Awesome, clean, space, and everyone is super friendly there. Unlike most fitness gyms, where none of the trainers smile and act like they're better than everyone else. I seriously feel super comfortable training here and even though it's not right around the corner from my home, it's well worth the drive. If you're a female, looking to get in shape and become more confident in your own skin, I highly recommend you see trainer Sarah! 👌 You won't be disappointed.
RF is an amazing gym to workout at. The staff are incredibly knowledgeable and you are sure to hit the goals that you want there. I would highly recommend this gym to anyone who wants reliable fitness advice and a great environment to workout at.
Sophie is the best! She took me on as a nervous newbie, and made me feel super comfortable and safe. She's helped me with achieving my goals and made me grow in my confidence. She is extremely knowledgeable, encouraging, and understanding. I can't say enough good things about her, and highly recommend training with her!
I’ve been going to Relentless for two years and have loved every minute. Josh runs a great facility and has built a strong community of trainers and clients. It’s low-key, inviting, and worth every penny. I owe so much to Emily and our workouts!
I’ve been coming to this gym for 3 years, I love it here. Everyone from the trainers to the clients are all so friendly, and it’s a great community. It’s always clean. The privacy of this gym is excellent for beginners or someone who is not sure what they are doing. I personally was intimidated by gyms, and because of coming here I’ve been able to hit significant goals of mine weight loss and strength wise. I’ve also met some of my closest friends here as a bonus. If you’re looking for a gym community that will push you to be your best, you won’t regret coming here.
