Sobriety Through Fitness | Fitness and Addiction Recovery


The Barbell Saves Project is a 501(c)(3) non-profit with a clear and simple focus, support the well-being of individuals in recovery from substance use through using a community-based exercise program. We believe strongly that by building a strong, positive, sober community around people in recovery, we can increase the overall well-being of every person involved. Engaging in exercise classes can be both cost-prohibitive and intimidating for some, we want to remove those barriers, to bolster success and long-term sobriety. Participants will forge connections with each other and support a sober lifestyle. Peer support and encouragement is a foundation to our approach and is guided by coaches who are also in recovery. Additionally, we will focus on positive nutrition changes for members to further enhance their well-being.

The Barbell Saves Project offers an inclusive environment that celebrates individuals from marginalized and highly stigmatized groups in recovery from substance use disorder. We welcome individuals of all physical ability and body types. We continue to learn, grow, and improve as an organization to be increasingly just, equitable, diverse, and inclusive.

Coaching Staff

Tammi Saunders

Tammi’s love of fitness began in 2013. After a long hiatus from exercise and healthy things, she began working out in a CrossFit gym a few days a week. At the time, she smoked heavily, was extremely unfit, and wasn’t even sure she was going to stick it out. She shares that back then, she couldn’t do a single pull-up, push-up , or run 200 meters without having to stop. By the end of her first year she was attending class regularly and not only was she getting stronger, faster, and fitter, she was getting mentally tougher. She began to look at life in a different way, she developed a new mindset. She got comfortable being uncomfortable and adopted a “do hard shit” mentality, which translated into every area of her life. In 2018 Tammi took her passion for fitness full circle and became a CrossFit Level-1 trainer. She has never forgotten what it’s like to be new, unsure, and apprehensive, and she has a knack for making people feel welcome and at ease. Tammi is extra good at “aggressively encouraging” everyone. Tammi has experience as a high school life coach, working with at risk students, and a domestic violence victims advocate. In both roles Tammi developed and crafted her ability to build relationships, connect clients to resources and to help clients learn to advocate for themselves . Building trust through compassion and a natural empathetic way, and connecting with others is her strong suit. If you see Tammi outside the gym she is most likely looking for the best protein pancakes in the valley.

As a young teenager he became addicted to opiates along with drinking, and soon enough gang activity. Over the years he had ups and downs but his life eventually came crashing down and he hit a rock bottom. By then, he was a father to a six-year-old girl and was not able to feed himself, let alone take care of her. At the age of 29 he decided to check into rehab and get his life together. Since then, he has and continues to work hard in many aspects, especially to have an amazing relationship with his family and most importantly his daughter. Fitness and recovery have been a major part of his life, he believes “the two go hand and hand and have been my saving grace”. David said “when I found the Barbell Saves Project, I knew instantly this was my new home. Between helping others and having the opportunity to share my passion with others in sobriety, I’m excited to see where Barbells takes us in this journey.
