Aviv is another Croga member that has shown just how far you can get with focus, consistency and dedication. Over the last 3 years he has made some HUGE improvements in every aspect of his fitness, most notably his strength, coordination and endurance. One of my favorite things to experience as a coach is meeting a new member that is obviously very disciplined and analytical in their career, and seeing them apply those same characteristics to their health and fitness. When they do so, they are basically unstoppable and Aviv is one of those people and his results show in a relatively short people of time show it. I loved it when he signed up for Croga Nutrition and within months he was absolutely shredded, it was incredible! Finally, one of my favorite things about Aviv is his friendliness with new members and his willingness to help others either in class or outside of class with their nutrition. Aviv was our first really successful vegetarian nutrition client and whenever we have a new vegetarian sign up for Croga Nutrition, we always lean on Aviv for his wealth of knowledge to help these clients get off to a good start and he is always more than willing to help. Thanks for being awesome, Aviv! We love having you at Croga and can’t wait to see what you accomplish next.

When did you join Croga? 

I started in October of 2018 after coming back from a canyoneering trip with a good friend to Zion National Park. He was just in tremendous shape and when I asked what he did to keep fit he told me he did crossfit. That was the first time I had heard of it. Because I was dying during the hikes and he wasn’t I promised myself that whatever he did I’d try too. 

What were you doing before for fitness? 

Some running. Some lifting. Honestly, it’s not even worth mentioning. An injury-prone waste of time. I’d been better off doing nothing. 

I sometimes see people jogging on the street trying to get fit. I have a strong urge to tell them to stop wasting their time and head over to the nearest crossfit box. 

What was your first workout? First reaction to your first workout? Of those first workouts the one that I remember the most is Mary. It’s hand-stand push ups, pistols, and pull ups. And the pistols just ruined my legs.  I remember not being able to walk right for three days afterwards. I also remember almost barfing on those short 7 minute mini-wods that you do in the orientation, and coach Dave bringing another band and another band for me to do pull ups. Oh, the humiliation. 

In fact, the entire first year I was in a solid state of DOMS. I’d wake up in the morning with everything hurting and go to sleep at night with everything hurting. In my imagination I pictured the Croga coaches offering me a red pill and a green pill. Take the green pill and go back to your sedate existence. Take the red one, start training, and realize that you’ve never actually used your body in a meaningful way. 

What days and times do you come to Croga? 

For a long time I had a routine of Sat, Sun rest Mon, Tue, Wed, Thu, rest Fri, and I’d come in for the 5 am workouts. So during those o-so-many grueling months in the beginning I’d tell myself (more like chant it like a mantra) that I just had to survive through two days of workouts (Thu is oly lifting which I could muddle through more easily). 

Then during covid a bunch of us had a 7 am zoom garage workout which I attended regularly and which helped keep me sane and fit. Now that we’re back to normal I attend the 6 am workouts and on days that I can’t make 6 am for whatever reason I come in at 3:30 in the afternoon. 

I also don’t take scheduled rest days anymore. I find that between regular camping trips with my family and life intervening in general I get a sufficient number of rest days imposed on me. So I workout as much as I possibly can when I’m in my routine and when something comes up and I miss a workout or two I don’t stress about it and simply take it as an opportunity to recover. 

What improvements have you seen in the way you look, feel and perform? 

I am much leaner and stronger now for sure. And not to sound too superficial, but it is nice to be able to take my shirt off in the pool or wherever and not feel ashamed of how I look. Equally important I love knowing that whatever I decide to do, hiking, running, mountain biking, I’m ready. I can jump in and not worry too much about being out of shape, even if I don’t train that specific sport regularly. I also love knowing that I won’t pull my neck or throw my back out trying to lift a potted plant or my mother in law’s suitcase or some other BS. Training regularly has made me much more resilient in that respect. 

What’s your favorite post-workout routine? 

After flopping around on the floor gasping for breath like a fish out of water I go to my car and open all the windows. And on that drive home, summer or winter, I blast the music and let the wind blast through the windows. Best few minutes of my day.   

What’s been your favorite culinary discovery since joining Croga? 

Not a culinary discovery per se, but Croga Nutrition has been an absolute game changer for me. Eating according to the program has had a bigger impact on my health and well being than the workouts. I can say that with confidence because after a year of working out I had actually gained 20 lbs and was fatter than ever. I gained a lot of strength that year too, but you wouldn’t know it by the way I looked. After joining the Croga nutrition program I lost 40 lbs and started recovering much faster from the workouts, which I attribute to the optimized nutrition.  It’s been two years now that I’ve been tracking my macros and eating according to the program and I have no plans of ever stopping. I love having control over my intake and being able to adjust it according to my fitness goals. 

What do you love about this type of fitness? 

I love the intensity. After doing crossfit, anything else feels like you’re not even moving.

