Gym Fit and Trail Fit Are Not the Same Thing

I learned this the hard way. Before my first multi-day backcountry trip, I figured I was in decent shape. I ran regularly, hit the gym a few times a week, could do a reasonable number of pull-ups. I thought I was ready.

I was not ready.

By the end of day one with a 35-pound pack on my back, my shoulders were on fire, my hips were bruised from the hip belt, and my legs felt like they belonged to someone else. My cardio was fine — I wasn’t out of breath. But everything else was screaming. Turns out, being able to run 10K on flat pavement doesn’t prepare you for 15 kilometres of uneven terrain with weight on your back.

Since then, I’ve figured out what actually works for getting trail-ready. None of it is complicated, but it’s different from a typical gym routine.

The Stuff That Actually Matters

Hiking With a Loaded Pack

This is the single most effective thing you can do, and most people skip it. About a month before any serious trip, I start doing day hikes with my pack loaded to trip weight. Even just walking around the neighbourhood with it helps. Your body needs to adapt to carrying that weight — your shoulders, hips, knees, and feet all need time to adjust.

Start with shorter distances and work up. If you can comfortably do a 10-15 kilometre day hike with your full pack, you’re in good shape for most backcountry trips.

Legs, Legs, Legs

Your legs are doing most of the work on the trail, so they need the most attention. The exercises that have helped me the most:

• Step-ups — Find a bench or sturdy box. Step up, step down. Add a pack for extra credit. This mimics the actual movement of hiking uphill better than almost anything else.
• Squats — Nothing fancy. Bodyweight squats, goblet squats, whatever. Just do them consistently.
• Lunges — Walking lunges are great because they work balance and stability along with strength.
• Calf raises — Your calves take a beating on descents. Don’t neglect them.

If you can find a long staircase — a stadium, a parking garage, a tall building — do laps with your pack. It’s boring and it sucks and it works.

Core Strength

Your core is what keeps you stable on uneven terrain, especially with a pack. It’s also what keeps your back from falling apart after a long day. I’m not talking about six-pack abs — I’m talking about functional core strength.

Planks, dead bugs, and bird dogs are my go-to exercises. Nothing glamorous, but they work. I aim for 10-15 minutes of core work 2-3 times a week. That’s enough to make a noticeable difference on the trail.

Cardio (But the Right Kind)

Running is fine for general fitness, but the best cardio for hiking is… hiking. Or at least something that mimics it. Incline treadmill walking with a pack, stair climbing, or cycling with resistance all work well. The goal is sustained effort at a moderate intensity — you should be able to hold a conversation but not sing a song.

Long, slow efforts are more useful than short, intense ones. A 90-minute incline walk will prepare you for the trail better than a 30-minute HIIT session.

Don’t Forget Your Feet

This sounds weird, but your feet need conditioning too. If you’re switching to new boots or shoes, wear them around the house, then on short walks, then on longer hikes. Your feet need to develop calluses in the right places and adapt to the pressure points of your footwear.

I also do ankle mobility exercises — circles, alphabet tracing, single-leg balance work. Rolled ankles are one of the most common trail injuries, and a little preventive work goes a long way.

A Simple Training Plan

Here’s roughly what my training looks like in the month before a big trip:

Week 1-2:

• 2-3 gym sessions (squats, lunges, step-ups, core work)
• 1-2 easy day hikes or long walks with a lightly loaded pack
• Regular cardio (running, cycling, whatever you enjoy)

Week 3-4:

• 2 gym sessions (same exercises, heavier weight or more reps)
• 1 longer day hike with full pack weight
• 1 shorter hike or incline treadmill session
• Core work 2-3 times per week

Final week before the trip:

• Taper down. Easy walks, light stretching, rest. Don’t try to cram in last-minute training — you’ll just show up sore.

This isn’t a scientific program. It’s just what’s worked for me. Adjust based on your fitness level and the difficulty of your trip.

Recovery Matters More Than You Think

On multi-day trips, how you recover each evening determines how you feel the next morning. A few things that help:

• Stretch after hiking. Even 10 minutes of stretching your quads, hamstrings, calves, and hip flexors makes a difference.
• Elevate your legs. Lie down and prop your feet up on your pack or a log for 10-15 minutes. It helps with swelling and circulation.
• Eat and hydrate immediately. Your body needs fuel to repair. Don’t wait until you feel hungry — eat something with protein and carbs as soon as you’re in camp.
• Sleep. This is the most underrated recovery tool. Go to bed early. Your body does its best repair work while you sleep.

The Honest Truth

You don’t need to be an athlete to do backcountry hiking. You need to be reasonably fit, willing to prepare, and honest about your limits. I’ve seen people in incredible gym shape struggle on the trail because they didn’t train specifically for hiking. And I’ve seen people who wouldn’t call themselves “fit” crush multi-day trips because they put in the prep work.

The trail doesn’t care about your bench press or your marathon time. It cares about whether your legs can handle 8 hours of uneven terrain with weight on your back. Train for that, and you’ll be fine.
