To Rx or to not Rx?

That is the question! But first things first: what does Rx even mean?

Rx is a term thrown around in the CrossFit world that actually comes from the medical field; it means a medical prescription. When it comes to WOD’s, it is applied as the prescribed weight or movement. In other words, in order for your workout to be considered “Rx”, the WOD must be performed with the exact movements, exact amount of reps, and exact amount of weight without making any modifications of your own. So let’s pretend our workout of the day is Chelsea: 5 pull ups, 10 push-ups and 15 squats every minute on the minute for 30 minutes. If you use a band for assisted pull ups or perform a push-up on your knees, you are no longer “Rxing” the WOD.

With the definition in mind we also need to understand that it is perfectly okay and encouraged to modify a movement, reps, or weight in order to accommodate to what our bodies can perform. There is absolutely no shame in not being able to do a proper push-up (yet!) or needing a little assistance on pull ups. Remember: good form and proper technique is always the number one priority. So the question at hand is whether or not we should attempt to Rx a WOD.  And the answer is not always.

While one of the main focuses of our community is to push ourselves and be better than we were the day before, the most important thing is always going to be listening to our bodies and knowing realistically where we stand on what we can perform. It is extremely important to never compromise ourselves or put ourselves in harm’s way- don’t give into your ego! When injuries occur we’re hurting our bodies and keeping ourselves out of the gym for a few days, weeks, or even months, depending on the severity of the injury which has now created a domino effect and may compromise our progress.  

So, if you are ever unsure of whether or not the task at hand should be performed at Rx weight or movement, please consult with a coach and perform enough practice reps for you to be 100% sure you are where you need to be.
