Fitness & Weight Loss Camp in Koh Samui with Myzone Tracking and Muay Thai

Koh Fit Thailand is based in Lamai, on the southeast coast of Koh Samui. The site sits back in the jungle, a few minutes' walk from the beach, and the whole campus is built for people who are there to train rather than to holiday. The main gym is a 500 sqm functional fitness area, with an air-conditioned cardio room, a multi-storey section of weight machines, two swimming pools, a dedicated yoga room, an on-site health food café, and an onsen spa and massage service. Opening hours run 06:30–21:00 Monday to Friday and 06:30–20:00 on weekends, which tells you what the schedule looks like: early starts, full days, evening wind-down.

Every programme is all-inclusive — accommodation and food come as standard, and the training content is what changes. The Weight Loss Retreat packs in structured weight-loss classes, two personal training sessions a week, daily yoga, one massage and two spa sessions a week, plus a 7-day detox programme and a nutritional consultation. The VIP Transformation is the most intensive: 30+ classes a week, five PT sessions a week, daily yoga, ten Muay Thai sessions a week, three massages a week, four spa sessions a week and weekly assessments with analysis. The Muay Thai Retreat is two Muay Thai sessions a day, five S&C classes a week, one PT session a week, three spa sessions a week, hiking on Koh Samui, and nutrition designed for fighters. The Total Fitness Retreat sits between them: 20+ classes a week, seven Muay Thai sessions, an onsen spa session, Koh Samui hikes, and full gym and pool access.

Coaching is group-first, with one-to-one time built into each programme — two PT sessions a week on the weight loss track, five on the VIP track. Myzone™ heart-rate tech is used across the retreat so heart rate and calorie burn are tracked and reviewed rather than guessed at. The gym itself is the reason most people pick this place over a hotel fitness room: proper functional kit, a real cardio floor, machine weights across multiple storeys, and a separate yoga room so classes aren't held on the gym floor.

Rooms are set back in the jungle, away from the main road, and are designed to keep you focused on the programme — you're on site for training, meals and recovery, with the beach a few minutes away when you want it. The café on site handles the food side, which matters on a weight-loss or fighter's programme where portions and macros are being managed for you.

There's a running early-bird discount: book any 3+ week all-inclusive retreat at least three months in advance and get an extra 10% off the total package. It doesn't apply in December and January. The team can be reached by WhatsApp on +66 (0) 80 472 2356.
