Keep it Simple
Since I'm easily susceptible to overthinking things, this phrase is something that I try to regularly keep in mind, especially when programming workouts and coaching our members. In the context of what we do in the gym, "keep it simple" is a helpful reminder that although technical barbell and gymnastics movements are great demonstrations of fitness and ability, they are not vital for being in shape.
Muscle-ups, heavy Snatches, handstand push-ups, etc., are all great goals to work towards and are great ways to mark advances, but it's important to keep in mind that they are nice-to-haves in the grand scheme of things. A good diet, some basic weight lifting, gymnastics, conditioning, and a regular plan for working out are all we really need to be in good shape.
I bring this up because technical movements are becoming more and more prevalent in the CrossFit world, and it's easy to get caught up in thinking that you need to be able to perform all these intricate maneuvers just to be in shape. You don't! Set them as goals and work towards them, but keep in mind that competency in the basics and an open-mindedness to proper scaling can go a looooong way.
If you're ever feeling overwhelmed with the workout because it lists movements you haven't quite achieved yet, or are thinking that you should just skip because you can't do what the workout recommends, remember that the shiny objects we see the Games athletes performing are something we can aspire to more than they are a necessity to be strong and capable.
Even the classic definition of CrossFit itself is pretty stripped down: constantly varied, high intensity, functional movement. Simple. Keep it simple!
