I would say that atleast 90% of people cheat on their first couple CrossFit workouts.
Sometimes they don’t want to feel exposed as “unfit”, sometimes they’re afraid to die (fair enough) and most of the time they just don’t understand how to perform the workout/movement properly yet.
However, after a few weeks or months, people get the hang of it. They also comprehend that if they want to get fit, they can’t half ass their workout. Not for any reason other than an injury or lack of mobility.
They are aware of the fact that they are doing this for themselves and nobody else.
