Can you imagine training in a paradise jungle with the very best coaches in the world, top-of-the-range equipment and one of the newest, most beautiful gyms ever built? That is Zamaya, and it is where Ultimate Fitness is taking a small group twice a year.

We have been running fitness training holidays since 2008. It is what we do, and we have seen a lot of places. I have been to Zamaya, and I can tell you honestly: there is nowhere better in the world than this. It is an absolute paradise, and it is a monster of a training centre, with everything you could ask for. It was imagined by people who wanted the absolute best for fitness training holidays, and they built exactly that. Every detail has had attention, from the bamboo pavilions to the luxurious villas.

The scale is hard to believe until you are standing in it. Room for over 200 guests, with 48 private villas and growing, all inside one training campus carved out of the Mayan jungle outside Tulum. At its heart is a vast covered, fully matted gym under a soaring bamboo roof. Beside it is an indoor hall built for Brazilian jiu-jitsu and the combat arts, and a glass-walled Pilates studio that looks out over the whole resort. A running track winds between the pavilions, the pools and the villas. Recovery is a department of its own: sauna, jacuzzi, ice baths, a sensory deprivation chamber and eight massage rooms. The restaurant is built around performance nutrition.

You go there to be there. To exist, to train, to relax, eat, sleep, train and repeat, in its purest form. Coached sessions every day across CrossFit, HYROX, HIIT, Muay Thai, boxing, Brazilian jiu-jitsu, Olympic lifting, Pilates and yoga, at whatever level you are. Then a swim, a massage, a long lunch, and the jungle quiet in the evening. When you want the outside world, the white sand and turquoise water of Tulum's beaches, the cenotes and the Mayan ruins are a short drive away.

How the Ultimate Fitness week works: we take a small group, twelve places per departure, filling three or four villas, and everything is included in one price. You choose how you want to live: a room in the hotel, a suite, or a bedroom in a private villa with its own pool shared with your training partners. Everything below the line is the same for everyone: the coaching, the food, the recovery and the group.

It is definitely not the cheapest week you will ever book. But cheapest is not best, and this is the best. Places on Ultimate Fitness departures are deliberately limited. Secure yours with a US$1,200 deposit today and save 10%, or spread it out with our payment plan: US$600 now, US$600 six months before you go, and the balance 12 weeks before you fly.
