Don wants his clients to get stronger. He has been coaching and teaching for over a decade. Don has a masters in chemistry with bachelors in chemistry and biology and teaches chemistry at Pima Community College. He coaches the basic barbell movements, with attention to form. Don loves strength training because:

  • It’s the fountain of youth. As muscles grow and joints bend, aches and pains melt away. Humans become more confident and independent. Training to be strong forces us to tune into our bodies.
  • It’s a journey of self-discovery. Clients learn to do the things that help them; they then help others because sacrifice and hardship builds character. Clients will learn interesting things about themselves, good and bad. They will decide what to bring and what to leave behind on this journey.
  • Clients get strong. It works. In weeks they can be stronger than their friends. In months, they can be the strongest people they have ever been. Strength helps everything: moving furniture, opening pickle jars, lifting grandkids and yes, spouses or significant others will notice the difference.
  • Community. Barbell people are the best people. They are humbled over and over again. They support one another with kindness and want others to grow with them.

Don began using barbells 20 years ago and continues. He uses them to give adults strength and confidence and to help young athletes defeat their opponents and achieve their goals.

For adults, the confidence built along a relatively short journey with barbells can be invigorating. In can help get their lives back and cope with hardship (divorce, death of a loved one, body weight). Barbell training can be a comforting and stable part of the week when waves of life crash over them.

For young men and women, formative years of confidence and character building will start them onto a pathway. Seeing this transformation as maturity doubles, overnight sometimes, can be amazing.
