I was an aerobic junkie. For 20 years I swam biked and run my ass off (quite literally). For years I exercised 24 to 30 hours every week logging 15000 meters swimming, 300 miles bicycling, and 60 miles running. For twenty five years I have had the same New Year’s Resolution. “I want to be in better shape than last year”. I still have the same New Year’s Resolution, but how I go about achieving my fitness has changed.
As a professional firefighter I am an occupational athlete. My job/profession requires me to be “fit”. And I was exercising more (in time) than 99% of all firefighters in this jurisdiction. So why was I not in much better shape than everyone else when I was called upon to do my job?
Firefighting is demanding and strenuous work. When people take the entry level test to become a firefighter many exclaim that they like the idea of every call being different. It is ever changing. You can be just sitting down for a nice dinner at the firehouse and receive a call to respond to a medical emergency, or an automatic fire alarm, or a working structure fire with people trapped. Every response deserves your ability to handle the job required to help stabilize the problem. The ability to think clearly under stress is also critical and rarely trained. We can be at rest one minute and hand jacking 200’ of supply hose, lifting and throwing 35’ extension ladders, and pulling ceiling the next. An exercise program for “functional” fitness for a firefighter that bases its programming on monostructured metabolic conditioning (treadmill, rowing machine, or exercise bike) followed by unilateral strength movements like bench press, bicep curls, and seated rows is grossly inadequate for what the reality of firefighting requires of us.
I always viewed my V02 Max score as the gold standard for “fitness”. Maximum oxygen uptake is measured it is a barometer for how efficient your body is at transferring the oxygen that you breath into your blood stream to replenish your aerobic exercising muscles. It can be estimated by testing on a treadmill or ergometer by following your cardiac response when delivered an ever increasing load. How quickly your reach an estimated 85% MHR for your age. Or you can be tested by actually measuring 02 in and C02 out while exercising. 40 is the estimated minimum V02 for a firefighter to effectively do his job under extreme physical stress. Miguel Indurain the legendary Spaniard winner of the Tour De France touted an incredible 88 V02!! To increase your maximum oxygen uptake takes a very long time to train on or near that “anaerobic threshold”. And the increases come very slowly! Like I said earlier, my goal was to be more fit (a high V02 Max) every succeeding year. "An athlete diminished by excessive aerobic training is slow and weak. At CrossFit we call that state, 'spun-down.'"
Some years back I heard about CrossFit and some extreme workouts from a friend. I was intrigued enough to look at the www.crossfit.com website and consider the possibilities of attempting a workout. The first workout we attempted was “Cindy” (for 20 minutes complete as many rounds as possible of 5 pull ups, 10 pushups, and 15 body squats). I completed the workout with a weak result and I was hooked on the bodyweight style workouts. It did take me some time to become as sold on the Olympic style of lifting heavy things because I was not comfortable with doing those sorts of movements. So I would search the web for the bodyweight style WODs (Workouts of the Day) that I liked to do. In doing so I was missing a huge part of what CrossFit is all about. You should be training on all aspects of fitness. The fitter person is the person that can excel in more aspects of fitness than you. Not the person who can run the longer and fastest, or the one who can do the most pull ups, pushups and squats.
I often ask new folks that are coming in to CrossFit Orange County for the first time “In your opinion, ‘Who is the fittest person in the world?” 95% of the time the answer I hear is Lance Armstrong. If your standard for fittest person is the person that can ride his bicycle the fastest over a 2100 mile course for three weeks then you would be correct. As bicycle racers go, he is tops in my book! But as the fittest person in the world? No. Fitness incorporates more than cardio respiratory endurance.
10 General Physical Skills:
• Cardiovascular Endurance
• Stamina
• Strength
• Flexibility
• Power
• Speed
• Coordination
• Accuracy
• Agility
• Balance
CrossFit training specializes in NOT specializing. An elite fit person needs to be proficient in all of these aspects of fitness. You are only as fit as your weakest skill. If Lance Armstrong came into our gym for a workout and we were competing for the title Fittest for the day at CrossFit Orange County. Lance is going to pray for the workout to be a longer endurance style workout (like ride for bike for 150 miles over a huge mountain). The proficient athlete at many of these physical skills will be the overall more “fit” athlete than a sport specialist, even if they are the best in the world at his or her game. "There is no single sport or activity that trains for perfect fitness. True fitness requires a compromise in adaptation broader than the demands of most every sport."
