A truly great experience! Not like any other gym I have tried before. I did the 6 week program and lost all of the weight I had been struggling to lose for years. My personal trainer, Corey Sweeney, changed my life. I no longer hate working out and learning how to care for my body/health has affected every aspect of my life in a positive way. Koko actually cares! No gimmicks...No hidden small print... Just a staff that invests in it's clients and supports them every step of the way. I highly recommend them! It's the change and results you've been waiting for...

Koko 6-week challenge has been a life changing experience for me! I was completely successful with the help of my trainers, the nutrition program, accountability and the resources that Koko offers! I lost 20 pounds and almost 5% of my body fat in just six weeks. The number on the scale was one I never imagined seeing again. I am beyond thrilled! I’ve developed a new healthy lifestyle and outlook that goes far beyond the number on the scale! I actually look forward to my workouts! I am also much more aware of the nutritional aspect of my health. I know I need to make healthy food decisions, but now I know how to do that. Not only do I look great but inside I feel amazing! I have a new found confidence about myself! Not only am I physically stronger but I’m emotionally stronger as well. Thank you, Koko for supporting and encouraging me through this journey!!

What a fantastic place to work out. I finished the Koko Challenge losing 6.5% of my body fat. Woot woot! Enthusiastic trainers and encouraging participants of the challenge. Try it for yourself if you don’t believe me.

After seeing an ad on facebook 7 weeks ago and knowing I had to make a change (I was NOT buying any more clothes a size up again) I thought “why not?” I joined their free six week challenge that included a meal plan and exercising with their fine trainers for 45 mins 3x a week. After my last measurements today, the results are in. I am down 17.2 lbs, 10.2% body fat, and my BMI went from 28.8 to 25.8. I fit in a ton of clothes I didn’t fit into six weeks ago, I don’t feel weighted down and bloated. Ive got a bit to go, but I am so grateful for this place and for these people. If you are looking to lose the weight and just want someone to give you the roadmap and keep you accountable in the most loving way possible, this is your place. It clearly works. It’s not easy. But it works. The entire staff was so caring, they remembered my name every time I came in, when I was in a stall they naturally all gathered together to problem solve and come up with a solution (that actually got me out of it). Their equipment is great and I loved the variety in the workouts. I learned lifelong lessons that have changed my lifestyle for the better and I couldn’t be more grateful. They also have showers with soap and shampoo/conditioner, which is a bonus!

Koko FitClub is the perfect way to implement a lifestyle change in a positive environment where you’re held accountable. Goals become achievable with the help of the trainers and coaches! After completing the 6-week challenge, I feel like I've been set up for success implementing a healthy lifestyle. The nutritional information is easy to understand and works incredibly well! Don't be fooled though; you absolutely need to be dedicated to making the changes both in your diet and in your exercise methods. If you have the right positive mindset, you will succeed here! I'm also so glad that Cory and Jessica gave me the workout skills to continue after the 6 weeks. Thanks for the kick in the butt that I needed to get into a healthier place in my life 😊

I’m ACTUALLY holding back tears as I leave KoKo for the last time today. After seeing an ad on facebook 7 weeks ago and knowing I had to make a change (I was NOT buying any more clothes a size up again) I thought “why not?” I joined their free six week challenge that included a meal plan (no counting anything - just eat one food from each Column every meal), NO alcohol (if you know me, you know my relationship with craft beer), and exercising with their fine trainers for 45 mins 3x a week. The first week, I was sooo crabby (love you, Greg) and wanted to quit so many times but kept my motivation alive. After my last measurements today, the results are in. 
I am down 17.2 lbs
10.2% body fat
BMI has gone from 28.8 to 25.8. 
I fit in a ton of clothes I didn’t fit into six weeks ago, I don’t feel weighted down and bloated. Ive got a bit to go, but I am so grateful for this place and for these people. If you are looking to lose the weight and just want someone to give you the roadmap and keep you accountable in the most loving way possible, this is your place. I’m happy to answer any questions. It clearly works. It’s not easy. But it works.

If you're looking for a way to jump start your weight loss journey Koko is that path. The accountability you get with the trainers and other members is great. The workouts are hard but the result is weight loss. I really didn't know where to start and when I saw the challenge I thought now or never. Every week to see the results on the scale was amazing. My trainer Cory was right there cheering me on. I have never eaten so much for daily meals and that is what it took to eat the right foods at the right time to start the weight loss. I am so excited over what I was able to accomplish in 6 weeks with the support of KoKo.

If you want to get in shape in the shortest amount of time possible, Koko is perfect. The trainers are knowledgeable, professional, friendly and upbeat. The support and guidance they give is priceless. When my challenge is over, I intend to continue working out at Koko FotClub. They rock!

