CrossFit gyms use equipment from multiple disciplines, including barbells, dumbbells, gymnastics rings, pull-up bars, jump ropes, kettlebells, medicine balls, plyo boxes,[20] resistance bands, rowing machines, and various mats. CrossFit is focused on "constantly varied, high-intensity, functional movement,"[21] drawing on categories and exercises such as calisthenics,[22] Olympic-style weightlifting, powerlifting, Strongman-type events, plyometrics, body weight exercises, indoor rowing, aerobic exercise, running, and swimming.[23]
Here comes the tough love. This is for those of you who are considering taking on this life-changing month, but aren’t sure you can actually pull it off, cheat free, for a full 30 days. This is for the people who have tried this before, but who “slipped” or “fell off the wagon” or “just HAD to eat (fill in food here) because of this (fill in event here).” This is for you.
