Fitness & Weight Loss Packages in Koh Samui

Every package at Lamai Fitness Retreat is built around the same core idea — coached training, on-site accommodation, and structured nutrition — but with the length, intensity, and inclusions tailored to different goals. Whether you're here for a one-week kickstart or a multi-month transformation, there's a package designed to match where you are now and get you to where you want to be.

All-inclusive weight loss for any age and any starting point.

Founder Billy has coached on some of the world’s biggest fitness TV shows, and his student Nai dropped 64kg the smart way.
