Kelvin is a wonderful personal trainer. I’ve been working out with him right over two months and I’m extremely happy with the results. I’ve hired several personal trainers in the past. No one works like him. He’s definitely the best. I love that you’re in and out in 30 minutes and you see results that must be why they call him Mr. results 10 out of 10 recommend

After relocating to Spartanburg from Atlanta seven months back, finding a personal trainer became my top priority. Fortunately, I struck gold when I found One on One Fitness and set up a session with the owner, Kelvin. He stands out as one of the finest trainers I've ever had the pleasure of working with. Kelvin's upbeat attitude fosters an excellent atmosphere in his gym. His encouragement and guidance have significantly impacted my strength and fitness levels. I look forward to every personal training session and am excited about the open concept gym next door, “The One”, launching soon! Can’t wait to join more group classes!

I was putting in time at the gym, but wasn’t getting the results I desired. I started doing one on one sessions with Kelvin twice a week and joined in a couple of his Strive classes every week too and started seeing amazing results. I wanted to keep going further and decided it was time to compete. Kelvin coached me through the entire process with specific workouts and nutrition. I won 3 first place trophies and my professional body building card.

His 3D scans, meal plans, and one on one sessions got me into the best shape of my life. Kelvin is amazing at designing workouts to help you build your best physique and reach your goals.

The owner Kelvin N...Mr Resultz, is amazing!!! Hes not my trainer but his business is 💯!!! He trains too. 💪🏽💪🏽The business helps understand and recommends meal plans to meet goals, the environment is always clean, there is state of the art equipment and always keeping it updated. It's a family friendly training facility and very personal. Its not a gym like Planet Fitness or Anytime. Its BETTER! They know you by name.. if you want or need personal attention to reach your goals. This is it!!! I OBVIOUSLY LOVE this place!!!! Stop in and check it out!!!

Tony Wilson - Trainer

Best trainer in the area!!!!! I've had a few. He gets to know his clients and the best approach to train and motivate them. Trains the whole body not focused on certain areas! Doesn't do more than he assesses you can handle. Holds you accountable! If you want to invest in someone to train you, he's the one. He loves his job and if you put in 💯 he's going 50% more so you can reach your goals. You won't be able to tell him HOW to train you. That's his job. That's what you're paying him for.....💪🏽💪🏽💪🏽 I highly recommend him!!!

The fact that your trainer gets satisfaction at seeing you sweat and say you can't get better if you don't keep going and try something different! Kelvin Nesbit is the greatest cheerleader and hype man that can truly make sure that his guidance is going to let you see results! Now if you can move the next day is not guaranteed but you will never be disappointed about the quality of service that you get.

One on One is the most amazing gym you will ever set foot in. I have been there for 3 years and not only has it helped me completely transform my body and health, I have made lifelong friends that I am so grateful for! Kelvin is a dedicated owner, friend and trainer. He will work you hard and I guarantee you will meet your goals. Our 5am bootcamp is my lifeline! We work hard, we laugh, we sweat and complain- it’s our own little family at the crack of dawn ❤️ Holly is such an amazing leader- she is dedicated to each of her clients and her bootcampers. She will do absolutely anything she can to help you meet your goals! And then there’s Styles. He recently started working with my 6 year old daughter to help her train for competitive gymnastics in the future- he is WONDERFUL with her. She is very timid- but he always gets on her level and makes her 100% comfortable and she has a great time every session. I love and am so thankful for all my family at one on one!

Kelvin does a great job of listening and understanding your goals and needs and combines his knowledge and experience to help you reach your goals; and many times surpassing them. The boot camps each day are filled with great energy and encouragement and something new each day to keep your interest. His meals plans and meal prep are affordable, tasteful, and filling. There’s a no judgment zone as the environment is for all shapes, sizes, and experiences in working out. If you want results that are long lasting and life changing, One On One Fitness is the place to go!

This is absolutely the best gym in Spartanburg! I have been taking the boot camp class for nearly nine years and I never get tired of it. Every class is different and you will be pushed to your limits but you will meet goals and milestones you never thought were possible. I recently started the MMA training sessions and I LOVE them! All of the trainers actually care about your personal fitness journey and celebrate your successes with you. There is no judgment as everyone there is working together and encouraging you to be your best. I could never imagine working out anywhere else!!

My mom and I have been going to Kelvin since he first opened!! Fair warning: his workouts never get easier. He knows how to keep you motivated and is always switching things up. And the bootcamp/spin classes have such an encouraging and motivating atmosphere. BEST gym in SC, I wouldn’t train anywhere else!

I always thought I hated working out. Turns out, I just hadn’t found the right kind of work out. I found it at One on One Fitness. I didn’t think I would ever enjoy going to a gym or taking a class. I was wrong! During the 6pm bootcamp, Kelvin keeps you moving the entire time and you are never bored or watching the clock for the workout to finally be over (what I usually did during previous workouts). You never know what to expect and it is exciting and challenging every time.
If you’re looking for a more personalized experience, there are multiple professional personal trainers with whom you can work. In my personal training sessions, Kelvin pushes me to go further and work harder than I think I am capable of. The trainers will also work with you to design a nutritional guide or you can order food from an amazing meal plan service.
One on One has something for everyone at every level. You have nothing to lose but some extra lbs!

My very 1st training session was with owner (Kelvin) about 10 year's ago and his training style and personality won me over. I'm now back to Training with him again and at One On One Fitness for almost a year and a half. He got me to keep showing up last year despite my health trying to take me down, I kept pushing and now feeling great! He's awesome to work with but it's no walk in the park up there!! He's tough but efficient, and but trust me that's what you need! He trains small teenagers to elite athletes...to middle aged women like myself. I highly recommend! ⭐⭐⭐⭐⭐

Everyone, including all the trainers and boot camp attendees, at One on One Fitness are so nice and friendly. Kelvin is seriously the best trainer I’ve ever had, he pushes me and encourages me when I want to quit and give up. He’s not just my trainer, he’s become a friend during my fitness journey.

Been going to One on One for more than 8 years. Kelvin can customize any workout to your needs and goals. He has personally trained me to complete Assault on Mt Mitchell (103 mile bike ride finishing on top of Mt Mitchell, NC at 6,683ft) and rehabilitate my shoulder from rotator cuff surgery (I played in and won a tennis tournament 6 weeks after surgery).
I cannot say enough good things about One on One. Just be ready to train hard and you will see the results from Mr Resultz
