5. I WILL HAVE TO TRAIN FULL TIME TO MAKE IMPROVEMENTS
Crossfit workouts and training programs can be scaled to suit any fitness level or schedule. They are designed in this way. We all lead different lives and the modern world is a busy place, so you will train as much or as little as you want to. If you are able to dedicate more time, train consistently and eat well, then you will see quicker progress than if you train once or twice a week, but in terms of exercise, a little is always better than nothing, and you can still make improvements.
If you want to be a professional Crossfit athlete then yes, you will have to train full time, but for everyone else, we have a bit more flexibility.
