“The greatest adaptation in CrossFit is of the mind.” -Greg Glassman
CrossFit is so physical. We push our bodies to the limit. Everyday we ask more of ourselves. We hit the WOD, some strength before or after, practice some skills, then mobilize and feed our bodies so we can come back in and do it all over again. This is what CrossFit is between 3-6 days per week.
Read that quote again by CrossFit Founder Greg Glassman. How powerful and true it is. He first made that statement while he was still running the CrossFit Level 1 Seminars around 2004. He and Greg Amundson (CrossFit Amundson, CrossFit Goal Setting, and Santa Cruz Original Firebreather) were observing seminar participants attempt muscle ups. Two males went up for the first attempt ever. Male 1 nailed it. He came down and his buddies were all congratulating him. He responded with humility I knew that I could do it. Meanwhile, Male 2 failed and as his buddies came to offer condolences, he stated that it was ok and that he knew he wouldn’t do it.
You see, you will achieve what you believe. Of course you need to have the appropriate skills and strength. That being a given, your mind will determine the rest.
