    As soon as i started working with Garrett my whole mindset changed on staying motivated / dedicated! i love how he treats you as if you were his main focus! it’s a great feeling to know he’ll check up on you and/or work through ANY question or issue you have! You work as a Team together and he’s not just a coach telling you to do this or that because he says so. i look forward to his replies back on check in days and trust him with my goals. (there’s not many i can say i trust with my fitness / nutrition) He’s super quick in responding too! Any question you have is answered, and he never just has you do something without telling you WHY. He makes sure you’re on the same page, understanding the game plan and why he has you doing something. He really listens to you with what is going on with your body, life, or anything that plays a role in your nutrition / fitness. He factors those types of things into your plan, which makes him even better. I’ve had other nutrition help, and i never felt like i was a priority, more like a number, so the fact that Garrett is by your side along for the ride with you makes you WANT to stick to reaching your goals even more. Nothing but positives from me! He’s awesome!! Never have i had such awesome and CONSISTENT changes like i have.

    After several overly stressful years in my previous career, I found I had "somehow" gained a whole lot of weight! I knew I needed a big change, and I knew I had zero interest in all those "diets" out there. I felt like most coaches just wanted to sell me something. 😉 I was referred to Garrett by friends at Orange Theory in Fishers, IN. And "WHOAAA" as Garrett would say when he's excited for me, I was immediately in love with his knowledge, experience, the plan he built for me and his never-ending fun and positivity! I do not believe I would not have been successful without Garrett coaching me and holding me accountable. He totally works with you as a partner, meets you where you are, and coaches you as if you are his only client. I took a bit slower approach than others might because it worked well for me. End result? 24 weeks, 24 pounds gone, lots and lots of inches gone, 3 dress sizes down. The best part? What I've learned from my time with Garrett is not "how to go on a diet and lost weight." It's better than that. I've learned how to eat right every day, for a lifetime!

    positive review  I have been working with Coach Jason for a month now and I am beyond happy with my progress thus far!! I still have 12 weeks left of my program and I can’t wait to see the changes at the end of this! Tandem Nutrition takes the hard work out of eating healthy by providing you all the tools you need to be successful, you just have to be willing to make the changes to see results! Positive, encouraging, and super knowledgeable are just a few of the words I’d use to describe Jason and the Tandem team!

    positive review  hey everyone! Garrett is the best health coach I've ever encountered. he actually cares about you and your goals. he's not just someone that throws facts at you that you don't understand then doesn't help you at all. He helps and a lot. I've lost so much weight under his guidance and on top of that I've gained A LOT of muscle so most of weight loss is pure fat! I was dieting long before I met him I did lose 12 lbs however I was not happy! Dieting sucks. now I don't feel like I'm dieting but rather feel GREAT and losing body fat is a plus while feeling good! 10000000000000% recommended!!

    positive review  What a great experience being coach by Coach Garrett! From now on I know who to go to for any fitness needs and the only person I would recommend. I knew something was going to be special about my time with Tandem Nutrition. At the beginning with a phone interview to truly understand my why for dieting and get to know me so a personalized planned could be created specifically for me and consistently providing support. I’ve had multiple coaches in the past but nothing like Coach Garrett. If you are looking to change, lost or just need guidance, look no further then the team at Tandem! With Garrett you aren’t just a client, you are more like family. Also Coach Garrett is by far the ultimate pancake connoisseur I’ve ever met and you are always invited to chow down some pancakes with him and the family at Tandem Nutrition!

    Garrett understands food ingredients in a way that most do not. He translates this to common sense small changes in daily food choices that are easy to adopt. As a client of his for over a year, I highly recommend his services.

