So this is an interesting topic for me. One thing I have noticed especially in Crossfit, is the emphasis on Mobility and Flexibility. It appears that Mobility & Flexibility is not just something you do if you are a little stiff, it is a key pillar of being decent at Crossfit. Both boxes I visit offer one session a week for an hour, dedicated to this subject, there is no WOD at the end, no sweat (except from the discomfort of some of the positions!) and no real test of physical challenge. Additional to that, every normal Crossfit class at our box consists of a warmup and, often, specific stretches to improve performance in the workout.
In a previous life, I did kickboxing and, given the dynamic movements required, the warmup and stretches were very general. Regardless of whether we were doing kicks, or self-defence, or sparring drills – the warm up was identical. As an instructor, we were taught to stick to the warmup routine and the stretches at the end. Looking back and knowing what I know now, I could have truly saved myself a lot of pain and suffering from stiff muscles if I had known how to do a proper warmup or cool down.
So my suggestion to everyone is go visit a Mobility & Flexibility class at your box or, sign up to ROMWOD, or just find some stretching routines on YouTube. Never underestimate the power of getting a good stretching session in – it might hurt a bit as you find particularly sore or tight places on your body, but afterwards, you will feel 100 times better.
