If your looking for a gym that will motivate and push you to your highest potential Underlying Strength is the place! The workouts are challenging but fun with fellow members that are inspiring. I look forward to seeing coach Brenner and Vicki at 7 am to kick start my day in the right direction. Coach Brenner has perfected the craft of both fitness coach and comedian who can make the most challenging workout entertaining. Coach Vicki loves to start off class with fun partner warm ups that actually helps form member friendships that have inspired me to push harder in class. Best coaches who give hands on instant feedback and adjustments during the workouts and just the right amount of encouragement. The atmosphere is awesome. You will not do the same workout twice and if you go you will see the results no question. It’s a life changing gym experience and I recommend it highly to all looking for a gym to call home.

I 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.

I joined Underline Strength just after moving into this area, and that's one of the greatest decisions I have taken. Coaches invest time to schedule exercise daily to maximize the benefit of the members. The place is very welcoming. The members and coaches are very supportive. As per my schedule, I mostly work out with coach Brenner, he is a brilliant coach!!! I have worked with all the other coaches also - Sid (owner), Danielle and Vicky and they are great.

Underlying Strength has become a second family for me. The instructors are motivating, thorough, and good for all levels. The clientele is super supportive. As someone who isn’t the biggest or strongest, I never feel intimidated. Everyone is so nice and signing up for this gym has been a highlight of mine of the past couple years. Highly recommend!

I had the privilege of joining US in January and I did small group with the amazing human that is Coach Brenner. He guided me and helped me every time i was in class. Coach Brenner is the best hype man any human can ask for. He made me fall in love with lifting. I love the US family. What makes US special is it makes the members feel welcome, coaches are there for you. Group classes are so much fun. If you’re not sure what you want try small group it more 1 on 1 with the coaches. Continue the amazing work that you do underlying strength 🫶🏽