  • positive review  The Tandem Nutrition team absolutely knows what they're talking about! They're full of useful information, and I love that they preach eating the foods you love while becoming healthier. I don't at all understand Coach g's obsession with pancakes ?, but I guess I can let that slide ? #teamwaffles ? If you're looking for coaches who are willing to work with you, who are kind and supportive, but who are also willing to tell you the truth when you need to hear it, these are the folks for you.

    negative review  I started my journey 3 months ago with Tandem Nutrition (working with coach Kasey). In these past 3 months I have learned so much about myself, let alone how to lose fat. I honestly didn’t think I could lose fat and weight on my own. I started this journey at 183 lbs and today I weight in at 168.4. I’m extremely proud of myself for the goals I have accomplished during this time. I am extremely grateful for Tandem Nutrition. Coach Kasey is an amazing person and taught me a lot. Thank you!

Being a highly experienced Health and Fitness coach myself, I can say that his knowledge and commitment to personal relationships is the BEST I've ever experienced in ANY business. Working with Garrett one-on-one has saved me both TIME and MONEY. Not only am I in the best shape of my life, but I am stronger mentally and emotionally all because of Garrett's guidance. If you're looking for a solution to be the best version of yourself...this is it!

    positive review  What if I told you, there is a trainer who is breaking the mold of diet and training? What if I told you, you could eat the foods you love and still have a plan to lose fat and keep it off? Then, Tandem Nutrition and Coach g (Garrett Serd) are the answer to your struggles. Don’t be like me, don’t waste your time stalking this man on various social media to see what he’s saying and what others are saying about him (I followed him on IG and FB for nearly two years). Without a doubt I’d recommend coach g to anyone looking for nutrition and training guidance. But you get so much more than just that, he’s a great motivator, he’s always positive, he’s a spiritual and religious guide as well (for those who want it, he’s never pushing anything on anyone), think of coach g as a life coach. It’s a total package, body, soul and mind!! Coach g truly does care about his clients, he’s checked on me more than I have, he has always kept the lines of communication open. I have dealt with other online coaches in the past who barely cared if I even checked in and were too busy with other things. Coach g brings his focus, positivity and dedication to each client. His portfolio of clients is the real testament to his success. His training and nutrition plan approach is amazing and hits all your needs, but I’d recommend you come with questions and that’s where you will see why he’s the best. He will listen to you concerns, he will make changes where and when needed, best of all you will notice how humble he is in his method. He will never push an agenda, he wants you to be happy and have the tools to be successful in attaining your goals. Coach g is truly in tandem with your success and goals. Its not a one size fits all approach at all, yeah there might be similarities in the approach but each one of his clients has their own customized training and nutrition plan, which I love. He will make himself available when you need him, he offers so much of his time and knowledge in pursuit of dispelling the many myths around training and nutrition. Just follow him on IG or FB, it’s a free education on those topics, imagine what you’d get if you hired him as your coach.

    positive review  I was introduced to Garrett and Tandem Nutrition through a friend that had great results. Working with Garrett, or Coach g, was the best decision of my life! I had previously struggled to stay consistent with my diet as I fell victim to many so called "fad diets." Coach g helped me realize that I could still enjoy food and be healthy at the same time! I saw great results and lost, and kept off, around 20 pounds during our time together. He truly cares about each one of his clients and Tandem has a great team of dedicated and compassionate individuals. If you are ready to make sustainable life changes look no further than Tandem!

    positive review  I've been involved in some sort of fitness most of my life. As I got into my 40s I slacked off. Believe me that is not the age to do it! In the past 2 years I've really applied myself to training for a better physique. With all of the hours in the gym mounting up, I still wasn't seeing the result that I wanted. Garrett taught me that I can't out-train a bad diet. Many of the principles he teaches I "sort of knew." But it has been the fine points that have helped me the most. I eat foods I love because Garrett based my plan around those foods, and I feel great. I'm still not at my goal, but I know with Garretts help I will be!! One of the best decisions for my health I've ever made!

