The first thing people ask us when they claim a spot on our Everest Base Camp or Annapurna Circuit group is, "how do I train for this?" It's exactly the right question. The Himalayas don't ask you to be an elite athlete, they ask you to be consistent. A multi-day trek that climbs past 5,000 meters isn't something you improvise, but it doesn't demand a year in the gym either. Here's what to train, when to start, and how to use whatever terrain you have nearby to arrive with your body ready.
In short
You don't need to be an elite athlete. You need aerobic endurance to walk 6 to 8 hours a day, day after day.
The descents, not the climbs, are what punish your knees and quads the most. Train your strength.
Training with a loaded pack is a smart move (start at 3 kg and build up to 8 kg): it changes the whole rhythm of walking.
Altitude isn't something you train for at home, it's something you manage on the ground through gradual acclimatization.
Give yourself at least 12 weeks. Ideally, add a high-altitude trek beforehand as real experience.
What fitness level do you actually need for the Himalayas?
You need the fitness of an active person, not a marathon runner. Everest Base Camp and the Annapurna Circuit aren't for couch potatoes, but they aren't for professional mountaineers either. The profile that works best is someone who walks or runs a few times a week and doesn't fall apart after two hours of continuous effort. The training we recommend isn't about summiting Everest, it's about enjoying the trek without your fitness ever becoming a worry.
The key word is "active." Being active around the city isn't the same as being ready for the Andes or the Himalayas. That's why specific preparation matters: endurance for long efforts, strength to descend without hurting yourself, and a tolerance for altitude that, as you'll see below, you can't fully train for.
Which capacities do you absolutely have to train?
There are three, and it pays to work on them together from day one. None replaces the others, and neglecting one is the most common reason people suffer more than they need to on the trail.
The first is aerobic endurance. Your body has to be able to walk 6 to 8 hours without wearing out, several days in a row. It's not about speed, it's about duration. Running, cycling or the incline treadmill all count: any steady, sustained cardio builds that base. And it's not only about not getting tired, it's about recovering fast enough to do it again the next day.
The second is strength. The Himalayas' long descents hammer your knees and quads if they aren't ready. Squats, leg press and climbing stairs (or a plyo box) with a pack are your best allies. People underestimate the downhill, and that's exactly where most of the aches show up. Core strength matters too: your abs and lower back keep you upright under a pack that, while light because we always porter the group gear, is still an external weight you need to carry comfortably.
The third is getting comfortable with the pack. Carrying 5 to 8 kg for one day is one thing; carrying it for hours every day completely changes your balance and how much energy you burn. Training with weight early prevents back and shoulder issues, and it means the real weight on trekking days never catches you off guard.
What does a week-by-week plan look like with no mountain nearby?
One approach is to split it into three progressive blocks: base, endurance and specific work. The logic is simple: first you build the habit and wake up the muscles, then you stretch the duration, and finally you rehearse something as close to the real trek as possible. You don't need to live near the mountains to pull it off.
| Block | Weeks | Focus | What to do |
|---|---|---|---|
| Aerobic base | 1 to 4 | Habit and easy volume | 3 cardio sessions (30-45 min), a 2-3 h walk on the weekend, leg strength twice a week |
| Endurance | 5 to 8 | Duration and elevation | Longer walks or jogs, seek out stairs, bridges and hills, start carrying a pack (5-8 kg) |
| Specific | 9 to 12 | Simulate the trek | At least one 2-day outing with a full pack and real elevation, keep up the base cardio |
In the base block the goal isn't to exhaust yourself, it's to lock in the routine. In the endurance block you add elevation, which is what most resembles the mountain: with no hills at hand, the stairs of a stadium or a tall building, or the slopes of a park, do the job. And in the specific block you go for the full experience, with a two-day outing carrying a pack and sleeping outdoors, the best dress rehearsal before you travel.

Can you train for altitude from home?
You can train for the mountain, but that's different from acclimatization, and it helps to be clear about it from the start: acclimatization isn't something you build in your city beforehand, it's managed on the ground. You can arrive in flawless shape and still feel the altitude, because each person's response is individual and doesn't depend on training alone.
