Once you’ve found a gym that fits what you’re looking for and has great coaching, make the most of your time as a “newbie”. The competitor in you may be telling you to lift more than you should and push harder than you’re ready for, but it’s not worth it. Take the first several months of your time in CrossFit and commit to learning sound technique and movement. Once you’ve mastered the movements, then you can begin to layer in intensity and push yourself. This will not only benefit you in the short term by keeping you healthy and injury-free, but also in the long term by giving you a really solid foundation to build from.
