The Alpine Training Center is an outstanding training facility for outdoor athletes who are looking to increase overall strength and endurance. Connie and her team’s workouts are diverse, stimulating, and best of all… HARD! I recently moved away from Boulder, and ATC is what I miss the most as it’s close to impossible to find a gym of equal caliber. The community is full of supportive, kind, and disciplined athletes of all ages and abilities. I cannot recommend this superb training facility more!

While I no longer come to the alpine training center as I no longer live in CO, to this day I’m still searching for something similar. This place formed me into my best self and I was in the best shape of my life. Connie is an outstanding coach along with the other coaches. It created a wonderful community for me and surrounded by people who are passionate about the outdoors. It’s hard work, but the encouragement you get from others is just what you need! I miss it all the time!

I can not recommend the Alpine Training Center enough! Challenging training that pushes your limits with a focus on form, strength building, and injury prevention makes this place a must join for any mountain athlete. Not only are the workouts endorphin producing, the coaches truly care about developing each athlete and creating plans that will enable them to meet their specific goals or overcome an injury. The community at this gym is super welcoming and its a great place to meet ski, climb, and run partners. My life in Boulder would be nothing what it is today, without this place!

Best of the best of the best. I love training at the ATC and love the community of hard working, encouraging people who also train there. Connie is an excellent trainer, and she ensures that all of the other coaches share the same work ethic, dedication and stoke. If youre looking for somewhere to be encouraged and have your goals supported, theres no better place. And its YOUR goals that matter to Connie and the team. Doesnt matter if its a super difficult technical objective, or just something that youre working toward personally, the team is there to support your work and your success.

Connie and the coaching team are incredible. Great training programs that keep the engagement level high while continuing to drive us to new levels of functional fitness. Their dedication to each individual is amazing - working with us through injury and rehab to get us back on track. The classes are fun and friendly and always welcoming to new athletes. Best gym.

ATC is a fantastic place for the mountain athlete, looking to stay fit or prepare for the next challenge. But its also the perfect place for those recovering from injury, or someone who just wants to get in better shape. Connie and her team are amazing! The workouts and specific movements are intentional, yet also accommodating for any necessary modifications. No matter where each person in the class is--from ultra athlete to just trying to build your base--there is a communal feeling of everyone rooting for each person to give whatever their best is at that moment. You definitely cant say that about every gym. And I cant say enough good things about this gym!!! So grateful to have found it when I moved to Boulder.

I have never been a gym person, but a few years ago I started to get injured a lot more doing my outdoor activities. I guess thats what happens in your 40s! So I started going to the Alpine Training Center and have been amazed at the results. Not only am I a much more balanced athlete, I am also stronger, faster, and have more endurance than what I had in my 20s! Its a credit to Connies amazing programming and care.

I cant speak highly enough of the Alpine Training Center! I started training here over ten years ago and its the most special gym I have ever been to. The coaches are very professional, the workouts are always just the right level of challenging and engaging and the environment is super welcoming and inclusive. Highly recommend!

Fantastic people, place and training. Ive only been going for a month and I can see myself continuing to go there not only for the training, but also for the amazing community the ATC has built. Everyone is inspiring and motivating. Im continually impressed by the instructors attention to form and commitment to correcting it. Always challenging, always fun.

If you like to work hard so you can play hard in the mountains, then this is the gym for you. The small-group format is a fun, supportive, and slightly competitive environment that will push you to do your best. Youll never be bored. Ive been going here for seven years and weve never done the same workout twice. The coaches are experts in their field who can accommodate individual goals and fitness levels. I cant say enough good things about The Alpine Training Center.

Ive been going to ATC for a few years now and wouldnt consider going anywhere else. There is such a vast amount of variety and I love the focus on coming seasons, such as skiing, mountaineering and summer endurance. The coaches are always giving it their all and providing feedback on form and effort. Love the people and the place!

I cant recommend the Alpine Training Center highly enough! It is exactly the gym I had hoped to find in Boulder... and I gym hopped until I found it.The workouts are challenging-- but also smart and well designed. Every movement has a purpose and is designed to make us stronger in our sports outside the gym. (And it works! I wouldnt be able to run ultras without the strength, mobility, and stamina I gain at ATC).The community is friendly and supportive and the small group size means you are never overlooked.

The ATC is an amazing gym for anyone who wants to optimize their time playing in the mountains - biking, skiing, running, climbing - and be part of a super supportive community! The coaches are so inspiring, knowledgeable and know how to push each athlete to their personal best. The small classes mean it’s never a one size fits all approach. When I broke my ankle last year, Connie created workouts for me so I didn’t fall too far behind while still in a boot. They care about your personal goals and have the workouts to help you achieve them!

I’ve been curious about this place for years and finally scratched the itch. It’s terrific—extremely supportive and friendly. The workouts are challenging and it helped that I have past experience weight lifting. But even if it was all brand new, it wouldn’t be a problem because Connie and her coaches are extremely knowledgeable and patient. Perfect for someone who is self motivated and eager to improve.

