    From fat kid to Running Boston
    Russ Steinhorst

    Growing up I was the fat kid, and as I aged, I had a hard time finding my way in health and wellness. Since 2010 I’ve been working with members of the TNT team to improve my strength and wellness. During this time, I qualified for the Boston Marathon, completed Ironman Wisconsin and I feel stronger than ever! I am continually challenged by the team to reach new goals. Spend some time at TNT Fitness and you’ll quickly learn the team TRULY cares about YOU and YOUR individual goals! I encourage you to give TNT Fitness a try. Commit to the process and YOU WILL achieve your goals!

    I was tired, weak, and out of shape
    Todd Midtvedt

    I was tired, weak, and out of shape. As an on-the-go dad with 5 kids, I realized I desperately needed to change my lifestyle. The TNT Fitness team has helped me go from flab to fab and I’m happy to say I am no longer trying to keep up with my kids, they are trying to keep up with me. 

  • Dan and Terri Buboltz
    We started at TNT because we felt like we “had” to. Now the TNT experience is part of our lifestyle
    Dan and Terri Buboltz

    It was quick and easy to see that TNT was for ANYONE! As business professionals for the last 30 years, Dan and I hadn’t made health a priority. I was gaining weight at an uncomfortable rate and Dan was dealing with chronic back pain. What stands out about the TNT Fitness program is that each coach TRULY cares about you and YOUR goals. They’ll encourage and challenge you along the way, and we wouldn’t have it any other way! Since joining I am down 40 pounds and Dan has eliminated his chronic back pain, thanks TNT!

    Before TNT Fitness I had a difficult time finding this type of healthy
    Kelly B

    For most of my life, I’ve been on a journey to find healthy. Working with personal trainers, joining weight loss groups, and even trying a handful of fad-diets. I was getting frustrated because the results weren’t coming as quickly as hoped. Since working with TNT, I have learned what healthy is. They’ve taught me how to fuel my body for energy and weight loss, how to move with intention and purpose, and have helped me get stronger and feel better! The TNT team will encourage you and support you all along the way. I recommend TNT Fitness, without them my hard work would still leave me frustrated.

    I’m proud of the gains I made, but the environment and community have been the greatest reward.
    Jess Dennis

    I was initially intimidated with starting a whole new program. Prior to TNT, I had never used kettlebells for training and my knowledge of what you could do with them was extremely limited. The coaches at TNT helped me get comfortable quickly. While I’m proud of the gains I made so far, the environment and community has been the greatest reward so far.
