This is my second time doing the challenge. I had great results the first time and more importantly was able to live my life and not regain the weight. After 4 months of maintaining, I was ready for the next level. I was skeptical I could meet my goal because was more interested in building muscle, which at my age can be challenging. I am pleased with the results. I lost 13 lbs and lost 5% body fat. I'm back into my high school size but stronger and more fit than ever. The classes are very effective if you work hard. The diet is easy to follow because of all the accountability and support. I recommend this program if you are serious about a change. For me, it was pivotal to see results week by week, as I am impatient. The more I saw it working, the more I was motivated to stick with it. Good luck!

The Best workout, coaches and meal plan I have done thus far. It totally changed the approach of diet.

I did the 6 week challenge and lost 20 lbs. The work outs are intense and the meals are simple.

Hi to the coaches at GTZ! I'm done with my 6 weeks challenge, I lost 22.2lbs thanks to all the coaches they are an amazing team and are always there to help. Shaz

I just finished my 6 week challenge and even though it was very tough I’m so glad I did it I lost 20 pounds and 4.6% body! All the trainers there are awesome and super encouraging. If you want to lose weight and willing to put the work in this place will be great for you.

Down 18 pounds with this program. Make sure you stick to the meal plan and the workouts as well because they are amazing.

This is the exact place that I was looking for. I have been to Retro, planet fitness, LA fitness before. But nothing was as effective as GTZ. Lost 18 lbs and 5.2% body fat in my 6 weeks challenge. Everyone at GTZ was so welcoming. No one at GTZ was judgemental. All the coaches - especially Jon, Mark and Frank - knows what they are doing. They are all so friendly, supportive and encouraging to archive my goal. Number of people in each class are limited so that all the coaches can give proper attention that is required for individual. Personally witnessed that if any individual who has any limitation to do certain exercises, then they will change up and customize the exercises just for that individual. Never seen such support and flexibilities from coaches at any other gym before. They offered variety of classes at multiple time frames. So that you will always have opportunity to join any class from there 3 facilities. They are not fancy like other gym out there but they know their basics very well and they proved it again and again (you will find all positive reviews for them).

Just completed the 6 week challenge, and lost a total of 23 lbs! Couldn't be happier with my results!

Hey this here is incredible. They help a lot of people including me, by guiding and motivation..you have the chance to change yourself completely!

GTZ is Wonderful! It is a great opportunity to grow and make positive changes in your life. I just joined with my son after we completed the six week challenge and we are really excited to continue our journey!

IT WORKS!!! I've followed the KETO DIET. I've never done a Ketogenic Diet before buthave a Jedi Mind to follow it correctly. Keto Diet has an additional feature to follow it strictly. If you deviate from the diet, the ketogenic effect will be lost, therefore... I was always keeping an eye to not loose it as I was seeing the effects EVERY WEEK. The training plans are very well documented, You could plan yourself ahead and have a clear view with videos about what to do and how to do it. So I followed those correctly and saw my body becoming what I wanted to be. AMAZING! If you have the commitment here are the right plans to assist you. I totally recommended it, it not only worked on me but also on a good friend that tried it before me. GO FOR IT 10/10

GTZ trainers were amazing, Kyle, Arbi, Frank, and Jessica were so motivating, helpful, and involved in helping me achieve my results! I am so glad I joined and can't wait to continue my journey eating healthy and working out!!
