Want to Learn Olympic Weightlifting? Now offered 2 times a Week!

Our barbell class has always been the most popular class of the week. The Sn**ch and Clean & Jerk, the sport of Weightlifting, it’s just so addictive. I relate it to Golf because both the swing and the lifts are so technical. It looks so easy but when you try it, you immediately realize how much technique there is to master. It challenges us mentally and physically!

We’ve been coaching these complex lifts for about 17 years. None of us are competitors so we’ve learned how to lift for longevity. That’s why we breakdown the mechanics and technique so much. It isn’t about how much you can lift, it’s about learning the WHY in the technique, and the HOW it works with the right muscles.

This is the best Weightlifting class in town! (Even though we are the only one 😜) but I can guarantee we are the oldest. In all seriousness you can come in to learn with no experience and at any age. Our community of lifters range from 14U teens to 70+ year old. We can all learn to lift together because we focus on teaching the mechanics and not just chase numbers.

Contact Mark Sun if you have any questions. If you love to lift but stopped due to injury(very common) hit Mark up.

Weightlifting Class
Wednesday at 6pm
Saturday at 9am

Being fit in the gym doesn’t always mean you’re ready for what you love doing outside of it. Achilles, ACL, Meniscus, Low Back Injuries Oh my… You know exactly what I mean. We are “Old” now but this isn’t the end of our active lifestyle.

A lot of the athletes I coach don’t necessarily love working out. They train because they love jiu-jitsu, hockey, basketball, tennis, surfing… that’s their outlet. The gym helps them keep doing it.

But gym training and sport training have different demands. You can be strong and have great conditioning, but how often do you train rotation, absorb force, or react and change direction?

That’s what we’re working on in Athlete for Life.

We’ll use our PEMDAS formula to build those movement patterns together, with two classes a week to practice and keep getting better.

Come try it out this week!
📅 Wednesday at 5pm
📅 Saturday at 8am

Included in your CrossFit Sun membership, or you can join with an Athlete for Life only membership.

What do you love doing outside the gym? Let’s keep you doing it. DM me if you have any questions! Mark Sun

Thank You all for coming out, those that messaged, everyone who supported, all the volunteers, and most importantly, everyone that has been part of the CFS Community over the last 17 years.

So many good memories and life long connections made at this gym. This community, the people, it’s such a unique experience.

No matter what timeline or which years you were part of this journey, thank you! The community is special because of everyone that is a part of it.

This place is too special to not fight for it. I will continue to do what it takes to keep this community going for as long as possible!

I am grateful to everyone I’ve met through CFS over the last 17 years. 🙏 ~ Mark Sun

ARE YOU WORKING OUT… OR TRAINING FOR LIFE?

Sweating isn’t the goal.

Burning calories isn’t the goal.

Losing weight isn’t the definition of fitness.

Those things can happen along the way — but CrossFit was built around a much bigger idea:

Prepare the human body for whatever life demands.

Endurance.
Stamina.
Strength.
Flexibility.
Power.
Speed.
Coordination.
Agility.
Balance.
Accuracy.

Most of us naturally gravitate toward what we’re already good at. Runners run. Lifters lift. We find workouts we enjoy and repeat them.

But life doesn’t let us choose the test.

Sometimes you need strength.
Sometimes balance.
Sometimes endurance.
Sometimes speed or coordination.
And sometimes you need several of them at once.

That’s General Physical Preparedness.

At CrossFit Sun, we’re approaching 17 years as a community.

We’ve watched fitness trends come and go.

New workouts. New equipment. New programs. New promises.

But after nearly 17 years, the thing that matters most isn’t the trend.

It’s your quality of life.

Can you keep doing the things you love?

Can you learn a new sport?

Can you play with your kids and eventually your grandkids?

Can your fitness give you more options instead of fewer as you get older?

That’s why we don’t want to be great at just one thing.

Build capacity across all 10.

Be ready for whatever life demands.

That’s fitness.

Fitness is infinitely scalable.

Same class. Same community. Same goal.
Different athletes. Different abilities. Different versions of the movement.

Scaling isn’t making fitness easier. It’s meeting you where you are and continuing to move forward.

Start where you are. We scale from there.

If you’re ready to start or restart your fitness journey, come try a FREE class!