Best place if you’re looking for a efficient effective workout. The staff is super supportive and always upbeat and positive. Koko fit club of Grand Rapids is by far the best facility I’ve ever been to. It always feels like a personal experience even in a group setting. I feel proud and accomplished every time I leave. The results have been amazing

Best gymn environment ever. Thanks to the staff making it tough but fun. Seeing changes in your body is pure motivation!

So great even though I was skeptical. This is fitness for 'dummies', meaning you never need to think about what is next. It's all guided. Love it. Totally motivated by the numbers and I've seen a HUGE difference in only a week!

Koko FitClub is a great atmosphere for getting in shape, I don't feel intimidated by other people there, everyone is there to accomplish the same goal. Staff is really friendly and helpful. The best one is Lexie, she helps me stay focused on my fitness goals and keeps me accountable! I love this place!

I’ve been in a lot of gyms in my life, and I see more results in three months at Koko then I’ve seen in years at others. I plan on being around for a while.

This is individualized fitness at its very best! I have never felt my arms look more toned, belly fat is dissolving, and I really love going to the gym now! Koko FitClub is unique in its computerized machines that tailor create your fitness regimen - just for you. No getting lost with what you are doing with your weight training, and also ensuring you are getting the maximum results. Staff is extremely helpful and most friendly. Come by for a demo, you will be truly impressed!.

Tried on bikinis this weekend and I was not at all disgusted by what I saw, thank you KOKO :) Last summer I honestly told my husband I had come to terms with the fact that I would never wear a bikini again...and then I found you :) 22lbs down, and I am seeing muscles I haven't seen in awhile.

I've tried them all - Weight Watchers, Jenny Craig, Abs Diet, YMCA, Work Out World! Koko is the Best! Working full-time, and having 2 boys - I am definitely busy! Koko allows me to fit in a 30-45 min workout on my schedule - even 6am! And having Michael Wood in my ear for cardio, and the Smartrainer feedback on the strength machines is the perfect motivator for me! 27% strength gain in my 1st 10 weeks!! I am definitely a KokoNut:).

I love not having to figure how much to lift or how fast to go. Truly is fitness for those who need a trainer but don't want to pay for one. :)

I've been working out all my life, with personal trainers and on my own, but I feel like I'm more pressed for time than ever these days and I feel guilty if I spend too much time working out. I love that I can get a great workout in just 30 minutes and be done!
- Julie O

There is absoultely no way I would achieve what I do at this club ANYWHERE else. Due to work schedules, I'm typically here during unstaffed hours . Over the past few months I've been a member, I've lost over 15 lbs, my blood pressure is lower, and I am looking and feeling better than I have in 10 years! The exercises are challenging and workouts are never stale. Best of all, I am working out safely with perfect form. Thank you so much for bringing such intelligent training to our area! Looking forward to the next lanyard color!

Seniors can do it too! After 5 years of inactivity due to knees that needed to be replaced, I finally had 2 replacement surgeries & was ready to get back into shape. Fortunately, Koko FitClub was just down the street and in July of 2012 I started my road to fitness at the age of 68. It's been only 4 months and I have achieved my goal weight after losing 17 pounds. My strength has increased by 54%. My Q score started at 25 and is now 51.I was only able to do this because Koko is so much fun that I looked forward to going almost every day. There are no classes or schedules so I could just walk in anytime it was convenient for me. I feel better than I have for 15 years and I'm looking forward to continuing to improve my overall health. An additional perk is that I look better too.

Thanks to the manager, Roxie who gives me encouragement & creates a wonderfully positive environment. I'm so grateful to have Koko in Edmond, OK. I'm totally hooked.

My Koko story begins when I told my husband that I was finally ready to look for a personal trainer, after reaching a point of really getting sick of seeing my body in pictures! My son's wedding was in about 5 months, so time was of the essence. I am one of those people who join gyms, go faithfully for about a month, and then rarely go again. I never know if I am doing the machines correctly, etc. This is why I decided to look for a personal trainer. The next day, I noticed a Koko ad on Facebook. I had never clicked on a Facebook ad (and haven't since), but I was very intrigued! I clicked on the ad & signed up for a demo workout. I really liked it & have been hooked ever since! Long story short, I was very happy with the dress I was able to wear to my son's wedding and 4 of my sister's friends have joined Koko after seeing my transformation in the wedding pictures. I also encouraged my family members and other friends to join and they love it as much as I do.

More important than my dress size though is the fact that my cholesterol went down 51 points in 5 months. I have drastically cut down the amount of Diet Coke I drink, thanks to one of the best Fit Coach's around - Roxie! She encouraged me to try putting a green tea bag (they have the tea bags by the water cooler in the club) in my Koko water bottle and now I do it all the time. I honestly don't know where I'd be if I did not have Koko Fit Club in my life.

