The Science Behind the Magic of CrossFit

ByMariah Rose MooreJanuary 9, 2023

In CrossFit, we don’t get our results from a lab. Instead, the data that guides our training and nutrition recommendations is collected from countless workouts where time, weight, distance, and reps are measured.

The measurement and recording of workouts is part of our culture and makes CrossFit a giant, efficient experiment conducted in garages, affiliates, and parks all around the world.

Every recorded workout is a data point that contributes to the experiment. It is this measurable, observable, and repeatable data collected from tens of thousands of athletes that has allowed us to prove the value of intensity, functional movements, variance, and whole foods eaten in the proper amounts for optimizing fitness and health.

And most importantly, as best practices permeate the community, we learn and implement what really works for our athletes.

Experience the power of CrossFit for yourself.

Tracking workout parameters is extremely valuable from many point of views (feedback, motivation, fitness assessment etc) but this video has nothing to do with science or experiments.

There was nothing about science in this article. It will be good to put some numbers or results of some results on relation between crossfit workouts, long term retention rates, measurable impact on health, stamina and strength increase. Numbers, statistics, conclusions.

Question is fit for what?

 If your goal is general CrossFit yeah. CrossFit is the perfect method.

 If your goal is to excel as a competitor, not so.

 If your an individual athlete in any other sport (track, swimming etc) and took all the trainable elements and applied CrossFit methodology (constant variation etc) your progress would come to a grinding halt.

Periodizing intensity and training content is the magic needed for long term progress

This could have been a good title for a good article. Click bait, it was just an ad for the open. Too bad, lost opportunity.

I thought Nicole’s narration, soundtrack, & editing were on point. Nice short video that clearly tells people what CrossFit is about
