(Past retreat in 2019)



Are you ready to reboot your health and fitness?

Join us for an all-inclusive boutique fitness camp on beautiful Whidbey Island, Washington!

  • Be challenged and renewed by daily breathtaking hikes

  • Lose fat and build muscle in our fitness classes

  • Learn about healthy mindful eating, stress management and habit forming techniques

  • Relax and detoxify with massages and healthy organic cuisine

Our one week program is structured but personalized and our highly trained and compassionate staff will help you achieve your goals.

Our fitness guides will lead you on daily 2-4 hour hikes to nearby trails near the shore and in midst of forest and mountains. Groups are divided into at least two groups, from beginner hikes to more advance. Expect to sweat and get a good cardiovascular workout while receiving nature therapy. We will also lead you in a kayaking tour in beautiful Puget Sound waters. Morning yoga classes will stretch your muscles and prepare you for a continued week of activity. Evening classes consist of strength training, yoga, meditation and more aerobics. We are also thrilled to have personal trainer Adam Fawcett to work with us and he will lead high intensity interval training (HIIT) or functional exercise classes where you will strengthen your core and other muscle groups.


Local Whidbey island gourmet chefs will prepare individualized meals for your specific needs, using mostly organic locally sourced sustainably raised food. There will be no processed foods, caffeine, or alcohol. You will be on average 1400-1800 calories/day of meals and snacks throughout the day and you will not feel hungry. Instead you will be energized and feel fully sustained. After a week of eating clean, you will feel like a new person and lose weight. You will also learn about nutrition and mindful eating through lectures and discussions.

Learn how mindfulness promotes less inflammation in the body and reduces our fight and flight center.

You will be led in yoga and meditation and you will have quiet personal relaxation time at the lodge.


You will enjoy three 50 min massages during your week at the lodge by local therapists. Cleansing food and drinks will support your body to detoxify toxins and chemicals that build up from our environment. Sweating during your workouts and re-hydrating with clean water will naturally detoxify your body.

We have partnered with the vacation home The Quintessa on south Whidbey Island. It will be our base for accommodations, meals, exercise classes, and massage. Make yourself at home in 10 large comfortable suites (each with queen or king beds) and 5 bathrooms. Each room can accommodate a single guest or a couple. Maximum 2 couples/week and maximum of 10 guests per week.

Holly Peng MD

Family Physician and Integrative Health Coach


"I believe the foundation of "being the best version of you" and "living life to its fullest" is having HEALTH. And health is not the absence of disease but an optimal state of mental, physical and spiritual well being. I believe that everybody in this world can tap into that deserved authentic health and there is nothing more important.

Growing up with my grandmother (who lived until she was 105) I would hear her mantra in my ears -"watch over your health- without it, nothing else matters".  All the money in the world would be useless without your health. Without your health, you cannot be en effective parent, worker, or leader.

I believe furthermore that we were put on this earth to experience an exuberant life and the power to attain it is inside each one of us.

Here at Island Trek Fitness, we are dedicated to helping you achieve this exuberant life."
