Strong is Happy™
While the title of this brief post is a reference to Eleiko's signature motto, what I want to talk about is the fact that you are training because you enjoy training. You find training valuable for one or many reasons, including the fact that you like feeling accomplished, setting and reaching goals, and staying fit. You may have developed a group of friends centered around fitness in the real world or online that you can share your thoughts and feelings, and have a sense of community with. You may be training for purely aesthetic reasons with little regard to the underpinnings of what that training looks like. You are simply end-goal driven.
To continue, reasons for getting into fitness (which I use to collectively sum crossfit, bodybuilding, powerlifting, weightlifting, and other barbell/gym sports) are increasingly about a sense of community and shared accomplishment, and less about 5% bodyfat. I made the switch from bodybuilding to powerlifting largely because friends of mine were doing the same, and because I saw how much fun they were having, and I wanted to be a part of that. There's social pressure to follow the norms that people around you are participating in, whether you realize it or not. If all your friends decided gradually to become crossfit athletes, you would be hard-pressed to retain your individuality and stick with your sport of choice. We desire social bonds, and these occur over shared interests.
Mainly, I'd like to remind you that training is FUN. I go to the gym and lift because I love lifting, and too often this gets lost in the details. It should be a joy to step in the gym, and if it isn't, some piece is missing. Maybe you just need to remind yourself why you're there in the first place, or maybe you need to put on your favorite song and do exactly what it is that makes you happy. There is a place for detailed programming and sweating over what exactly to do in the gym but at the end of the day, you need to enjoy what you are doing! Life is too short. I would love to see more videos and comments to the effect of saying, "I had a fucking AWESOME time in the gym today, regardless of any PRs I may or may not have set."
In conclusion, happiness in training is not only about PRs. Its about embracing the process, enjoying the journey, the camaraderie among friends with shared interests, and the pure bliss of lifting!
