## Part 1: Mountaineering

Mountaineering (alpine climbing, high-altitude trekking, expedition mountaineering) demands prolonged aerobic endurance, strength endurance under load, and resilience to altitude-induced physiological stress. It uniquely combines the demands of ultra-endurance hiking with intermittent technical demands.

### Physical Demands

- **Aerobic Endurance:** Summit days can last 8–16 hours at moderate to high intensity. A robust aerobic base — Zone 2 capacity — is the single most important physiological asset.
- **Strength Endurance:** Carrying packs of 15–35 kg over technical terrain for many hours demands muscular endurance of the legs, hips, and core.
- **Altitude Acclimatization:** Above 2500m, arterial oxygen saturation drops. Training at altitude or following "live high, train low" protocols prepares the cardiovascular system.
- **Vertical Gain Capacity:** Uphill efficiency — the ability to maintain controlled breathing and movement at steep gradients — is the defining physical skill.

### Key Training Sessions

1. **Approach Hike:** 60–120 min at Zone 1–2, moderate terrain, loaded pack (begin 10 kg, progress to 20 kg). The most sport-specific training available. Use real hills.

2. **Vertical Ascent Training:** 45–60 min prioritizing elevation gain. Target 400–800m vertical per session. Stairmaster, stadium stairs, or steep hillside. HR Zone 2–3.

3. **Weighted Ruck:** Walking/hiking with pack = 20–25% bodyweight. Builds load-specific leg strength endurance. Progress load by 2 kg every 2 weeks.

4. **Altitude Intervals:** 6 × 3 min steep uphill at Zone 3–4, 2 min flat-walk recovery. Simulates the physiological demands of summit pushes.

5. **Summit Push Simulation:** 45 min continuous uphill at Zone 3–4, no stopping. Trains the ability to sustain effort under accumulating fatigue — the defining challenge of high-altitude climbing.

### Strength Training for Mountaineering (2×/week)

| Exercise                   | Sets × Reps | Purpose                         |
|----------------------------|-------------|----------------------------------|
| Goblet Squat               | 3 × 10      | Load-bearing leg endurance       |
| Romanian Deadlift          | 3 × 8       | Hip hinge / posterior chain      |
| Step-Up with Pack          | 3 × 12/leg  | Sport-specific leg strength      |
| Single-Leg Calf Raise      | 3 × 15/leg  | Ankle stability and push-off     |
| Dead Hang / Grip Work      | 3 × 30 s    | Technical climbing grip           |
| Core (Plank, Bird Dog)     | 3 × 30–60 s | Stability under load             |

### Periodization for Mountaineering

- **Base (8–12 weeks):** Build aerobic base with unloaded hikes and easy runs. Introduce strength training. High frequency, moderate duration.
- **Build (4–8 weeks):** Increase vertical gain training, add weighted rucks. Threshold sessions. Reduce strength volume.
- **Peak (2–4 weeks):** Simulate expedition conditions. Long summit pushes. Altitude exposure if possible.
- **Expedition:** Adapt training on the mountain. Acclimatization rotations are your periodization.

### Altitude Considerations

- Acclimatization follows the "climb high, sleep low" principle
- Above 3000m: reduce training intensity 20–30% per 1000m gain
- AMS (acute mountain sickness) symptoms (headache, nausea, fatigue) → stop ascent, descend 300–500m
- Hydration: at altitude, increased respiratory rate doubles fluid loss — target 3–4L/day

## Part 2: Alpine Skiing

Alpine skiing demands explosive leg power, leg endurance, balance, and reactive neuromuscular control. A typical ski day involves 4–6 hours of intermittent high-intensity leg work. Off-season conditioning significantly reduces injury risk and improves on-snow performance.

### Physical Demands

- **Quadriceps Endurance:** Skiing maintains a sustained semi-squat position under high ground reaction forces. Quadriceps fatigue is the primary performance limiter.
- **Explosive Power:** Turn initiation and edge engagement require rapid force production from the legs.
- **Balance and Proprioception:** Reactive ankle and knee stabilization on unpredictable terrain is essential.
- **Cardiovascular Fitness:** Ski runs of 3–8 min at high intensity require substantial aerobic capacity. Heart rate routinely reaches Zone 3–4 during demanding terrain.

### Pre-Season Conditioning Program (8–12 weeks)

**Phase 1 (Weeks 1–4): Foundation**
- Squat mechanics, lunge patterns, single-leg stability
- Zone 2 aerobic work (bike, row, or run) 3–4×/week
- Core stability and hip stability (glute activation)

**Phase 2 (Weeks 5–8): Strength Development**
- Heavy squats (4 × 5 at 80% 1RM), Bulgarian split squats
- Lateral plyometrics (lateral bounds, skater jumps)
- Short aerobic intervals 2×/week

**Phase 3 (Weeks 9–12): Power + Ski Specificity**
- Ski-specific wall sits (2–3 min), slalom hops
- Box jumps, depth jumps
- High-intensity cardio 2×/week (mimicking ski-run HR profile)

### Key On-Snow Training Sessions

1. **Easy Runs:** Zone 1–2, blue terrain. Technical focus. Active recovery between runs.
2. **Continuous Ski:** Ski full runs without stopping on mixed terrain. Builds leg endurance.
3. **High-Intensity Runs:** Hard descents on black terrain. 6 runs with full recovery on the lift.
4. **Carving Drills:** Slalom poles or carved arc focus. Technical refinement under moderate intensity.
5. **Moguls/Off-Piste:** Reactive terrain demands. Absorb and extend, keep upper body quiet.

### Injury Prevention

- **ACL tears** are the most common serious ski injury. Neuromuscular training (landing mechanics, single-leg squat control) reduces risk by 50–70%.
- **Core bracing:** Active core engagement on every turn reduces spinal load.
- **Binding settings:** Calibrate DIN settings annually — too tight and release is inhibited; too loose and pre-release occurs.

### Cardiovascular Conditioning for Alpine Skiing

Alpine skiing is interval-based: 3–8 min of hard effort followed by 5–10 min of chairlift rest. Program cardio to reflect this:
- **4 × 5 min at Zone 3–4, 8 min rest** replicates a hard ski run with a chairlift ride
- Cycle ergometer and step machine are the best dry-land approximations
- Target 3–4 sessions/week of ski-specific cardio in the 6 weeks before the season

## Common Errors

**Mountaineering:**
- Starting too heavy too fast: Carry 5–8 kg first, progress gradually. Injury risk spikes with rushed load progression.
- No vertical training: Flat hikes build endurance but not the specific cardiovascular adaptation to steep grades.

**Alpine Skiing:**
- No pre-season leg work: The single greatest predictor of day-3 ski fatigue is quad strength. Build it off-snow.
- Skiing through fatigue on tired legs: Fatigue causes form breakdown → significantly elevated ACL risk. Stop when quads burn significantly.
