CrossFit is a radically different approach to working out. Take everything that you have ever been taught about lifting weights and toss it out the door. CrossFit is the opposite. If you go to a gym anywhere in the world, you will see thousands of people doing the exact same thing, and who despite having a million different reasons for training, will be doing almost the exact same routine. They will be doing the same 15 exercises, broken up into a 2 or 3 day plan, and they will inevitably be doing 3-4 sets, of 8-12 reps. During an average gym workout that lasts an hour, they will spend Less than 15 minutes actually "working out."
CrossFit forces you to do dynamic exercises that blend power, speed, agility, balance, hand-eye coordination, and body manipulation all at once. Think about it. When you're on the fireline, what are you doing? You're moving fast, you're slamming line with a pulaski, you're cutting down trees with a chainsaw, dragging swamp into the green, humping a pack over broken ground, hauling hoses around the forest, and a million other tasks. How are 3 sets of 10 reps on the Bench going to improve your ability to do that? It's not.
The Bench Press is arguably the most widely practiced lift - but why? No good reason. It helps isolate and develop your pectoral muscles. It's assumed its status as the lift to do most likely because it's helped generations of dudes fill out a shirt better. Nevertheless, thousands of firefighters mindlessly incorporate the bench press into their routine, for no other reason than they've been bench pressing since they played high school football. The bench press isn't the problem. If you want to isolate and develop your chest - it's a great lift. What CrossFit (and HF) finds fault with is a narrow-minded, one-track approach to fitness. Advocates of CrossFit define "being in shape" as being capable of performing a wide variety of athletic movements at a superior level. They do not consider lifting a ridiculous amount of weight 12 inches off your chest once as a valid measurement of fitness. If that argument rings true with you, you'll probably love CrossFit.
