Tessa Sandberg

Owner and Operator

I am an NSCA Certified Personal Trainer and started The Fit Xchange in Kailua Kona, Hawaii in 2013. Married to my high school sweetheart, Ben, and mother of two little girls, I am living the dream doing what I love in the most beautiful place on earth. I specialize in Circuit Training, HIIT (high intensity interval training), body building, yoga fusion, mat ab workouts, body weight barre and mat workouts, and macro counting services. I am a fitness blogger, novelist, nutrition guru, and lover of people, dogs, and sunshine. I am committed to pursuing an active, healthy, and content lifestyle, and educating others to do the same. Give me a call or text if you need a personal trainer, would like to join a group class, have any questions about fitness and nutrition, or just need a motivational kick in the ass.

Tammy Tolaas

I grew up in Southern Virginia then moved to Hawai’i in 2005.  From a young age my passion for movement was sparked through dance - from hiphop to ballet, jazz, modern, contemporary.  Dance has taken me around the world and the USA.   Throughout many moves and a high demanding physical career — like so many of us — my over all health took a back burner to my career and life.   I forgot about taking care of my body & health.  Through various wake up calls, sustaining and stewarding my body became increasingly important.  I tried acupuncture, regular massage, saw different types of physicians, but nothing has restored my body like Pilates!  I completed my Comprehensive Pilates Certification through BASI Pilates in California.  (I have since had a baby and can still testify that Pilates is an amazing way to restore the body!)  I love offering that same restoration to my clients.  When they finish a session with me and tell me, “I feel better, I feel taller”, I know I have given them a true Pilates session.

Don’t let your body become a forgotten body.

Alissa Malinowski

I am originally from Vancouver Canada but the beautiful Big Island and Kona has been my home for the past 11 years now. My husband and I have worked in the non-profit sector both locally and internationally, leading to many years of travel and rich various experiences. As a mother of three young kids, I have personally been so impacted by fitness in experiencing the benefits to not only to my body, but mind, emotions and soul. I am passionate about seeing people encounter how fitness can tie in with transformation across their whole life! When I’m not trying to get in a workout with a friend, I am drinking coffee, running around with kids, and am following up with the latest in the fashion industry. I am a certified personal trainer though Action International and am currently working through a specialization in Women’s Coaching. I love strength training, HIIT, functional fitness, and circuit style workouts. Contact me if you’re interested in pursuing personal training or setting up group training.

Jessica Norris

I am originally from the Northeast of the US but have been living in Kona since 2018 with my husband, who grew up here, and our two children. My passion for sports and fitness started with competitive sports which continued through college where I played soccer. Since then I found myself more and more wanting to find ways to help others with their health and fitness. I LOVE working one on one or in small groups and my desire is to help you to truly enjoy exercise, get strong and feel your best. I think finding enjoyment in fitness is what helps us prioritize and sustain it for the long haul, to not only reach a certain goal but to make it a lifestyle. I am ISSA certified in Personal Training and Nutrition and specialize in functional fitness, HIIT, and body weight exercises.
