Here we are.

I play pre [and post-?] apocolyptic strength guide, writer, retired math teacher, and... I consider myself to be a mad scientist which was what I dreamed of when I was six or seven, I can't remember - don't wake me up. I am a curious kind of healer and a sheepdog and all kinds of other things also, sometimes wayyy too seriously; yet maybe just it plays "me" (David Butterworth). Like I said: Here we are. Sign up for private trips or RunWild events, you'll never again step in the same river. I offer tutoring service on the side, as well, more support for our family's adventures and so that we can eat delicious, nutrient-dense food. And I'm currently on a dive into what may become my next "career" (possibly). Isn't it wonderful, I mean... "to be alive"?!

Look, am I someone with extraordinary ability? Am I someone with extraordinary health? Probably not, rather just some bundle of electrons and cells and tissues and ??? that will never ever ever be the same "form" as it was even five seconds ago. Most of the time I call whatever this is that's happening, Zenso.

My history appears to be rich with crazy creatures like me who have no real idea about anything, but still wish to attend to the process and have fun... while building fine, usable asses (and dancing with the earth). Outcomes like personal growth, insight, ability, vibrancy, robust living, and sexy thinking may end up being part of the deal. And for hell's sake, none of this has anything to do with "cardio".

Zen? So the only zen you'll find here is what you come with - so quit looking.

David Butterworth has been a motivational and healthy addition to my life. Butter and I have had various training sessions together; Run Wild, Private Training, Testing online training and I have to say it has all been an incredible experience. Butter takes you as you are: mind, body, and soul and helps you be YOU! And at the end of the day that’s exactly what we each need. Thank you Butter!

I trained with Butter for 4 months (unfortunately had to stop when I moved for a job) however, it was the first time I could actually see results in my body. Not only did I see the physical changes but I felt better, more energized and by far much stronger! Training with Butter changed more than just my physical appearance, I learned to love getting up early and accomplishing so much before the rest of the world was awake! Even now, 36 months post move, I have yet to have a similar training experience.

Training with David, I felt I finally had the ability to tap into my inner athlete as he introduced me to a more dynamic way of training. The diversity of his training sessions coupled with his energy of presence allows you to get to know yourself every session and excel at whatever it is. Above all, it’s his positive direction and genuineness to see you for who you are that sets David apart from any other “trainer”.
