Mountaineering and ski-mountaineering training plan
phase.fitness plans an expedition or a ski-mountaineering season the way its mountaineering document prescribes: base with unloaded hikes, a build where vertical gain and pack weight rise on a schedule, a peak that simulates summit pushes, and two strength sessions built for carrying load uphill.

The short answer
A mountaineering plan in phase.fitness runs base (8–12 weeks: aerobic base with unloaded hikes and easy runs, high frequency and moderate duration, strength introduced), build (4–8 weeks: vertical ascent sessions of 45–60 minutes targeting 400–800 m, weighted rucks at 20–25% bodyweight progressed by 2 kg every two weeks, altitude intervals of 6 × 3 minutes, strength volume reduced) and peak (2–4 weeks: 45-minute continuous uphill summit-push simulations at zone 3–4). Strength is 2 sessions a week: goblet squat 3 × 10, Romanian deadlift 3 × 8, step-ups with a pack 3 × 12 per leg, single-leg calf raises, dead hangs and trunk holds.
Vertical gain and pack weight are the two loads
The mountaineering document phase.fitness reads names five sessions and orders them across a season: approach hikes of 60–120 minutes with a loaded pack, vertical-ascent sessions targeting 400–800 m of gain, weighted rucks at 20–25% of bodyweight, altitude intervals of 6 × 3 minutes steep at zone 3–4, and summit-push simulations of 45 continuous uphill minutes. Two things progress on a schedule — the vertical metres and the pack weight, by 2 kg every two weeks — and the most common error the document names is starting too heavy: carry 5–8 kg first.
Strength for this sport is load-bearing leg endurance rather than maximal force: goblet squats, step-ups with the pack, single-leg calf raises for push-off and ankle stability, dead hangs for technical grip, trunk holds for stability under load. Two sessions a week in base, reduced in the build as the mountain takes over.
How do you train for altitude if you live at sea level?
You train what is trainable at home, which is what phase.fitness plans: vertical ascent sessions of 45–60 minutes targeting 400–800 metres, steep intervals of 6 × 3 minutes at zone three to four, and weighted rucks. Acclimatisation is not trainable from here — the rotations on the mountain do that.
How long does it take to get fit for a big climb?
Fourteen to twenty-four weeks in phase.fitness: eight to twelve of aerobic base with unloaded hikes and easy runs, four to eight of build with vertical gain and weighted rucks, and two to four of peak, where a 45-minute continuous uphill effort at zone three to four simulates the summit push.
What phase.fitness builds
A program is a sequence of phases, each with a job. These are the phases phase.fitness writes for this case, with the bands the generator has to respect — transcribed from the document it reads, not invented for this page.

| Phase | Weeks | Job | Band |
|---|---|---|---|
| Base | 8–12 | Aerobic base: unloaded hikes, easy runs; strength introduced | High frequency, moderate duration, Z1–2; strength 2×/week (goblet squat 3 × 10, RDL 3 × 8, step-up 3 × 12/leg, calf 3 × 15/leg, hangs 3 × 30 s, core 3 × 30–60 s) |
| Build | 4–8 | Vertical gain and weighted rucks; threshold sessions | Vertical ascent 45–60 min for 400–800 m; rucks at 20–25% BW, +2 kg every 2 weeks; altitude intervals 6 × 3 min Z3–4, 2 min recovery; strength volume reduced |
| Peak | 2–4 | Simulate expedition conditions | Summit-push simulation: 45 min continuous uphill Z3–4, no stopping; altitude exposure if possible |
| Expedition | on the mountain | Acclimatisation rotations are the periodization | Above 3000 m, reduce intensity 20–30% per 1000 m gained |
A sample week
One week from the first phase, as it would sit on the calendar. Your own week follows the days you say you have — 5–6 here — and the equipment you list.
- SStrength
- CCardio
- Rest
| Day | Modality | Session |
|---|---|---|
| Mon | Rest | — |
| Tue | C | Vertical ascent 50 min, 500 m gain, Z2–3 |
| Wed | S | Goblet squat, RDL, step-up with pack, calf raise, hangs, plank |
| Thu | C | Easy run or bike 45 min, Z1–2 |
| Fri | C | Altitude intervals: 6 × 3 min steep at Z3–4, 2 min flat-walk recovery |
| Sat | C | Approach hike 90–120 min with a 12–15 kg pack, real hills |
| Sun | S | Second gym day, lighter; or an easy hike |
S = strength · C = cardio · K = calisthenics. The order is the point: hard days are kept apart and the long session gets the clean slot.
How it adapts when a phase ends
Between phases phase.fitness reads the hikes and runs from Garmin or Intervals.icu — duration, elevation gain, heart rate at the effort — and the strength log. Garmin activities are read only if you allow it. The pack weight is the one load that lives in your notes and the session titles; if the rucks were skipped, the next phase does not add the next 2 kg, and if the vertical sessions came in under the metre target, the peak's summit simulations are sized to what you have actually climbed.
Where the sessions go
phase.fitness plans; you train in the app or on the watch you already use, and the completed session comes back. For this program:
What phase.fitness does not do here
phase.fitness cannot plan altitude exposure or acclimatisation; the document says the rotations on the mountain are the periodization there, and the phase.fitness calendar stops at the trailhead. Hiking reaches a Garmin watch by name; mountaineering arrives as generic cardio.

Frequently asked questions
How does the plan progress the pack weight?
As the mountaineering document prescribes: begin at 5–8 kg, progress weighted rucks by 2 kg every two weeks toward 20–25% of bodyweight, and carry 10–20 kg on approach hikes. phase.fitness writes the target in each session; you log what you carried.
Does this work for ski mountaineering?
Yes. The same document phase.fitness reads covers alpine skiing with an 8–12 week pre-season: foundation with squat mechanics and zone 2 work, a strength phase with heavy squats at 4 × 5 at 80% and lateral plyometrics, then power and ski-specific work such as wall sits and slalom hops.
What if I have no mountains nearby?
Vertical-ascent sessions are written by duration and target gain, and the document names a stairmaster, stadium stairs or a steep hillside as substitutes. phase.fitness pushes the session to your watch either way.
The only app that plans strength, cardio and calisthenics together
For a mountaineer the calisthenics day is grip and trunk under fatigue — hangs, L-sit and hollow holds, pistol-squat steps — the qualities that keep a loaded body organised on the descent.
Right now, phase.fitness is the only training app that writes strength, cardio and calisthenics into one periodized program — same calendar, same phases, same recovery budget.
You choose the mix. A calisthenics-only plan, a cardio-only block, strength plus cardio, or all three: the phases, the end-of-phase analysis and the sync work the same way with one modality or three.
Why calisthenics is in the plan
Bodyweight skill work is strength training in a different shape. Straight-arm work, levers and handstands build scapular control, tendon capacity and relative strength that barbell and machine work leave untouched, and they transfer because they are closed-chain, whole-body patterns. Treated as a modality rather than a warm-up, they get sets, holds and progressions like a squat does.
No exercise catalogue on the market contains a tuck front lever, so those sessions run in the phase.fitness built-in player; strength goes to Hevy, Liftosaur or a Garmin watch, cardio to Garmin and Intervals.icu. How the skill work is programmed.
Free to start, no card. The first phase is yours to keep whatever you decide.
