“I had a wonderful stay and an amazing time at the Lamai Fitness Retreat, and I highly recommend it to everyone—it was an extraordinary experience. The atmosphere at the retreat is incredible, and I felt right at home from the very beginning, even though I went there alone. I was there for two and a half weeks and did the weight loss program. They’ve thought of everything—from the beautiful accommodations and three delicious, healthy meals a day to a personal trainer, great facilities, a super varied class schedule, and so much more. The personal training sessions with Lewis were the highlight; he pushed me to my limits, and I learned a lot about training and nutrition. Everyone else on the team was also very friendly, motivating, and always helpful. Now that some time has passed, I can say with pride and continued motivation that the stay has had a lasting impact on me. I’ve been able to transfer some of what I learned into my daily life and am once again giving exercise and nutrition a much higher priority.”

“What a week! It was my first fitness retreat and definitely one best week in my life. I arrived with nothing much expected and left seven days later filled with power, positivity, and new perspectives. Lamai Fitness crew were professionals in this business, from organization / admin to the trainings quality. My own personal favorites were hyrox and upper body strengths. I rarely trained my upper body and never tried Hyrox before. Thanks to the new trainer who recently joined Lamai fitness, I’m so glad now I can go home with these new tricks to include in my 2026 training routine. He was really good in making the challenging classes fun, motivational, and inclusive despite huge differences in fitness levels among the participants. Not easy to do but he managed to make it work! HIIT and Tabata are GREAT. Though these two were my routines, the one-hour session brought it to another level! Never thought my body could do it but it did, repeatedly. Loved it! Box Fit. It gaves a flavor of Muay Thai. The instructors were super friendly and inclusive. I felt very uncomfortable when I first joined the class as I didn’t even know how to kick (!). The instructors taught me and showed me how to do the moves. I had fun :D although I had to admit that boxing wasn’t my thing. Oh well you never know until you try! Go check it out! I loved the meal plan. They all tasted very good especially given how healthy they are. I’d totally recommend it! Missing the chicken wrap already. I stayed at Crystal Lamai, an accommodation partner of Lamai Fitness. The room was clean and basic. Super close to Lamai Fitness and other amenities in the area which in my opinion is the most important. Stay close so you don’t have any excuse of missing a class or training.”
“I honestly can’t praise Lamai Fitness Retreat enough. From the moment I arrived, everything exceeded my expectations. The accommodation was so convenient - so close to the facilities and really well equipped making it easy to settle in and focus on my training. The class schedule was excellent. Such a good variety that there was always something to get involved in. Whether you wanted to push hard or mix things up, there was never a dull moment. The coaches and staff truly made the experience though - they are amazing. So friendly, welcoming, and genuinely invested in everyone there. I left feeling like I’d made real friendships, not just attended a retreat. I arrived going through a bit of a tough time, and they went above and beyond to support me. They checked in with me, listened when I needed to talk, and created such a positive and encouraging environment. At the same time, they pushed me hard in sessions and helped me realise what I’m actually capable of, which was incredibly empowering. I originally planned to stay for just one week… but ended up staying three. Even then, I didn’t want to leave, which says everything! The onsite cafe, Eats, was another highlight - delicious food, high quality, and fresh produce at every meal. It made such a difference to the overall experience. It was also nice to mingle with other people and have a chat between classes. I arrived feeling a little lost in life, but I left with my confidence fully restored. I’ve come home feeling motivated, focused, and hungry to push myself even further than I ever thought possible. I will without a doubt be back ❤️”
“I visited Lamai after a recommendation from a friend for two weeks in late Feb 26. I can’t rate it highly enough for the quality of the training, programme that allows you to really push yourself and recover (including sound healing, breathwork and daily stretching) as well as time for yourself to explore or just nap (can recommend!) I stayed at the apartments so spa access was included daily which was a blessing, beautiful pool and recovery facilities like ice bath. But honestly the best thing is the people and friendly, supportive environment. I met people from all over the world who arresting to make a change or invest in themselves and it made for such a great experience as a single woman.”
