"I am a 53 year old woman with many chronic illnesses. When I was younger I was very active –at the gym, social gatherings, loved life and myself. As we all encounter things in our life that sometimes set us back that is what happened. I was diagnosed with Systemic Lupus which is an over active immune system causing other problems to develop such as Arthritis which I developed. I began isolating myself, not exercising, poor eating habits and resorted to unhealthy lifestyle p...atterns. I was rushed to hospital with a” Stroke-like condition secondary to the Lupus and then with my knee surgeon telling me my knees were bone on bone but before I could get the surgery I needed to lose weight positive recovery and get to exercising cause my muscles were atrophied. WOW what an eye opener. I decided I needed to change. Started to change my diet and eliminated all unhealthy foods but did not starve myself. I lost the 54 pounds and had the knee surgery. I now wanted to exercise get myself in shape. I saw an ad for 19125 Bootcamp at Samuelson. I remember walking in the field seeing all these young people. I said to myself “what are you doing here? My answer to myself what do you have to lose if you don’t get yourself together your life. Don’t sell yourself short you are a fighter.” So I took the class and after spoke with the trainer Donnie Welte he was so genuine and so knowledgeable. Well, that was the start of my life changing journey. I am not going to say it is easy there are times I get frustrated with myself at times for not being perfect in my eyes. I begin to cry and Donnie takes the time to help me process these inner demons so they do not sabotage my success in this journey. I don’t know where I would be without Donnie. I hate to even think. Training with him has become part of my healthy lifestyle choices. He has truly saved my life and made me a better person inside and out. Thank you for always being there and for being in my corner and having my back!" -Francine

"I started working out with Donnie about 2 years ago, I did it for myself because I wasn't happy with the way I looked. It was extremely hard for me bc I haven't been active in about 7 years. During my first work out I cried and wanted to quit, Donnie walked me out after my work out and made me promise I wouldn't quit, in return he told me he would never give up on me! We both kept up our end of the deal. I still work out with Donnie, and I still cry, I can't do everything p...erfectly but I have made so much progress. I've lost 55 pounds, I ran an 8K and I love lifting things up and putting them down!! I still have goals I would like to reach like losing 30 more pounds and being able to do one single pull up, I know if I stay committed I'll be able to hit these goals too. I am so grateful to Donnie he says I do the work but I know I wouldn't do it without him!" -Courtney

"I have played sports and been active my whole life. I stopped playing sports when I graduated college almost 8 😭 years ago. Since then, I have tried many things, planet fitness, kickboxing, running - but stuck with none. I got bored. It was the same thing ... everyday.

I went to the grand opening at Donnie's new gym November 2015. I was inspired. I saw people who have been working out with him and had great results. I wanted that. I changed my mind of wanting to be "skinny" to wanting to be fit.

I started going to 19125 Fitness soon after (December 2015). I started 2-3 times a week because I didn't want to set myself up to fail .... again. My initial goal was to have back muscles!! After only a few months, my passion for working out grew. It became such an important part of my life, especially while trying to set a good example for my children.

Donnie is knowledgeable, motivating and pushes you to your limits. He knows what you are capable of and will not give up on you. The environment is empowering. The workouts diverse. The clientele inspiring. I look forward to seeing my morning workout crew everyday! I am so happy I decided to change my lifestyle and have Donnie by my side through the process!" Jenn