I love that the strongest athletes in the gym and the noobest of noobs can train together, doing essentially the same workout with some minor modifications, and it can be challenging for both of them. 

I love that so much of the workout is just a mental game against yourself. To quote Dr Suess: “Sometimes you’ll play lonely games too. Games you can’t win cause you play against you.”

And I love the camaraderie that comes with doing really sucky things together. That friendship got us all through more than a year of covid. 

What’s your biggest fitness goal for this year? 

This will surely take more than a year but I’d like to be able to do workouts at Men’s Rx consistently. I’m not really even close yet, and getting there will require increasing my strength significantly. So I’m going to keep my eye on the prize and continue training, and cutting, and bulking, and doing whatever the coaches tell me do to until it happens. 

“The Aviv” WOD! What would it be?

“Ignis aurum probat” (fire tests gold)

Partner workout, 3 RFT

40 Assault bike calories

40 Power cleans 135/95

40 Pull ups

I love partner workouts. Either you’re a little bit slower than your partner, in which case you get the workout of your life trying to keep up, or you’re a little bit faster, in which case you get to encourage your partner, pick up any slack, and generally feel good about yourself. Either way you win. And I hate complicated workouts. Any workout that has the word “then” is on my stink list. Or when the workout is actually hidden in the fine print of the extra instructions. Nope. Give it to me straight. I like it when I can tell what to do from a single glance. I also like classic crossfit workouts where there’s a monostructural component, a gymnastics component, and a strength component. Finally, at some point Coach Dave was talking about a workout (I can’t recall exactly which) but I loved how he described it:

My arms are on FIRE

My legs are on FIRE

My brain is on FIRE

I am riding a bicycle through HELL

So he gave me the inspiration for this workout. 

What words of advice do you have for new members or people considering joining Croga?

“I don’t look like an athlete”. “I don’t know the moves”. “The other guys are way stronger”. “I’m afraid of making a fool of myself”. “It’s really crowded. I’m sure I’m getting in peoples’ way”. Nobody cares. If you think anybody has even half a brain wave to devote to judging you, you are mistaken. People have their hands full just keeping themselves alive during the workouts. So get it out of your head that anybody is judging you. Whatever you look like, whatever level you’re starting from come on over and the coaches will get you fit while keeping you safe. 

There is nothing more humbling pushing yourself to the edge and discovering that you are not as strong as you thought. Conversely, there is nothing more rewarding than lifting a weight or a mastering a movement that was previously unattainable. Come to Croga and experience both.

David Musgrave



From a very young age, it became apparent that Coach Dave loved all things sport and competition related. Maybe it was being the youngest of four or maybe it was being the only boy in the family. Whatever it was, it has created a fire inside of him that fuels his urge to constantly be striving for excellence through consistent and steady improvement. His unwavering persistence and eternal optimism are his two greatest assets as a husband, father, coach, entrepreneur and athlete. They are the pillars he has stood on for as long as he can remember and are the reasons he is such a fantastic leader. He grew up playing competitive soccer, loves snowboarding and enjoys traveling the world. Dave was thrown into the world of CrossFit in 2008, he has competed in the largest competitions in the CrossFit world and in 2017 he was the 18th Fittest Man in Northern California in The CrossFit Games Open, finishing 34th at the California Regional as an Individual Athlete. Dave relocated to Boise, ID with his wife and two daughters but still has a hand in directing the heart of Croga Fitness. When he is not coaching or training, you can usually find him reading a book, listening to a podcast, doing some online continuing education or having a chat with someone he thinks he can learn from. As a very curious, driven and dedicated individual, he like to say that he is a serial learner and has an unquenchable thirst for knowledge. Over the years, Dave has experimented with a lot of different types of eating, but never really felt like he was in control or consistently making the correct food choices that would result in long term success until he found WAG and “flexible dieting”. Dave and his wife have both had significant success with improved body composition and performance since incorporating this healthier and more sustainable type of eating into their lives and it has inspired Dave to want to share with others and inspire them to improve their health through flexible dieting as well.

Ethan Fein



After trial runs at baseball, fencing, and soccer lasting two seasons, a couple years, and one practice respectively, Ethan found ice hockey at nine years old and was immediately hooked. Wanting to get stronger going into his freshman year of high school in 2016, Ethan started working out at Croga, where his mom, Julianna, was already a member. CrossFit became a separate passion, rather than just a supplement for hockey. Now a freshman at UCLA, the pandemic delayed Ethan’s move to southern California and allowed him to focus on other interests. He has always been interested in the mental side of sports and as someone who loves watching sports, he enjoys learning the nuances of each game. Becoming a coach has given Ethan a different perspective on CrossFit as an athlete and a chance to help others improve and reach their fitness goals.

Turning Point

I am a D1 volleyball athlete turned recreational rugby player turned mediocre disc golfer. After leaving college I had no idea how to take care of my body or my nutrition. Then at 23, I started what would become a 7+ year battle with cancer and my body was just falling apart. 5 years ago, in between rounds of chemo, I found CrossFit. The diverse workouts kept me excited, the community kept me showing up, and the rest is history.