What you can do is respect the rules of good acclimatization during the trip: climb slowly, hydrate well, eat light and never ignore the symptoms. That's why our Himalaya itineraries already build in gradual ascent days, not as filler.
If you want to understand what happens to your body as you gain altitude, it's worth reading about the phases of acclimatization and how to prevent altitude sickness. Arriving informed is part of the preparation, just as much as your legs are.
How to use Argentina's mountains as a rehearsal?
Use them as a testing ground before you cross the world. One of the best things about preparing from Argentina is that you have accessible mountains to live the experience for real, not just to train in the abstract.
Champaquí (2,790 m) in Córdoba is ideal for testing your endurance and seeing how you handle days with a pack on. Los Gigantes stands out for its uneven, rocky terrain, something a gym treadmill will never give you.
And if you're after real altitude, Cerro del Medio in Mendoza (4,170 m) is the perfect warm-up before the Himalayas. It takes you into high-mountain terrain, you sleep in a refuge, and it shows you how your body responds to altitude before heading to the other side of the world. It's not mandatory, but the people who do it arrive with more confidence and fewer worries about their fitness. To take the first step, an entry-level outing like the Mirador Tolosa ascent is also a great option.
What are the most common preparation mistakes?
The most common one is training with too little lead time. A handful of days before the trip isn't enough for your body to adapt and produce the changes that actually improve your fitness. Start preparing seriously at least 2 months out if you want to do it calmly. You can do it in 30 days, but it'll be far more intense.
Another frequent mistake is training only the climbs and forgetting the descents. In the Himalayas you go down as much as you go up, and it's the downhill that wears out your knees. If you've never trained the eccentric braking of your legs, you'll feel it.
The third mistake is leaving the pack for last. Many people train for months without weight and only load the pack on the trip itself. Your body needs weeks to adapt to walking under load, so add it early and gradually.
The fourth is starting too late or too hard: three weeks out with brutal sessions leads to injuries, not fitness. Consistency beats intensity every time. And the fifth is believing the gym is enough: without real hours of walking, jogging or steady cycling, your legs never learn to last.
How do you know you're ready?
You're ready when you can walk for hours with a pack and finish without your legs giving out, when descents no longer wobble your knees, and when you've done at least one full 3-day trek and enjoyed it. Those three milestones together are the clearest sign.
You need more time if long walks leave you wiped out for days, if you have niggles that keep coming back in your knees or ankles, or if you've never trained with a loaded pack. At MONS we talk with each person before the expedition to gauge their level and, if needed, adjust the plan or suggest a high-altitude outing first. Message us on WhatsApp at +54 9 3512 11-3842 and we'll figure it out together.
Frequently asked questions
How far in advance should I start training for the Himalayas?
We recommend at least 8 weeks if you're already active. If you're coming from little activity, give yourself 3 to 4 months. What matters most isn't the number of months but consistent weekly training sustained all the way to the trip.
Can I prepare if I live in a city with no mountains?
Yes. Aerobic base and strength can be built anywhere with cardio, stairs, urban elevation and long walks with a pack. Ideally, add at least one real 2-3 day outing before you travel to test everything together.
Do I need to do a high-altitude trek before the Himalayas?
It's not mandatory, but it helps enormously. An outing like Cerro del Medio (4,170 m) shows you how your body responds to altitude before the trip. Altitude tolerance is individual, and it's worth knowing yours in advance.
What's the difference between preparing for Everest Base Camp and the Annapurna Circuit?
The physical demand is similar: both ask for long-haul endurance and strength for the descents. The differences lie in the altitude profile and the itinerary logistics. We compare the two routes in detail in this breakdown.
Does MONS support your preparation before the expedition?
Yes. With every traveler who books a spot we do a check-in beforehand to make sure they arrive ready and, if needed, we suggest a training outing. Ask us on WhatsApp at +54 9 3512 11-3842.
If walking in the Himalayas is your dream, the best time to start training is today. The second best is tomorrow. If you've already booked your spot, you have our support to arrive in shape.
