E.P.O.C - Why CrossFit Works!

Many of you have signed up for the I Am CrossFit - E.P.O.C challenge! Well, what is E.P.O.C and why is it important to you?

What is E.P.O.C?

E.P.O.C stands for Excess Post Exercise Oxygen Consumption and refers to the work your body continues to do AFTER your workout. During EPOC your body is restoring/repairing itself to its pre-exercise state. This means, you're continuing to expend energy and burn fuel (calories) at an elevated rate.

EPOC is higher with short, high intensity workouts (like your CrossFit Central WODs) than with aerobic (running, cycling, long slow distance) workouts.Why is it important to you?

EPOC is the reason CrossFit makes YOU fitter than you've ever been. You must attack every CrossFit WOD with your highest intensity and you will increase your metabolic efficiency. It's shown that EPOC can increase your metabolic rate 13% up to 3 hours after exercise and 4% after 16 hours post workout! That's right one 5-15 minutes workout can increase your metabolism for 16 hours. READ THAT AGAIN! That is exciting! That is something your 1 hour runs and 3 hour bike rides CANNOT do for you!

This also means that you need to respect the need for your body to repair itself after CrossFitWODs. You're in the challenge, you're working towards your goals, you're making sacrifices, and pushing yourself to new physical limits BUT make sure you rest and recover.


How has the first week been?

For me: I need to cut out the corn tortillas and get back to 1x a week alcohol treats! I am doing the I Am CrossFit workout today and will let you guys know how I did and what my goals are for the next 8 weeks.
