How to Prepare for a Trek: an 8-Week Fitness Plan (Himalayan and Sahyadri Treks)

Most people who struggle on a trek are not short of willpower. Their legs give out on the third straight hour of climbing, their knees complain on the way down, or they arrive at camp too tired to eat. All three are trainable. This guide explains how to prepare for a trek in India, whether it's a weekend fort climb in the Sahyadris or a week-long Himalayan trek, with the fitness tests operators actually set, an 8-week plan and the altitude facts every trekker should know before going high.

How fit do you need to be for a trek? The tests operators set

There is no single national standard, so each trek operator publishes its own fitness requirement, usually a timed run. The figures below come from operators' own pages. They vary by operator and by trek, so treat them as a guide and check the requirement on the page of the exact trek you book.

Two things stand out. First, the bar rises fast with difficulty: Bikat's eligibility page (last updated in 2015, and described there as "tentative thumb rules") moves from 3 km in 30 minutes for easy treks to 5 km in 25–30 minutes for moderate-plus and harder grades. Second, a run is only a proxy. What the test is really checking is whether you can keep your heart rate under control for hours of uphill walking. That's why the plan below builds endurance first and speed second.

What a trek asks of your body

Preparing physically for a trek means training four qualities, because a trek tests all four on the same day:

• Aerobic endurance: walking uphill for 4 to 7 hours, often for several days in a row.
• Leg strength: every step up is a single-leg step-up with your body weight plus a pack.
• Eccentric strength for descents: going downhill, your thighs work as brakes. This is what makes knees and quads sore on day two.
• Core and balance: a pack shifts your centre of gravity, and loose scree, wet rock and snow punish a wobbly trunk.

The 2024 Adult Compendium of Physical Activities, the standard research table of energy costs, shows how hard this work is. Hiking with a daypack is rated 7.8 METs (multiples of resting energy use), climbing hills at a 5–10% grade with a 10–20 lb (about 4.5–9 kg) load is 6.5 METs, and general stair climbing is 6.8 METs. Walking on the flat at a moderate pace is only 3.8 METs. In other words, a day on the trail is roughly twice as demanding as a flat walk, for far longer. Your training has to close that gap.

Build your cardio base

Cardio is the foundation of any trek preparation. The aim is to go longer before you go faster. Run, run-walk, cycle or walk briskly three times a week, with one longer session at the weekend. Most sessions should be at a conversational pace, where you can speak in full sentences. Once a week, add hills or a few faster intervals to push your benchmark time down.

If running hurts your knees or you're starting from zero, brisk walking on an incline and cycling both count. Bikat's own criteria accept a continuous 8 km or 10 km walk as an alternative for its moderate grades. Our guide to walking for weight loss has a step-count progression that works as a base-building block, and cycling for weight loss covers low-impact cardio on a bike.

Trekking preparation exercises: legs, core and stairs

Strength training is the part most trekkers skip, and it's the part that saves your knees on the descent. Do two sessions a week, on non-consecutive days, at home or in a gym. Three sets of 8 to 12 reps per exercise, with the last two reps of each set feeling hard while your form stays clean.

1. 1

   Step-ups

   Onto a sturdy step or bench at knee height. Drive through the front heel and lower slowly on the way down. This is the single most trek-specific exercise. Add a backpack or dumbbells as you get stronger.

2. 2

   Reverse lunges or split squats

   Build single-leg strength and balance. Take 3 seconds to lower: the slow lowering trains your thighs for descents.

3. 3

   Squats or goblet squats

   Bodyweight first, then a dumbbell or a loaded backpack held at your chest.

4. 4

   Romanian deadlifts or hip hinges

   Strengthen your hamstrings and lower back for carrying a pack. Use dumbbells or a loaded bag, keeping your back flat.

5. 5

   Calf raises

   On the edge of a step, lowering slowly. Calves carry you up every switchback.

6. 6

   Plank and side plank

   Build up to 45–60 seconds each. A strong trunk keeps a pack from pulling you off balance.

7. 7

   Dead bug or bird dog

   Slow, controlled core work that protects your lower back under load.

