Functional Fitness Gym in San Carlos, CA

Buck Fitness

train Hard. Train Right.

Small-group, coach-led strength and conditioning in San Carlos for adults who want to train with purpose.

This Isn't A Trendy Workout

BUCK Fitness is built for people who want real training, not chaos or shortcuts. 


We focus on disciplined strength training and conditioning — coached every session, capped for quality, and designed for long-term progress. 


If you want to move better, get stronger, and train consistently under guidance, you’re in the right place. 

What Makes Buck Fitness Different

Three people icon.
Small group classes (class caps enforced) 
Black "X" in a circle.
No advanced or unsafe movements 
Four puzzle pieces, three connected, one separate.
Structured programming built for adults 
A checkmark inside a circle of arrows, indicating a process is complete.
Consistency over intensity, always
A person with a whistle around their neck.
Coach-led strength & conditioning 
A chart with bars increasing in height, and an arrow going up.
Clear scaling and instruction every session 

This is not CrossFit. This is not open gym. This is intentional training.

Who This Is For

BUCK Fitness is for: 


  • Adults who want structure and accountability
  • Former athletes who miss training with purpose
  • Busy professionals who want coaching, not guesswork
  • People tired of gimmicks and random workouts
  • Anyone ready to commit to doing things the right way 


You don’t need to be “in shape” to start.  You just need to be willing to show up. 

Our Programs

Our programs work together to develop strength, conditioning, and long-term athletic resilience.

BUILD

Progressive strength training program focused on building foundational strength for long-term results

ENGINE

Conditioning-based training program designed to build cardiovascular capacity

How To Get Started

Every new member at BUCK Fitness begins with a Foundations phase. This allows us to: 

  • Understand your background and goals
  • Teach movement standards and scaling 
  • Integrate you into classes safely and confidently 


Depending on experience, Foundations may include private sessions, small-group onboarding, or a one-month Foundations Membership. 


From there, we’ll recommend the best ongoing membership for you. 


Simple. Clear. No pressure.

Meet Your Coach

BUCK Fitness is owned and coached by Emma Mills. Emma brings years of experience as an athlete and coach, with a training philosophy rooted in discipline, consistency, and earned strength.

My goal is to make each person that steps into BUCK Fitness feel like they have a home here. A place to push yourself past your limit, get uncomfortable and truly bring out the best in yourself and everyone around you.”

We’re over here working hard, every day. Looking back at this last month of training, I can see so much progress. Not only in my lifts, but my ability to push through the hard days mentally. Good days are outweighing the bad… that’s all I can ask for. Just have to keep going

The last month has been ROUGH. Back to back injuries, with the most recent taking me out pretty good. Haven’t been able to squat in way too long, and if you know me you know that is pure torture. So, this is what my workouts are looking like as of late. Hoping by the end of the year I’ll be back to my regular training so we can start the New Year off right.

Accessories are just as important as your main lifts! Here are some of my favorites. This was my “Sunday Funday” workout; a blend of upper and lower body movements. Focusing on control and strengthening areas of weakness. I also did about 30 minutes of mobility to start out. Shoot me a message if you want to join next time ✌️ Here’s the workout: 4x6/6 Box Step Down (grab any weight for these, or go bodyweight) 4x8 Seated Box Jump 4x6-8 Pull-Ups 4x12+hold Pallof Press 4x12 Seated Arnold Press 4x12 Sumo KB RDL (I did also do some heavy trap bar deadlifts since it had been a while ?)

Didn’t think I’d see this day. At least not from the lens I view it through now. 3 years sober. It is truly amazing, what our minds are capable of. Addiction, depression, anxiety, and fear; Love, wonder, happiness, and courage. We don’t choose the first path, usually it chooses us. It takes over and deteriorates your being from the inside, out. But we can choose to change. I chose to change myself for the better, 3 years ago. Every day is a work in progress, but I wouldn’t trade that for anything. I’m a hell of a lot stronger because of it. Just have to keep going ?

It’s easy to get caught up in comparing yourself to others, or a version of you that you think should exist. It’s easy to forget all of the hard work you’ve put in to be where you are today. It’s easy to forget all the hours you’ve spent becoming that “better” version of yourself that you so desperately dreamed of becoming. . . . I watch that first clip of myself and see a completely different girl, inside and out. She was fighting battles every day that nobody would’ve known about. She would’ve done anything to be who I am today. The girl I see now is much stronger, mentally and physically. She is proud, ambitious, happy and confident. Yes, the weight of the barbell has increased significantly, but that’s only where a fraction of my pride comes from. Most of it comes from inside. How I see myself. And how far I’ve come on this journey. Take time today to be proud of yourself for how far you’ve come, and be grateful to keep putting in the work to become even better tomorrow.

