21 Day Muay Thai, Yoga & Culture Wellness Retreat, Thailand

JP Boxing Gym runs this 21-day program in Phitsanulok around a genuinely demanding daily split: Muay Thai and boxing training each morning, CrossFit or sparring most afternoons, and yoga — Hatha, Ashtanga, and Yin — worked in as active recovery rather than the main event. The location sets it apart from the beach-town Muay Thai camps that dominate the category; training happens inland, with Saturday mornings given over to alms-giving at Wat Phra Si Rattana Mahathat — known locally as Wat Yai — a roughly 700-year-old temple that houses one of Thailand’s most revered Buddha images.

The 21-day length is long enough to build real conditioning rather than sample a few classes: mornings often start with optional sunrise runs or temple visits at 5:30am, training runs through the morning, and the afternoon mixes strength work with sparring before evening recovery. Thai massage, sauna, and ice baths are built into the daily schedule rather than offered as extras, and a free protein smoothie follows morning training. A separate Pagoda Mountain Challenge and training sessions at a site billed as the King Palace add variety to the straight gym-and-mat routine.

Watch out: Lunch isn’t part of the included program — the schedule runs training and recovery through the midday hours with breakfast and a protein smoothie in the morning and dinner in the evening, so anyone used to three set meals a day should budget for a midday option nearby.

Accommodation is a private, air-conditioned room with en-suite bathroom for the full 20 nights, with airport pickup and drop-off included. Beyond training, the cultural side runs deeper than a single excursion: night and morning market tours, a Wai Kru ceremony, and sessions at historic sites sit alongside the temple visit. Dietary needs are covered for vegetarian, vegan, and raw food diets, and free Wi-Fi and access to a local swimming pool round out the amenities. A near-500-review base backs up the 4.96 rating, a reasonably large sample for a program this long.

Insider Tip: Cancellation is free up to one day before the start date — unusually flexible for a three-week commitment — but flights, travel insurance, and visa fees are excluded and need budgeting separately. Thailand’s cool season (November-February) suits the outdoor training load best.