Motivation & Passion

I truly just want everyone to be as excited about movement as I am. Sure is the competition side of CrossFit fun and exciting? Yes. But there is nothing like discovering the power inside yourself to positively create change within your body, within your life. That feeling from when you’re 6 years old and you make it across the monkey bars the first time does not go away. Whether it’s cross-training for athletics, trying to keep up with your kids, or getting in the best shape of your life at age 50, I want to be a part of that journey for members. That’s why I coach, and that’s why I show up at the gym (almost) every day.

Member of the ROGUE 750# CLUB…woohoo!


I’ve been interested in the human form and movement for as long as I can remember and decided at University to get serious about learning it! I’m a practicing Physical Therapist, fitness coach and mama of three. Those little rascals are by far my favorite and greatest motivation. Some of my interests include: playing the tenor sax, anything water-sport (including sailing), horseback riding, racquetball, dancing, wine tasting …and fun!

Turning Point

I was a boxer and broke my hand in the ring. While I was post-surgical, in my cast and feeling sorry for myself, I started focusing on strength training. After a couple of years and noticeable progress, I decided to try out CrossFit.

Motivation & Passion

When people come together, support one another and get health benefits that surpass conventional outcomes by moving better and working hard..well then we’re on to something. CrossFit facilitates this AND gives an opportunity to all, athletes and coaches alike. Getting someone moving better and proud of their own achievements / progress is my motivator. I may not get them to their finish line, but if there is an opportunity along their journey I can educate, coach and push them, oh…I’m there!

Back Squat-350

Deadlift- 405



Work as a project manager for a general contractor by day, and throw weight around at my favorite gym by night. I love working out, I want to share my love for working out with everybody and hope it rubs off. It is the best natural medicine for anything. The more people realize that the happier our lives will be.

Turning Point

I have a passion for sports and working out. I want to share that passion with people, and hope it gives them what it has given me throughout the years. I wasn’t able to do that while working as a project manager, I was blessed with the opportunity to do so at Croga and it has been very fulfilling.

Motivation & Passion

I want to see people live happy lives, and one of the best starts to do that is feeling like the best version of themself. Going to the gym and having fun a few days of the week is a step in the right direction.

Nicolas Tran



As the younger sibling of an older brother who was well rounded in sports, Coach Nick was always surrounded with opportunities to dabble in all kinds of sports. He became a multi-sport athlete in wrestling, track and field, volleyball, and was the captain of his varsity football team. As a result of playing all of these sports, Coach Nick found his love for how versatile the human body is from his football coach.

Turning Point

From then on, he wanted to pursue a career in physical therapy so that he could have the opportunity to help people and guide them down a path of living a longer and healthier life. Coach Nick worked as a physical therapist aide at numerous clinics in San Jose and wanted to broaden his horizons with more hands-on training. He looked at gyms and came across Croga Fitness that had a loving community and the rest is history!

Julia Muller


Deadlift 265#

Bench 137#

Squat 205#

Snatch 105#

Clean 140#

Jerk 150#


I am a fitness forward physical therapist and coach with a passion for helping people move better, feel better, get out of pain, and hit their PRs. Being able to share my PT experience with athletes is one of my biggest joys. I am originally from the northeast (Boston area and central NY state) and started coaching while in grad school. I fell in love with group functional fitness for its ability to challenge me both mentally and physically. The communities were unmatched and seeing athletes of all ages achieve new heights was captivating! I wouldn’t be where I am today without the support of incredible coaches and mentors. I also grew up a competitive swimmer for over 17 years and have recently gotten into long distance running outside of functional fitness.

Turning Point

When I first started group functional fitness at various gyms back East, it was the first time I ever felt welcome in a lifting atmosphere as a female. Having incredible female coaches was what kept me feeling safe and welcome in the gym. I never thought I would ever have enough experience or confidence to lead fitness classes. As I started taking more lifting specific continuing education in PT school, I realized that I had the knowledge to be the female role model that I had. I hope that other female athletes can feel confident and a sense of belonging in gym spaces.

Motivation & Passion

I am passionate about supporting people with their fitness across the lifespan. I have specialized experience and interest with fitness during pregnancy, postpartum as well as with geriatrics. I love being able to use my PT skill set in the gym to modify workouts appropriately and help athletes feel like they are still performing at their best. I am too aware of the negative health effects that lack of physical activity can have on all systems of the body and it is my mission to help athletes feel welcome and supported with their fitness journeys.

Along with his brother PJ, aka “The Brother’s Rubel”, he found CrossFit in 2011 and immediately fell in love with the challenge that each day presented and also how great it was having a supportive community of like minded athletes helping you along and cheering for you to be successful in your pursuit of improved fitness and health.
