I found D1 while I was prepping for my fire academy and could no be more impressed with the level of workouts provided. Marcus and the other coaches are enthusiastic, knowledgeable, and passionate about health. For anyone looking to change up their workout routine I would highly recommend D1. Give it 30 days and you will hands down feel better, look better, and be performing better.

If you’re looking to get stronger physically and mentally this is the place to be! Whether it’s morning, night, in season, off season there’s no excuses. I’ve been coming here for some good time now and I’ve noticed major differences. I have became more explosive, I’ve gained a great amount of noticeable muscle and I’ve grown very strong mentally. Marcus is the man to see. He will work you till you don’t want to anymore, which will only make you stronger. Stop sitting around and go make a difference!

A Life-Changing Experience for My Boys! My two sons (ages 8 and 7) have been attending D1 Training Milton in Alpharetta, and I can honestly say it has been life-changing for our family. What makes this gym so special is how they turn exercise into fun. Instead of just “working out,” the coaches use games, challenges, and physical play that keep the kids excited and motivated. My boys look forward to every session—they don’t even realize how much they’re working out because they’re having such a great time! As a mom, this program has been a blessing. After my husband passed away a few years ago, it’s been hard for me to keep up with the more physical play my boys love. My oldest son also developed tics around that time (eye movements, arm popping, mouth opening), and after consulting with a pediatric neurologist, I was advised to find a sports program where he could stay active in a fun way. Since joining D1 a year ago, his progress has been incredible—his tics have completely gone away, his mood has improved, and he’s happier, more confident, and more active than ever. My younger son joined earlier this year (2025), and he has loved it from day one. He’s built strength, energy, and a love for sports that I know will stay with him. We are so thankful for Mr. Marcus and all Coaches for their amazing environment they create for kids. D1 Milton has truly given my boys not only physical fitness, but also joy, confidence, and an outlet that has improved their overall well-being. I highly recommend this gym to any parent looking for a fun, supportive, and effective place for their kids to thrive!

I love this gym! Marcus and Laura are amazing coaches who have helped me discover a real love for heavy weightlifting. They’ve encouraged me to push past what I thought were my limits. The morning class is incredible, and the supportive atmosphere makes all the difference. Highly recommend to anyone looking to build strength and mobility!

My kid and I have been taking the guided gym classes at D1 for a few months now, and it’s been a really positive experience. The coaches do a great job of encouraging and pushing you just enough to improve, without ever being too intense or overwhelming. The workouts are structured, effective, and easy to follow no matter your fitness level. What I also appreciate is the friendly atmosphere—everyone we’ve met there has been supportive and respectful. My child is part of the youth/teen program and has been enjoying it a lot. It’s been a great way for him to build strength, coordination, and confidence.

I highly recommend D1 Training. I have been going consistently for over a month and I can already see results. I like the structured, consistent, challenging and encouraging environment, which helps me be accountable. Don’t be intimidated about weigh lifting, if you are not familiar with the techniques, you will quickly learn and feel comfortable.

Highly, highly recommend!! I am 46 years old have been working out at D1 for 5 months. I started with 1:1 sessions with Marcus and have now moved into the 6 am class. The workouts are challenging and I feel great!! I have lost 40 pounds in 5 months with a dedicated routine and dietary guidance from Laura.

D1 Training Milton is a GREAT option to supplement a kiddo's competitive sports training. They do a great job with age appropriate training and make it fun for the kids. Tech platform to sign up for training is easy. This training option is a good value too.