    Garrett has been such an asset to my life as a friend, coach, and client! He is one of the friendliest guys around that has given 100% of his efforts to his education and clients. He also got me to the leanest I have ever been on the bodybuilding stage and I cannot thank him enough:) He is professional, empathetic, and truly cares about his client's success. He is constantly giving value each and every day. If you are thinking about working with him, at least follow his business. He posts informational posts every single day. Once you see the value that he adds, it will be a no-brainer! He will be the only choice.

  • positive review  I have been working with Garrett since July, following a bikini competition. I was in a really bad place physically and mentally, rebounding badly after my show. When I first started working with Garret, we focused on hitting a specific calorie goal instead of macros. This helped me so much mentally. Garrett took the time to sit down with me and discuss my goals and plans in the NPC. He was 100% supportive and attentive to my goals while also being honest about my need to take a year off from the stage. He is one of the most knowledgeable people I know in this field, and always takes the time to answer my questions and explain his reasoning behind protocols. Garret puts the health of his clients first and truly wants them to succeed. I would recommend Garret to anyone looking to lose weight, get fit, or prep for a competition!

He responds very quickly to any question that I may have and also provides materials for me to read to support his recommendations. I am well on my way in achieving my goal. I am thankful for Garrett and the program that he has set. I would highly recommend Garrett to anyone! Thank you Garrett!

    Garrett has been so helpful. Mentally I know how to eat to be healthy, but having G walk with me has been wonderful. He has listened to my thoughts on calories with my age and physical abilities and adjusted where it was needed. The way he coaches and his encouragement speaks to me and motivates me to want to be better each day! He is a true blessing in many ways.

    I've tried everything....starving myself, going to the gym daily, low carb, low fat, high protein, etc., etc., etc. I would get so frustrated after trying these "fads" that I would become demotivated within 2 weeks and give up. I got to a point where my clothes didn't fit, I was tired and didn't feel healthy. Finally, I was introduced to Tandem Nutrition and this has been life changing. Garrett taught me the basic concepts of Macros and what good nutrition looks like. He has debunked myths that I have followed for years that were never successful. Finally, I have a nutrition plan that I can follow with normal, everyday food and am now much more knowledgable of what a good diet looks like. Garrett holds you accountable but also recognizes that life can get in the way and is your biggest cheerleader. He is reachable 24/7, always pleasant and supportive. Thank you Garrett for your expertise and support...you have been a blessing to me.

  • positive review  If you’re like I was and know you need a change but are overwhelmed with all the “fitness” advice, Tandem Nutrition is the place for you. Not only did I lose a substantial amount of weight (30 lbs), but I also learned how to eat so I can keep the weight off. That’s the part that was missing from my previous attempts to lose weight. Tandem showed me it wasn’t just a diet, but a way of life. Coach Barnes and Coach g provide advice, accountability, and most importantly a way to get you to the life you want to live. I highly recommend Tandem Nutrition. You won’t regret signing up.

    Working with Garrett has been a rewarding experience and a great investment for my health. Learning more about nutrition and having someone hold me accountable was something I needed to help get me in the right direction. He always answered my questions and was very prompt at getting back to me. I have a very busy life that I enjoy, which makes nutrition go out the window at times. Working with Garrett I learned how to look at some foods differently and find alteratives to what I was already doing. It was a great learning experience and I would recommend him to anyone looking to take the next step on their fitness/health journey. Great job Garrett!!

    positive review  So many great things to say about the Tandem Team! I had the privilege of working with Jason Barnes as my coach and he was the most helpful, positive, and motivating Coach I could have had. Garrett and Jason often offered words of encouragement and were always there to answer any questions I had. I started my journey with Tandem wanting to be a physique competitor, and over the course of my 11 week prep, the knowledge and information they shared with me was always science-backed, so I had a sense of comfort knowing I was doing the best I could for my body while on a prep. I loved having the support from not only Garrett and Jason, but the whole Tandem community, as multiple people would reach out to me regarding my progress! Another one of my favorite things Tandem Nutrition offers is community events, so you can tell they are invested in making the community a healthier, happier place. I love what you guys are doing, and keep up the great work!