I love looking at my page on the website and seeing the total weight I've lifted and how many miles I've of cardio I have completed. It always amazes me - the non-exerciser - to see what I've accomplished! I turn 50 in a few months, in the best shape of my life! Thank you, thank you, Koko! Don't ever leave me!
- Laurie, Oklahoma City

I am so excited about Koko and regret that I didn't start this program when I first heard about it. I'd tried the typical gym scene, personal trainers, etc., and HATED it. Koko is a perfect fit for me, a 64-year-old who is diabetic and obese. I've lost many inches--I don't take measurements but I know how my clothes fit--and am enjoying a healthier lifestyle along with much more energy. The staff has been AWESOME! I intend for Koko to be a part of my life as long as it and I exist. Thanks Koko. You've done what no one else could do for me.
- Deb Magee, Edmund, OK

As a "woman of a certain age," I felt tired and weak when I decided to join Koko. The experience has been fantastic! It truly is like having a personal trainer. Sessions are short enough to keep from becoming discouraged, and the flash drive keeps me from cheating...as I used to do at a "regular gym." I'm stronger, more energetic, and feel good to know I'm improving my health and level of fitness. I love Koko!

I joined Koko FitClub just after signing up for Weight Watchers Online and chose the Diet Booster Workout Program. My goal was to lose 10 lbs. I was completely dedicated to working out 3 times a week and eating healthy. The best part, I am still able to enjoy my red wine! Within 2 months, I hit my goal weight and continued on with the Diet Booster program. Fast forward 8 months and I’m still losing weight while gaining strength and getting tone. I am down 27lbs and have my figure from 25 years ago, BACK!!! So, let’s talk dress size, I was a size 10, now I am a size 2. Honestly, I did now it was possible but here I am! My husband, Mychael has been on this journey with me and he is down 24lbs. Yep, that’s High School weight for him! We love Koko FitClub and feel like we have found the perfect workout for us to maintain a healthy lifestyle while feeling Fabulous!

I really, really LOVE KoKo. I joined the minute the Powell, Ohio location opened and I am so glad I did! I have been a gym member for many years but find Koko is the best fit for me. The equipment is great and the visual display is so helpful. Having the performance tracking in place to view is very helpful to me. I am a small business owner with over 130 employees to oversee, caring for mental health diagnosis individuals. As much as I love my clients, staff and job duties, it also creates a significant amount of work time, on-call duties and stress. I find Koko is my "me time" and a major stress reliever. I feel great when I leave and look forward to my next trip. The staff are really knowledgeable, helpful and I appreciate Koko allows me the flexibility of arriving before or after staffed hours due to my work and family schedule.

I am a 42 year old diabetic. When I started Koko FitClub in February of 2012, my diabetes was not doing so well and I was looking at going on insulin instead of medication. My A1C (3 month average of blood sugar) was 9.1 which is an average of 214. Blood sugars should range from 75-124 per my doctor.

When I started Koko my weight was 251 pounds and my cholesterol was 297. My waist was 38 inches and my clothes were tight. I was wearing extra-large shirts. It has been six months and I just did my blood work again. My A1C is now at 5.1, which is perfect. That is a 3 month average of 119. My weight is now 203 pounds!! 48 pound weight loss!!!! My cholesterol is now at 198, down into the good range. My waist is 34 inches and shrinking. Not only am I losing weight by staying with Koko, but my energy level is up. I only get tired at night and not during the day like I had been. I could have done some of this without Koko, but without the constant motivation of the Koko staff in Rapid City, SD and the constant encouragement from my family, there is no way I could have done it.

Thank you so much Koko for giving my life back and helping show me that with some simple changes and a positive attitude, it is possible to get back the things you love the most.

I have a hereditary condition called Lynch Syndrome (pretty rare, so no one knows what this is - you can google it :). As a result of this condition, I was diagnosed with colon cancer in 1992 at the age of 26. I'm also at a high risk for other cancers including endometrial and ovarian. To avoid getting those cancers, I had a preventative complete hysterectomy in November 2011.

I've never had a big issue with weight and because of that, haven't been compelled to work out consistently. However, over the winter, I started experiencing more rapid weight gain (about 10 pounds in a matter of months) and my body was very slow in recovering from the surgery. The final straw was in March 2012 when my husband, daughter and I visited my brother and his family in Colorado. They wanted to go on a fairly short, easy hike...I could barely make it!

One Saturday shortly after returning home, I received an ad in the mail for the newly opened Koko FitClub in our town. The indvidualized program, flexible hours, and short workout times instantly appealed to me. Thinking back to that hike the month before, I decided then and there to schedule a demo. I joined the club the very next day and have been regularly working out for over 4 months now. In the first 3 months I've experienced a 38% strength gain...amazing results for someone that couldn't even walk up stairs without getting winded.

My main goal upon joining Koko was to improve my physical condition for an upcoming trip to Colorado with my daughter's church youth group. I knew that there would be hiking involved and I did not want a repeat of the March hike! I am happy to say that I was able to hike and keep up with 18 high school kids for an entire week. I feel better than I've felt in a very long time! Thanks Koko!!
