"NextGym is a sophisticated wellness concept in a clean, secure, and convenient location. The Seca body scan provides the precise data needed to pinpoint specific recomposition goals, and I'm looking forward to integrating the state-of-the-art ARX machines. A truly top-tier addition to our city — thank you."
"As a senior with multiple medical issues, I was hesitant to start training. Madi put me at ease, making me comfortable with the program from day one. She became more than a trainer — a true mentor who motivated and encouraged me every step of the way. Her guidance helped me drop my golf scores from over 100 to the mid-80s in just one year, even winning my flight at Liberty Lake Golf Club. I no longer need to take ibuprofen for pain, thanks to improved flexibility and a pain-free swing. I have so much more energy for daily activities! Working with Madi has been a pleasure and has transformed my physical abilities. She's not just my trainer — she's now a friend."
"Before I started training with Madi, I was noticing lower back pain likely due to my scoliosis. Madi has helped me immensely by guiding me through workouts that both strengthen my core and improve overall mobility. She truly cares about her clients' goals and physical challenges. She is very attentive to the micro-adjustments that help you move more effectively. Her workouts are dynamic and target the entire body. It is wonderful to feel stronger and to have eliminated my back pain as a result."
"Madi has been my personal trainer since 2021. My fitness level continues to improve, along with my golf and tennis. Even more important, my overall health is better. Honestly, it is the best thing I can do for myself and my family!"
"I've been training with Madi since early 2022, and I wouldn't go with anyone else! She tailors every workout to my specific needs and makes them genuinely fun and engaging to complete. Thanks to her, my strength, flexibility, and overall health have improved dramatically. 10/10 highly recommend!"
"I started training with Madi in August 2020. As an older out-of-shape adult, I appreciated how she crafted workouts to match my current level while gently pushing me to improve. Although the training is golf-focused, the emphasis on strength, flexibility, and balance has improved my overall health. I now approach shots with much more confidence, and my husband has even remarked that my swing looks noticeably more athletic — encouraging me to keep going. I truly look forward to every session, excited for the next milestone!"