The Alpine Training Center is the best gym on the Front Range. Connie and her staff have created a welcoming but motivating environment that challenges everybody. Superb programming, excellent attention to form and quality. If you want to take your skiing/running/biking/climbing to the next level, or just want to feel good and strong, then you want the ATC.

ATC is the best training you will get period! Connie is the reason I am injury free and can go up and romp in the mountains and suffer less. Great community with like minded friends and a ton of fun!

ATC is my favorite gym in Boulder. The workouts are always changing. The coaches are supportive and motivating. Its not easy, but its rewarding. The people that workout there are awesome. Great crew, great place!

Such a great gym! The workouts are intense but manageable for all skill levels. The coaches are top notch, and the programming is perfect for building power and resilience in the uphill and downhill athlete. The people who come to this gym are warm and welcoming and have a great community here.

If you climb, run, ski, or bike and want to gain strength and fitness this is the place for you. Workouts are sport specific. The coaches are awesome and athletes are suportive. Most important is that it is a community of like minded people who will welcome you as part of the tribe when you when you walk in the door.

Connies gym is truly a one-of-a-kind experience for anyone trying to get back in shape, improve their athletic performance, or train for their next outdoor adventure! The coaches and gym community are highly supportive and motivating – I cant think of a better place to work out and be pushed beyond what I could achieve individually at the gym :-)

Serious workouts for people serious about being in shape for serious sports...seriously. Structured programming tailored to the kind of hard stuff we like to do, but constantly varying, never a dull moment. Connie and her coaches dish it out day after day, physically and mentally. The people who work out here are also amazing and supportive--its a great community.

Awesome spot to train with a great community of mountain athletes. Challenging well structured workouts push you to get better and highly knowledgeable coaches provide tips on form and technique and of course motivation! If youre looking to get stronger on the trail, skin track, or rock this is the place to train!

Alpine Training Center is a top level local gym. All of the coaches are super supportive and motivating. The community becomes your community of like minded people looking to get strong and healthy, They will cheer you along the way.

This is the best all around training center for mountain sports! Ive noticed a huge difference in my climbing and skiing performance since Ive started coming (around a year). Connie and staff are incredibly knowledgeable and create thorough workouts that progress through various themes to build an all around great strength. ATC is a great community and fun place to get strong!

Positive, supportive, hard working environment with quality gear, fun/diverse workouts and awesome coaches/trainers. Highly recommend!

Fantastic coaching and community. I’ve trained at a lot of gyms, but the programming that Connie and her staff put together is second to none. This is the most complete hour of fitness you’ll find.

This place is incredible! I cannot recommend this gym enough! The trainers and the workout programs are amazing! The community here is so supportive, kind and encouraging!

Ive been going to ATC off and on for about 10 years now. The thing that love about it is the variety of programming, I really dont think Ive done the same workout twice! You never know what youre in for on a particular day but you are guaranteed a great workout that will push you. The coaches and community are all very supportive; even if you are not a uber athlete like me! The people, the variety and the 1 hour time commitment keep me coming back!

The ATC has helped me to transform myself as a mountain athlete. The instructor to participant ratio, as well as thoughtful programming allows for individual critique throughout sets. Their programming accurately caters to each individual’s fitness goals, whether it be climbing, ice climbing, ski mountaineering, or maintaining general fitness for an active outdoor lifestyle. Aside from exceptional trainers and top notch programming, you will also find community in like minded people. Outside of digging deep and grinding for an hour session, Connie, the lead coach and founder, coordinates day outings and volunteer work outside of gym hours. Occasionally, they will host guest athletes or experts to share their knowledge on specific subjects such as nutrition or recovery. If you’re looking for a gym in the Boulder area, then sign up for a session to see if it’s for you. Come prepared to push yourself!

The ATC is the best endurance training center in Boulder. You know you are in the right place when you look forward your training sessions even though it’s going to be a suffer fest. The community is awesome and the coaches are top-notch.

Love, love the ATC! Connie is an amazing coach who is tough, but encouraging. She asks about your fitness/adventure goals and she holds you to it. She trains you to meet your goals and stay injury free. Training at ATC has made me a tougher athlete mentally and physically. Love the community that Connie has built.

If youre an outdoor athlete, spending some time at ATC is probably the best investment you can make towards your favorite activity, whether you want to get to the next level, reduce injuries, or simply increase your fun in the mountains. The workouts are constantly changing and always challenging. Connie, Jason and the other coaches are great at getting to know each participant, their goals and abilities, and making sure each workout works for them. More importantly, theyve done an incredible job at creating an environment where people push themselves and are supportive and encouraging of each other. No matter your age or fitness level, ATC is a great gym where you feel like you belong.

Ive known the owner, Connie, for about 5 years and have been going to classes here on and off since then. This place is hands down THE BEST place to train in Boulder and there are no better coaches to kick your butt than the ones here. 100% the BEST!

When I moved to Boulder, I did the gym-hopping thing for a while, until I found the ATC! Great programming, and fantastic caring coaches. I would never push my self this way on my own, totally worth it.

Ive been going to the ATC for a few years now and I love the programming and the coaches. Every workout is different. I love the community that Connie has built and I look forward to seeing everyone each time I go. I started going for shoulder rehab and general injury prevention and it made a huge difference in my recovery. I have never been a gym person but I do love going to the ATC!

