23:1 Rule.

"It is a favorite belief of mine that no student ever attains very eminent success by simply doing what is required of him; it is the amount and excellence of what is over and above the required, that determines the greatness of ultimate distinction.", Educator Charles Kendall Adams. That is a fairly apt summation of the 23:1 rule. What are you doing outside of the gym to perform better inside the gym? 

I first heard of the 23:1 rule while attending my first CrossFit certification. The theory is that there are 24 hours in  a day. Most CrossFitters spend about one hour in the gym. That leaves 23 hours to screw up all the gains you made in that hour. It does no good to bust your tail in the gym and then go out and eat HoHo's (no matter how delicious they may be) and McDonald's for your meals.

If you know you have a weakness (like posture or adductors) work on that daily. My weakness is grip strength. I have a couple of choices on how to work this. I can either, 1) spend part of the "hour" (one my weightlifting days I might spend a lot more than one hour in the gym), or I can, 2) work on it throughout the day. I chose 2. I bought a grip device that I take to work and work on my grip strength throughout the day. Maybe your weakness is your posture. You can work that very easily. Sit up straight while you're at your desk. Don't have a desk job? Work on it while you drive (or commute if you don't drive). Don't make excuses not to, find reasons to. 

"Don't pray for an easy life. Work to be stronger men."
