Koh Samui Weight Loss & Fitness Retreat: Jungle Training with Myzone Tracking

Koh Fit sits in Lamai, on the south-east coast of Koh Samui. The camp is deliberately set back into the jungle, away from the main strip, so the days stay quiet and the focus stays on training. The beach is a few minutes away on foot, and the nearest bars and restaurants of Lamai are close enough for an evening walk on a rest day.

The training floor is 500 sqm of functional space, with a separate air-conditioned cardio room and a multi-storey gym kitted out with weight machines. There are two swimming pools, a yoga room, an on-site health food café and an onsen spa with massage services. The gym is open to retreat guests throughout their stay, and most programmes include unlimited access.

Classes run throughout the day. Depending on which programme you book, you might do 20 to 30+ classes a week, with 2 to 5 personal training sessions, daily yoga, and between 1 and 7 Muay Thai sessions. Weight-loss guests get structured weight-loss classes, two PT sessions a week, a nutritional consultation and a 7-day detox programme; the VIP Transformation package stacks on weekly assessments with body-composition analysis and up to 10 Muay Thai sessions a week.

What separates Koh Fit from a generic bootcamp is the tracking. Every guest wears a Myzone heart-rate belt, and the trainers use that live data to set intensity zones in class and to show you what you've actually done each day. Weekly assessments mean the programme gets adjusted rather than just repeated.

Recovery is built into the schedule rather than treated as an add-on. Massages and spa sessions are included across the programmes — one to three massages a week depending on the package — with an onsen spa on site. Yoga runs daily, and there are guided hikes around Koh Samui for the packages that include them.
