# 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

| 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

| Day | Modality | Session |
|---|---|---|
| Mon | Rest | — |
| Tue | Cardio | Vertical ascent 50 min, 500 m gain, Z2–3 |
| Wed | Strength | Goblet squat, RDL, step-up with pack, calf raise, hangs, plank |
| Thu | Cardio | Easy run or bike 45 min, Z1–2 |
| Fri | Cardio | Altitude intervals: 6 × 3 min steep at Z3–4, 2 min flat-walk recovery |
| Sat | Cardio | Approach hike 90–120 min with a 12–15 kg pack, real hills |
| Sun | Strength | Second gym day, lighter; or an easy hike |

## 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

- **Garmin** — Write it here, train it on your Garmin: strength and cardio sessions are sent to Garmin Connect and appear on the watch, and the activities you finish come back to mark the plan done.
- **Strava** — Post to Strava: the sessions you finish in phase.fitness go to your Strava feed, only the ones you choose. Nothing is imported from Strava.
- **Intervals.icu** — Cardio sessions go out with intervals and zones intact; completed sessions, HRV and load come back.
- **Hevy** — Strength routines are written to Hevy; logged workouts return to phase.fitness. Cardio and calisthenics do not travel here.

## 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.