If you know me, you know how much I love to cook! Lately I’ve been trying to eat clean and make it fun, so I figured I’d share my creations with you all. (Bear with me while I learn how to make these cooking videos…gotta start somewhere?) I’m not a fan of following recipes, I like to have fun with it and do what feels right! So my “recipe” below will reflect that style. Pineapple Chicken with Rice - Start by making the marinade. I use about 2-3 tbsp of each: soy sauce, rice vinegar, fish sauce and brown sugar. Set aside about 1 tbsp for the salsa. After you set aside a bit, grate in 2 tbsp of fresh pineapple and its juices. -Make the salsa. Dice up 1/2 cup of pineapple, 1/2 of a red onion, 1/2 of a jalapeño, and a bunch of cilantro. Mix together with the reserved marinade and set in the fridge while you work. -Add 2lb of chicken breast (cut it into 1-2in pieces) to marinade and let sit for ONLY 15mins! This is key. The acid in the pineapple will break down the chicken, making it tender and juicy. But if it sits too long, it will fall apart when you cook it! -Get your rice going. Use 1 cup of jasmine rice with 2 cups of chicken broth, a bit of salt and cayenne pepper! This adds some flavor into the rice. It’s a staple for me. -Get the chicken cooking. Takes about 10 minutes or so over medium-high heat. -Once it’s all cooked, make it look pretty in a bowl and ENJOY. (This also keeps very well if you’re meal prepping) Hitting your protein goals doesn’t have to be boring ;)

I’ll be honest, most of the posts on here are highlights from a couple hours of my day. However, the majority of my days lately have been a struggle mentally. Posting highlights can be deceiving, but we all do it. This is just a friendly reminder that what you see is usually 1% of someone’s reality, so never compare yourself to anyone. I’m working my way through and onto better days, and it feels so good. If you can relate, I promise better days are headed your way too. This gym, my family, my friends and my training are what keep me going. The gym is my sanctuary and if you need one, it can become yours too ??✌️

Sometimes it takes two… or maybe 10 tries to get it right. Told myself I couldn’t leave the gym until I hit this lift. New hang snatch PR ?

Haven’t done much crossfittin’ lately… focused on olympic lifts and getting stronger without compromising my body too much. But, Saturdays are supposed to be fun. Haven’t done toes to bar in months, and probably should’ve had some shoes on for this one.

Frequently Asked Questions

Everything you need to know before booking your free trial at BUCK Fitness.

  • Is BUCK Fitness CrossFit?

    No. BUCK Fitness is strength and conditioning–focused, but we are not a CrossFit gym. 


    We use functional movements and conditioning, but we avoid advanced or high-risk movements and focus on structured, repeatable training that supports long-term progress. 

  • Do I need to be in shape to start?

    No. You do not need to be “in shape” to begin training here. 


    All new members start with a Foundations phase, which allows us to understand your background, teach proper movement patterns, and help you integrate safely into classes. Everything is scalable. 

  • How big are classes?

    Classes are small and capped at 12 members to ensure quality coaching. 


    This allows every member to receive instruction, corrections, and appropriate scaling during each session. You will never be lost in the room.

  • What does a typical class look like?

    At BUCK Fitness, we offer two kinds of classes: BUILD(strength) and ENGINE(cardio). Each class is an hour long and includes a warm up, workout and cool down, as well as hands on coaching and constant feedback.

  • Do you offer open gym?

    At this time, BUCK Fitness operates primarily through coach-led group classes. 


    Open gym access may be offered in the future, but it is not the focus of our training model. Coaching, structure, and accountability come first. 

  • I have injuries or limitations — can I still train?

    Yes. Many members train with past injuries or current limitations. 


    Movements are scaled and modified as needed, and Foundations helps ensure we understand what you need before placing you into regular classes.

  • How does getting started work?

    All new members begin with a Foundations phase. Depending on your experience, this may include: 

    • Private Foundations sessions 
    • Small group onboarding 
    • Or a one-month Foundations Membership 

    After Foundations, we’ll recommend the best ongoing membership option for you. 

  • What memberships do you offer?

    BUCK Fitness offers: 

    • Unlimited Group Training 
    • 3x / Week Group Training 
    • 2x / Week Group Training 

    We also offer a Foundations Membership for new members and a limited Transfer Membership for those transitioning from a closing gym.


  • Are memberships month-to-month?

    We offer both month-to-month and commitment options (3, 6, and 12 months). 

    Longer commitments come with better rates, but all members are guided toward the option that best fits their training goals and schedule. 

  • Is BUCK Fitness right for beginners?

    Yes — as long as you’re willing to train with intention and consistency. 


    BUCK Fitness is not about ego or competition. It is about showing up, learning, and putting in the work over time.
