Koh Samui Weight Loss Retreat with HIIT, Muay Thai and Personal Coaching

The programme is built around a personal consultation at the start of your stay. Your mentor goes through your diet, sleep, training history, injuries and mindset, then maps out a training schedule, nutrition plan and recovery plan specifically for you. Weekly check-ins follow so the plan can be adjusted as your body responds.

The training schedule runs from early morning through to late afternoon. Sessions include HIIT, strength training, yoga, Muay Thai and breathwork, plus runs along Lamai Beach. Because your mentor directs you to specific classes, you're not left guessing which session to join. Every class is coached, so intensity is scaled to where you are — challenging enough to progress without burning out by midweek.

Nutrition is taught rather than imposed. The café serves balanced meals made from fresh, whole ingredients, using Thai herbs, spices and vegetables. There are no meal replacement shakes and no eliminated food groups. Guests also get guidance on maintaining the habits after leaving the island, which is the part most retreats skip and the main reason people regain weight.

The team is led by founder Billy Orr, who coached on The Biggest Loser Asia. His client Nai lost 64kg and finished second on the show. Billy has assembled a coaching team that works with guests at their current level rather than an assumed one.

Accommodation is a private room on site, and the all-inclusive package covers meals and drinks, unlimited classes, spa sessions, massages, personal training sessions, ice baths, a detox flush, protein shakes, supplements, airport transfers, Garmin body stats tracking, and a water bottle and hiking bag. A VIP upgrade adds daily spa and massage, five PT sessions per week, a physio session, 3D body scanning, an IV drip, a Garmin watch on loan, and an aftercare programme for after you go home.

Stays are flexible — some guests come for two weeks, some for a month, and some return year after year. The retreat positions itself as a reset rather than a one-week fix: step out of your routine, learn new habits, and prove to yourself you can keep going.
