Despite what some less educated people say about CrossFit, Crossfitdoea not cause injuries and it is one of the safest types of physical conditioning programs around. Everyone gets niggles, you can get a niggle sleeping incorrect but I'm talking INJURIES.
If you listen to your trainer, take advice and watch others (for good and bad points) there is very little chance you'll sustain an injury. Knees over toes, high elbows, chest up and back straight are not said because the trainer likes listening to his/her voice. They are cues and reminders that try to get you to maintain good form even when tired.
At CrossFit Norwest we are proud to have one of the lowest injury rates in Western Sydney, in fact Sydney and sure the nation. Compare stats between that and your average commercial gym and you'll see what im talking about!
Yoy can do your best to stop injuries but if you are continually pushing the red line, always going 100% and maybe slightly over 100%, if you are heading to that place that you've never been to before to often then you'll get injured. Kiara doing heavy snatch and maybe to many of them. Rob with his shoulder and now his foot. Too much too often and you'll end up broken.
If you do break then we need to fix you ASAP. This means ice, rest the injured part, physio, Chiro, doctor or other health care professional. This does not mean do not train!!! CrossFit is scalable and as you have seen at Norwest you can get even fitter whilst being injured. Kiara ran a 25min 5km with thedog and Rob deadlifted 255kg after a shoulder reco. Look after your injuries
