The 10 Biggest Mistakes in Fitness That No One Is Talking About

This article is part of the CrossFit BC journal, written by the coaching staff who run our classes in Olympic Village, Vancouver. We publish what we teach on the floor: training decisions, recovery, nutrition, and the honest tradeoffs behind them.

Common questions

What are the most common mistakes people make in fitness?

The loudest mistakes get all the attention: skipping workouts, eating poorly, not pushing hard enough. The quieter and more damaging ones are chasing intensity over consistency, training from guilt instead of intention, expecting motivation to do the work, ignoring recovery, and trying to do it all alone. Those are the patterns that actually stall progress.

Why do so many people struggle to stay consistent with exercise?

Because most people are using a fitness model built around motivation, intensity, and willpower, none of which are reliable. Consistency is built on a program that fits your real life, support that holds you accountable when you wobble, and a clear sense of why you're doing it. Take any of those away and the wheels eventually come off.

Is working out harder always better?

No. Harder workouts can absolutely have a place, but more is not the same as better. After a certain point, extra volume just adds fatigue without adding progress, especially without enough sleep and recovery. The athletes who stay healthy for decades are the ones who train smart, not just hard.
