Josep Baixas, founder of Build for the Mountain

Hey, I'm Josep.

Build for the Mountain is just me. I'm a coach, and I ski, climb, hike and head up mountains every chance I get.

Here's what I see all the time: people who live for the mountains but don't train until something hurts — then start from below zero. Others train hard, but for the gym, not their sport. And many are too busy, or too buried in information, to know where to start. Sooner or later, they start feeling it — more rest days, more stops on the way up, and a body they don't quite trust anymore.

I know the feeling. When I started skiing seriously, my knees and lower back were killing me. And it made sense: I'd never properly rehabbed my ankle sprains, and my work–couch–bed routine (with the occasional stretch or 10-minute knee fix) wasn't exactly getting me ready for the chaos of the mountains.

Every season I paid the price: the pains stacked up, I couldn't push as hard as I wanted, and it was getting harder to enjoy the mountains as much as I used to. My body was setting the limit.

So I learned my way out — from education, great mentors and a lot of trial and error on my own body. Now I help others find their way out too.

Here's what I build for you: a training program that adapts to your body, your mountain sport and your life. We start with whatever's holding you back — joint pain, mobility, strength, or all at once — and step by step, build you up until you stop for the view because you want to, not because you need to.

And you don't do it alone. I write your program, review your form every two weeks, get on a call with you every month if you want one, and answer your messages myself.

If you're ready to do the work, book a free call below.

Skier · ACL, MCL & meniscus injury

“I no longer feel pain. And I can push harder than ever.”

Read their story

Four years ago, I injured my ACL, MCL, meniscus, and kneecap. It was tough, but around three years ago I started working with Josep — who not only guided me, but truly motivated me to recover and get back to what I love most: skiing. We started from zero. Alignment, mobility, building a solid foundation. Once that foundation took shape, we moved on to strength and more mobility work. And as I improved, he kept raising the intensity of the training sessions. Now here I am, doing some seriously tough workouts and seeing progress every single week (especially in the mountains!). I no longer feel pain. And I can push harder than ever. Thank you, Josep. See you in the mountains

58 · mountain biker, skier, kitesurfer

“Over six months now and it is working great! NO training injuries. I feel strong and stable on both my mountain bike and skis.”

Read their story

I am a little more than a weekend warrior athlete - 58 yrs old, 4 children and a full time job. I go hard mountain biking, skiing and kitesurfing. … Historically I go too hard, too soon and end up hurting myself and not making or seeing gains. I have issues with a shoulder and one knee. … Over six months now and it is working great! NO training injuries. I feel strong and stable on both my mountain bike and skis. Recovery is never an issue. My new strength and joint stability are allowing me to progress well in all disciplines. 'Pushing the envelope' more than I have in the past. … Slow and steady wins the race every time!! Thanks Josep!!

Hiker & climber · Nepal trek

“Of course leg muscles were from time to time sore after many days of hiking, but I had literally zero joint issues.”

Read their story

I am coming back from my trek in Nepal, it was great! I really feel the training I did before the trip was super useful. Of course leg muscles were from time to time sore after many days of hiking, but I had literally zero joint issues. I was also worried about the back, since I carried a quite heavy backpack every day and in the past it was a problem. This time zero issues! Now I am even more motivated than before to continue with the training 💪💪

Skier · overuse injuries

“I was facing routine overuse injuries and was feeling the brunt of skiing year over year on the body. Working with Josep changed that significantly.”

Read their story

Before I trained with Josep, I was facing routine overuse injuries and was feeling the brunt of skiing year over year on the body. I was pretty fit, but saw a difficult future ahead. Working with Josep changed that significantly. He was able to quickly identity areas of weakness and change my training style so I can have a long life of skiing ahead of me. I also just feel stronger day to day. I have way more toddler carrying endurance than I used to and find that I wake up feeling good, not stiff. … On top of all that, I really just enjoy it. He designs a good program. He's fun to work with.

Hiker · IT band issue

“I was able to add 4 pounds of lean mass to my legs (according to my Dexa scan) through his program.”

Read their story

Before I joined the MFT program. I was struggling with an IT band issue. I felt very imbalanced. Josep helped me find that balance again by focusing on hiking specific exercises. I feel much more mobile and much stronger as well. As a matter of fact I was able to add 4 pounds of lean mass to my legs (according to my Dexa scan) through his program. Josep helped me get back to the mountain and be in tune with my body than I have ever been!

