After trying several bootcamps and CrossFit programs throughout Diamond Bar, Chino, and Chino Hills, I can confidently say this gym stands head and shoulders above the rest. My journey started with a simple Groupon offer, but the experience quickly exceeded my expectations—and I ended up signing up for a full year.

Mark, the owner, brings over 20 years of experience to the table. His passion for fitness and teaching proper technique truly sets him apart. He gives individualized attention and genuinely cares about helping you reach your full potential, no matter your starting point.

After just three months, I've seen noticeable progress in both strength and overall fitness. If you're looking for a program that combines expertise, motivation, and results, give this place a try—you won’t be disappointed.

I started going to next level gym last year. The community and accountability is great. Coming from a military background, I really appreciate the group workouts to keep me motivated. Coach Mark has helped me improve my form and physique. He is a constant encouragement to everyone. Whether you're 16 or 72, it's never too late to start taking your health serious. Highly recommend this gym.

Since we retired over three years ago, my wife and I have been going to Next Level Gym for personal training two times per week. We love the care, attention, and support that both Mark and Albert have given to us as they have taken the time at each session to customize, adapt, and personalize our workouts to fit our individualized training needs and to keep challenging us to get to the “next level” in our strength, flexibility, and endurance. They watch us closely to make sure we are doing the exercises correctly and safely, and they always have a workout plan ready for us to make sure we target upper body, lower body, core, and aerobic throughout the week.

Mark and Albert truly care about their clients and consider each one of us part of the Next Level family. We experience that at every session, and we observe the same personal dynamic when we arrive early to warm-up as Mark is finishing his time with the 6 a.m. boot camp group. As we watch him work with the boot camp group, we can also see that he provides the same personalized care, attention, and training to each of the members of the group, regardless of their age and ability level, as he does with us.

We unreservedly recommend the Next Level Gym for anyone seeking a supportive, friendly, structured, and challenging environment where they can be expertly and attentively guided to higher levels of physical fitness and health.

They never answered the phone. And even I left the voice message, sent the text, but no one ever answered to me. Also their website has a popped up ads that makes you can't click anything on their page.

Completely unprofessional. Albert completely ghosted me after I paid I full for one month. Do not waste your time at this gym.
