This bootcamp gym has been such a great find! Everyday is a different workout, so they never get boring, and the number of class times offered each day makes it easy to stay consistent. Being open seven days a week is a huge plus. The staff is amazing -- always welcoming, super helpful, knowledgeable, and genuinely encouraging. No matter where you're at in your fitness journey, you feel supported here. The owner is also fantastic and clearly cares about health and fitness. Instead of being outrageously priced, the gym is very reasonably priced because the goal is truly to help people succeed, not just to make money. If you're looking for a motivating environment, great classes, and people who actually care about your progress, I highly recommend checking this place out. read more

I. Love. This. Gym! I'm a homeschooling mom of 3 and getting my day started at united fitness makes the biggest difference for my whole household. I have only had a gym pass once in high school, so basically I walked into this place not knowing what I'm doing at all. I've been going for 2 months now and I'm learning so many different exercises, slowly moving up in weight when I'm lifting and I'm feeling so much better already. The environment is super welcoming to anyone who is new. Coaches look out for you, give pointers and push you to be better. I looked around for a while for a gym to help me get back into shape and I'm so glad I landed here. OH and a huge bonus, your kids are welcome to sit in the lobby during your workout of for any reason you need to bring them with you. That's what I was specifically looking for and what a blessing it's been to find it! read more

I can't say enough wonderful things about United Fitness in Upland, especially Coach Josh! After driving by United Fitness for a long time my husband and I tried a free class and we were immediately sold. We signed up for a membership after our first class and I've completed two 6-week challenges since. I felt so stuck and discouraged postpartum, but Josh's dedication, expertise, and motivation have pushed me to achieve fitness goals I didn't think were possible. He provides personalized attention, nutritional guidance, and a supportive atmosphere that makes working out something my husband and I now look forward to. I love that all we have to do is show up - every workout is different and continues to challenge us. The gym is clean and all of the equipment is well-kept. Everyone has been so welcoming. United Fitness is a great choice if you feel stuck with your health and fitness goals. read more

United fitness has truly changed the game for me. If I could give 10 stars I would. Josh is a great trainer. He truly takes the time to get to know your weaknesses and strengths and pushes you through all your workouts. He's always making sure that your form is right and pushes you to finish strong. It's my first time ever trying a Bootcamp and let me tell you the first week was rough but once you get past that hump the way you feel is incredible. I look forward to getting up everyday to attend the 5am class now. I feel so much stronger and my endurance has drastically changed within a couple of weeks. In just a couple of weeks I've seen a change in my body too. I can definitely see myself doing this for a very long time. The workouts are never boring, everyday is different. I also love how clean everything is. 10/10 recommend. The best investment is yourself. read more