Glacier guide, skier, mountaineer, climber · torn ACL

“All the training done has been translated into strength on climbing and hiking, and everyday life improvements and movement in general.”

Read their story

My thoughts of starting with this program came after my knee injury in February. I never really trained before for my mountain sports, but was just going to the mountains and that was keeping me fit enough to keep doing it. … I could see the results from the week one. I've had feedback in every exercise and he's adapted them according to my needs, time, space, and gear needed (I've got no gym facilities so all my training has been at home with elastic bands and few weights). … I've seen improvements every week in the exercises, and especially in my activities and work (yoga, ice climbing, climbing, working on the glacier/hiking…). My awareness and control of my body have levelled up considerably all these weeks … All the training done has been translated into strength on climbing and hiking, and everyday life improvements and movement in general. … We want a strong body that will enjoy and last for a long time in our mountain life! And Josep will surely help you with those goals.

Hiker · joint pain

“I think the biggest win from joining is that I'm learning to work with my body. I'm learning to trust it and love it again.”

Read their story

I have an autoimmune thyroid disease, and together with the medication I'm taking, I started experiencing a lot of joint pain all over my body. A few months ago, I began searching for some kind of rehabilitation or solution and stumbled upon MountainFit on Instagram. I love walking, hiking, and staying active, but all of that was becoming harder and harder as the pain kept getting worse. … The program is tailored specifically to me and my needs. … He met me where I was and helped me grow from there. I can always send him a message or a video for review, and I get a reply in no time—20 out of 10 support. … I can hike longer and more often, and if I slip, it's so much easier to keep my balance. I never really liked working out before, but now I actually miss it on rest days. I love it. … I think the biggest win from joining is that I'm learning to work with my body. I'm learning to trust it and love it again.

“I felt the strongest and the healthiest in a long time.”

Read their story

I stumbled upon Josep after a year trying to rehab myself from various injuries. I was out of shape and fragile. I must say the results I achieved with his lead really surprised me. I felt the strongest and the healthiest in a long time. Even tough he's very young he is so knowledgeable and a real pleasure to work with. Worth every penny in my opinion.

FAQ

Questions

Is this for me?

If you live for the mountains — and want to push harder, or just keep doing it for as long as you can — yes. Whatever your age or starting point.

I'm not injured. Why would I train?

The mountains wreck your body. You probably know that. For a lucky few, the sport alone is enough. For most, it isn't. Training is your insurance: it hugely improves your odds of doing this for life, and cuts your odds of getting hurt. Your call.

I already go to the gym / do yoga. Do I need this?

Honest question: how's that going? If you're still dealing with pains or holding back out there, something's missing. This is built for the mountains and for your body. If you're looking for that extra, this is it.

I did physio and I'm cleared. Isn't that enough?

Physio usually gets you feeling good for daily life. The mountains ask for a lot more. This bridges the gap — from cleared to feeling like a rocket out there.

Will training cost me time in the mountains?

It takes some time, yes. But we don't plan your sport around your training — we plan your training around your sport. The mountains come first, and every session is built to get the most out of the least time.

How much time does it take?

I recommend 3 sessions a week, 45–60 minutes. Less or more works too — it's all adapted to you.

Do I need a gym?

No. Your program is built around what you have — dumbbells, bands, or a full gym.

Does online coaching work if you can't see me train?

If you do your part, yes — the results speak for themselves. Every exercise has a detailed video demo. I review your form in regular form checks, you can message me any day, and we can get on a call every month if you want one. I make sure you're doing the right thing at every step, so you progress as fast as possible.

What if something hurts during the program?

Tell me. I'll look at it and adjust as needed — so you can manage it and keep building from there.

I'm injured or just had surgery.

You need to be cleared to train by your doctor or physio first. Once you are, book a call — feeling weak or limited is exactly where I come in.

What if I travel or have a crazy week?

Your program adapts — hotel gym, bodyweight, fewer sessions. Life happens; we plan around it.

What happens on the free call?

You tell me your goals and what's holding you back. I tell you honestly if I can help. If I can, we set up a second call to go through how I'd work with you. If not, I'll point you to someone who can. No pitch, no pressure.

What happens after 12 weeks?

Keep going with a new program — your spot stays yours — or take what you've learned and carry on your own.
