It’s impossible for me to discuss mindset without talking about hellacious practice and training sessions. Times when we couldn’t carry ourselves off the mat or out of the ring after practice. Times when we collapsed trying to walk to our car after a conditioning session. Or those times when we slept in our car because the thought of walking up the steps to get into our house where we would have to walk up another flight of stairs to get to the shower was just a miserable thought.
We learn mindset by pushing ourselves to the breaking point physically. Pushing those edges is where we learn our mind is much more powerful than our body. The mind drives the body beyond perceived thresholds. Then we do it again, and push even farther.
Is it necessary to train and practice at that level every time? No.
Is it necessary to have trained and practiced at that level for a time? Yes.
Have a listen to Josh Hinger at the 8 minute mark in this video talk about the mindset of a champion, and the training intensity that this mindset brings to each session.
Then get some and go again.
