure. You can not gain by listening to the body. We can become much stronger if we drive the body. We use about on-tenth of the available strength of our bodies and less than that of our minds."

WOD
21-15-9 reps for time:
Back Squat (225/155)
Strict Pullups
GH Situps

All you have to be able to do is seven squats, seven strict pullups, and seven gh situps when deciding whether to do the prescribed workout. Our goal is to get you to prescribed weights as soon as possible. You may not be there yet but during workouts such as these you should pick the heaviest weights you can handle while not compromising technique/safety. On the same token you can't be afraid to lose the weight on the safety catches on the squat racks (that's what they are there for).