Connie and the ATC are the closest thing to a home away from home you’ll find in a gym. Amazing programming, amazing community, and if you come ready to work Connie will make sure any goals you have you’ll meet.

Ive been an on-and-off ATC-goer for almost two years, and theres a reason I keep coming back! Connie and the team take care of every individual athlete here. I broke my wrist two months ago and have still been consistently engaged, training in ways that do not aggravate the injury. The programming has made me a stronger, more complete athlete. I play a lot of soccer and I feel when I am consistently putting in the work at ATC I am way less likely to get knocked over, get injured, or feel sore after matches.

Connie and her team at ATC design incredible, fun, well-balanced workouts that challenge me and make me stronger, faster, and ready for big objectives. The community at the gym is also incredibly supportive. If you have a passion for mountain sports, ATC is definitely the right place to train!

This place is the best! Great community and it keeps me fit for doing all the stuff I love to do outside.

Best. Gym. Ever! Whether you are training for something specific, returning from an injury, or are brand new to working out, Connie and the amazing team at the ATC will help you get to where you want to be in a fun, no judgement, environment. The community is top notch and you will make lifelong friends!

Amazing trainers, tough workouts that make me stronger, fantastic community!

Connie and team have built not only a world class training facility but also an incredibly thoughtful, tight knit culture of athletes that care about performing at their best in the mountains.

ATC is a great community and the coaches are all wonderful. Love my morning crew with Mike and Connie leading

I love this gym! I have been going here for about five years and I refuse to train anywhere else. The ATC is easily the best gym in Boulder!

ATC, and Connie (& coaches) have created an incredible community of inclusion, motivation, friendship, and zero BS. Im seven years in and cant even imagine going elsewhere.

Amazing community of people who like to work hard and play hard! The ATC programming has kept me ready for any mountain adventure!

I love this gym. The regular climbing workouts are just the thing to keep me in shape and prevent injuries.

The very best functional, no-frills cross training for outdoor athletes. No mirrors, TV’s, or gym rats - just a different solid workout every day, designed to build functional strength for mountain pursuits alongside a like-minded community. The winter skimo program is a highlight for any backcountry skier. I’d give Connie and crew 10 stars if I could! I feel so fortunate to have the ATC here in our local community.

Boulder has many great gyms…and I’ve tried many of them. But the Alpine Training Center is exceptional in all regards. Great coaches + Great workouts + Great community.In terms of programming, it’s high intensity interval training. (like Crossfit, but without the CrossFit®-is-my-identity-and-life culture.) In five years of training 3x per week, I don’t think we’ve ever repeated the same workout twice. Never boring. Sometimes quite hard. Always fun. You’ll probably have the best body of your life.The gym attracts everyone from beginners to elite athletes. Regardless of skill level or background, the ‘ATC’ is extremely welcoming. No ego. No attitude. No cliques. No bros. No showers. But lots of nice people in lots of different body shapes. It’s simple and basic — You show up to work hard and then leave feeling pretty darn satisfied. Along the way, you’ll probably pick up some great friends.The Alpine Training Center is not for everyone. Looking for smoothies? Go to Jamba Juice. Want to stare at your swole bod in a mirror post-workout? Perhaps cruise past IKEA on the way home. Need lots of branded gym merch to feel committed? Well, we all know where to go for that.But…. If you’re looking for a great gym to push hard, get in great shape, and make some good friends — The Alpine Training Center is the place!

ATC is the perfect complement to an active [Boulder] lifestyle.The ATC is the epitome of adventure enablement! ATC translates to any activity... whether its your favorite or one youve never tried before. ATC pays dividends when it comes to injury prevention and the backcountry .The best part about ATC isnt the workouts -- which are AWESOME -- its the people!!! The positivity and encouragement is second to none!Come join us...

Honest review: After almost a year of going to the ATC, none of my shirts fit right because the muscles in my arms are perfectly sculpted and my biceps are much bigger.

I can not speak highly enough of Connie, the coaches (Jason, Mike, Mellisa, Savanna, etc.), and the programing at ATC. If you are a mountain athlete, you need to be training at the ATC.

Great coaches and a terrific community of mountain athletes!

Amazing complement to all of the outdoor sports.

Change your gym, change your life.

Connie is awesome!

The most amazing place to train in Boulder, hands down!

I will not train anywhere else! This is hands down the best place I have ever trained. Connie, Jason and Mike are just incredible. This no frills gym is perfect and knows how to get an athlete in top shape!

Amazing place to train and be part of! The owner Connie really knows her stuff and puts together incredible workouts!

Connie showed me I could do much more than I thought I was able to. Custom workouts for climbing were what I needed and ATC delivered a well rounded strength and endurance work-out that helped tremendously. Visiting ATC opened me up to HIIT and helped me work out on my own in a smarter and more focused way concerning my sport. Thanks, Coach!

Great people and a great place to get your butt kicked

Connie is the best at what she does. Be prepared to work and hurt but its so worth it.

Great place for a serious workout

No better place to whip yourself in shape!

Great area, great vibe
