About Us

Welcome to Bali’s 1st CrossFit gym!! S2S stands for Strength to Strength. We endeavor to take you on a journey from one success to a higher level of success – from Strength to Strength.

Established in January 2013, we have a mission to introduce an effective training program in a judgment free, fun, and welcoming environment. A place where you can feel like you belong no matter where you’re from. We want to hear your story, get to know you, help you reach your goals.

We run our WODs (workout of the day) in multiple places – our gym, soccer field, or the beach which is only a few minutes away from our gym. Every session we run is well thought out because your well-being is our number one priority.

Meet Justin & McKenna


Hey guys! We are Justin and McKenna, your new owners at S2S! We come from Scottsdale, Arizona (originally Wisconsin for Justin) and have been living in Bali for just under one year and three years respectively. We met in November of 2021 at Justin’s gym in Arizona, started dating in January 2022 after Justin found out the guy I had been showing up to class with was indeed…my brother, engaged by June, moved Justin out to Bali in July, and said yes to the dress (gym) in January 2023. Needless to say, and in the words of Arianna Grande…we see it, we like it, we want it, we got it.

We are so pumped to share this fitness matrimony with you and have a lot of fun while doing it! LFG!!!

Fun Facts

Justin used to own a CrossFit gym back in Arizona for 10 years with his best friend, Jake. Check out Blur Fitness if you are ever in Scottsdale, AZ!

McKenna is one to be rivaled with when it comes to dad jokes and inappropriate jokes only 13 year old boys find funny.

Don’t bring peanut butter around Justin…it WILL go missing. (Or cereal). 

McKenna has been living overseas for over 6 years now and visited over 40 countries!

McKenna Irwin

Hey! I’m McKenna and I’m originally from Scottsdale, Arizona, USA. My claim to fame is that I was a Division 2 Collegiate tennis athlete at the University of Nebraska-Kearney and led my team to the University’s first-ever Women’s Tennis Conference Championship Title for the Rocky Mountain Athletic Conference. #humblebrag #washedup. I have always loved sports and working out and in fact…resisted CrossFit for the longest time.

It wasn’t until I was in Amsterdam 3.5 years ago and saw what the CrossFitters were doing in the gym I was going to, that I decided to be like “hey, that looks fun!” So, there it was…it was then that I dipped my toe in the CrossFit hype, and then about one year later I was HOOKED! I was finally able to get my competitive fill and loved the fact that I was always learning something and could have measurable goals/progress.

I have been living in Bali for almost 3 years now and was one of the few expats that decided to stick out the pandemic here. Sad all the discounts and non-existent traffic is gone now, but so pumped Bali is BACK, baby!!!

I am so excited to continue making S2S a place for community and fitness with my super hunky fiancé, Justin. We both have a passion for lifting people up and bringing out their full potential, and can’t wait to shower you with that when you walk through these “doors” one sensual hip thruster at a time.

Justin Fallon

Hey there, I’m Justin! Since starting in this profession in 2010 I’ve worked relentlessly to better myself as an athlete and coach.  As an athlete, I’ve competed with the best of the best in the CrossFit world for the last 10 years. Top placing in numerous events, including reaching the regional level of the CrossFit Games 6 out of the 7 years I competed. I took a short break to do a year of bodybuilding where I placed second overall in my first show and gained immeasurable knowledge outside the Crossfit world that benefited me and my clients moving forward. As a coach I have had the honor to learn/work with so many great coaches over the years. I used what I learn as an athlete and as a coach to build CrossFit gym in the USA to one of the most well known and respected names in the FITNESS community. While competing and coaching countless athletes to a high level of success in-person and remotely I built a second successful nutrition coaching company that has helped hundreds of people on their health and fitness journey. In 2022 I sold my gym and moved with my Fiance to bali to continue pursuing my passion in such a positive, unique, and beautiful place.  

Most of my hobbies are extremely opposite of active. When it’s time to step outside of the gym I like to relax. My top hobbies are golf, camping, motorcycles, fishing, and above all I love hanging out with my fiancé at home and watching a good movie.
