★ 5★ 4★ 3★ 2★ 1The absolute best gym you can find. You’re guaranteed a great workout whether it’s fit camp or small group. You will always see results when you’re consistent and will meet great people too. Sid is the best!! More than just a gym
August 11 · Sarah GallagherI joined when I was at an all time low, no matter how hard the battle was day to day I showed and the members and coaches made me feel safe, loved and heard! I felt at home! I found my happy home.. I was also at my heaviest and with guidance and encouragement I dropped 20 pounds in a short 6 months.. I’ve never felt so good about myself and the accomplishments I’ve achieved. The staff are and will become family.. Recommend this gym a thousand times over and over again!
February 24 · Jamie SantosWhen I went to Underlying Strength I was suffering from stiffness, lack of energy, asthma, and a significant weight program. The trainers took their time and walked me through the process getting back to health by educating me and encouraging me throughout my journey. Today I am a different person and soon, with the help of them, I will achieve all my goals. thank you Syd, Vickie, Brennen, and Danielle for all your work.
December 13 · Joel GruenkeI have been a member of Underlying Strength since 2022 and I cannot say enough good things about this gym! After a long day it work, I look forward to the hour I get to go to a group fitness class the most. There is an unwavering sense of community here — every person I have met here is undoubtedly among the most supportive people I've encountered, and I can confidently say it feels like you're part of a family. All of the trainers are incredible. They are invested in all aspects of your growth and I hope they know that their impact goes far beyond just fitness. I have joined and tried many gyms, but nothing has come close what you find at Underlying Strength. This is the place if you are looking for a gym that challenges you, encourages you, and celebrates you both in and out of the gym.
December 13 · Madi B.Best gym in the area! I tried for years to get a solid routine down going to a regular gym like Planet Fitness, and never could hold myself accountable and also never felt like I was actually learning anything about fitness and my body. Ever since I started training here, I have learned workouts that work well, how far I can push myself, and I am actually excited to work out each day. I have had many friends start coming with me who also love it and have converted their gyms as well. It is THE REAL judgment free zone, not just a marketing scam like Planet Fitness claims. Class times are convenient and every single person is welcoming and accepting given everyone is on different levels and body shapes.