Stair training is the closest thing to a trail for most city dwellers. Use your building's staircase or a stadium. Start with 10 minutes of steady climbing and walk down slowly, then build to 30–45 minutes, then do it with a loaded pack. Bikat's criteria for challenging grades include three sets of climbing 30–40 steps in one stretch; aim well beyond that by week 6.

Loaded-pack hikes: train with what you'll carry

Your last four weeks should include one long walk or hike each weekend carrying the pack you'll actually use. Start with about half your expected trek load and build to the full weight. If you're using a porter or mule on a Himalayan trek, train with the daypack you'll carry each day; if you're carrying everything, train with that load. This is also when you find out which shoes rub, which straps dig in and how much water you really drink.

• Break in your shoes on these hikes. New trekking shoes on day one of a trek are a common cause of blisters.
• Practise descents, not just climbs. If you have no hills, walk down stairs slowly with the pack on.
• Pack the night before and start early, as you will on the trek.

The 8-week trek preparation plan

This plan assumes you can walk briskly for 30 minutes today. If you can't, add two to four weeks of walking first. Rest at least one day a week, and if a week goes badly, repeat it rather than pushing on.

The taper in week 8 matters. You want to arrive at the trailhead rested, not carrying a week of fatigue. If your trek is a short Sahyadri day hike rather than a Himalayan trek, weeks 1 to 5 are usually enough.

How to prepare for a Himalayan trek: altitude and acute mountain sickness

Himalayan treks add a factor no amount of training removes: thin air. The NHS says altitude sickness can occur above about 2,500 metres, with symptoms that usually start 6 to 10 hours after arriving: headache, loss of appetite, nausea, tiredness, dizziness and poor sleep. A summary of the Wilderness Medical Society guidelines in American Family Physician notes that acute mountain sickness (AMS) can occur as low as 2,000 metres.

How common is it? The CDC gives one example: AMS affects about 25% of all visitors sleeping above 2,450 m in Colorado, and the prevalence of altitude illness can approach 30% at the higher elevations of the Everest base camp trek. The protection is in how you ascend, and good Himalayan trek itineraries are built around it:

If you get mild symptoms, tell your trek leader, stop going up and rest at the same altitude; the NHS says symptoms usually improve in 1 to 3 days, and if they don't improve after a day, descend 300 to 1,000 metres. Never ascend with symptoms.

Sahyadri monsoon treks vs winter Himalayan treks

Trekking in India splits into two very different seasons, and your preparation should match the one you're heading into.

Monsoon trekking in the Sahyadris is beautiful and genuinely risky near water. In July 2024, after five people, a woman and four children, were swept away at a waterfall near Bhushi Dam in Lonavala, the Pune district administration imposed prohibitory orders from 2 to 31 July at dams, waterfalls and picnic spots across several tehsils, banning entry into deep water and gatherings of five or more, as Outlook Traveller reported. Orders like these can return in heavy-rain years, so check local notices before you go, stay out of streams in spate and turn back if the trail turns into a waterfall.

For a winter Himalayan trek, add more pack hikes and stair work in weeks 5 to 7, because snow makes every step harder, and practise walking downhill slowly. For a monsoon Sahyadri trek, prioritise single-leg strength, balance work and downhill control. Either way, strength training is what keeps you steady on the descent.

Food, sleep and the last week before you leave

• Eat enough protein while training so your legs recover. Our protein intake calculator gives you a daily number, and protein in Indian food shows where to get it.
• Don't diet hard in the last two weeks. Arriving under-fuelled makes long days harder. If you're also trying to lose weight before the trek, keep the deficit small; our fat loss goal page explains how.
• Sleep at least seven hours in the final week, and travel to the trailhead with a day to spare if you can.
• Pack light. Every extra kilo is felt on every step up.

When a coach helps with trek preparation

A plan tells you what to do; a coach makes sure you do it well and adjusts it when life gets in the way. If you've never done strength training, have a knee that complains on stairs or have a fixed trek date and limited time, live coaching helps. Personal Home Training is ₹899 a session or ₹8,080 for a 4-week plan of 12 sessions, coached live on video in your own space. If you train at a gym, Personal Gym Training is ₹799 a session or ₹7,070 for 12. See all options on our pricing page. If you're coming back from an injury and your doctor or physio has cleared you, Rehab & Recovery coaching rebuilds strength carefully.
