"CrossFit is a strength and conditioning brand that combines weightlifting, sprinting, gymnastics, powerlifting, kettlebell training, plyometrics, rowing, and medicine ball training.
CrossFit contends that a healthy, fit person requires proficiency in each of ten general physical skills: cardiovascular/respiratory endurance, stamina, strength, flexibility, power, speed, agility, balance, coordination, and accuracy.
It defines fitness as increased work capacity across all these domains and says its program achieves this by provoking neurologic and hormonal adaptations across all metabolic pathways.
CrossFit athletes run, row, jump rope, climb rope and carry odd objects. They frequently move large loads quickly over short distances, and use powerlifting and Olympic weightlifting techniques.
CrossFit athletes also use dumbbells, gymnastics rings, pull-up bars, kettlebells, and many bodyweight exercises.
CrossFit is used in nearly 2,000 gyms worldwide and by many fire departments, law enforcement agencies, and military organizations including the Canadian Forces, and the Royal Danish Life Guards"
So that's the wiki definition.
Serious strength training that is the hardest thing I've ever attempted to do. And the days when I complete a full workout, I feel like I'm 10 feet tall.
It's that good.
In fact, I wrote about it in the following articles.
Currently, I am working on returning to CrossFit. I took a break from everything, including running, for a couple of years and lost all the strength gains. I'm slowly buidling a base of strength training and running consistently. My ultimate goal is to join my CrossFit gym by fall of 2020.
