If you've been following along with REP's Start Strong challenge, we've been pushing you to level-up your new year's resolutions this year—to climb your metaphorical mountain.

Or... you could be like James Jackson, the face behind the popular Wandering Weights Instagram account, and climb an actual mountain. Mt. Kilimanjaro to be exact. We're not saying you have to shoot that high (although if you wanted to, you can get more info @wandering.weights), but we think climbing a mountain all the way to the tippy top is a pretty epic goal for this year.

So to take this from dream to reality, we chatted with Jackson to get his advice, create a training plan, and get you mountain-ready.

Get Your Mind Right

It's only natural that conquering a mountain brings on feelings of uncertainty, unease, and even self-doubt. Jackson says it's all about perspective — and how you choose to face that internal voice that might be sidelining you.

"I don't think you ever really get over those kind of fears. You just kind of get a little bit more used to it," he says. "I think the biggest advice that I could give is, [your fear] is all just built up in your mind. You're picturing the worst outcome—but what about the best outcome? Chances are it's going to turn out better than you could ever imagine."

Ultimately, fear is a natural part of any challenge, especially when standing on the edge of a mountain. Instead of trying to elimate the fear, face it with perspective and trust in your own abilitites. Over time, those moments of uncertainty transform into confidence, proving that the climb is as much about mastering the mind as it is about conquering the mountain itself.

Train Your Body

The best way to prepare for a big climb is to, well... prepare. Jackson recommends a mix of strength and conditioning with a focus on cardio.

"I think running is the best way to train for hiking," he says. "I'm still lifting, but I'm shifting my focus to prioritize the cardiovascular element."

Below is a training plan created by Jackson to get you in climbing shape. Follow the format increasing load, volume, or intensity each week for 12 weeks. If 4 days a week isn't enough training, you can always add more, but be sure to give your body enough time to recover.

  • Day 1: Push Day (chest/shoulders)
    • Flat bench: 5 sets of 6-8 reps
    • Incline dumbbell flies: 3 sets of 12-15 reps, 90 seconds of rest between sets
    • Dumbbell shoulder press: 3 sets of 6-8 reps
    • L-hangs: 3 sets for 30 seconds
    • Push-ups: 3 sets for 30 seconds
    • Stair climber, run, or hike: 30 minutes

  • Day 2: Pull Day (Back/biceps)
    • Pull-ups: 4 sets of 10-12
    • L-hangs: 4 sets for 30 seconds
    • Barbell rows: 4 sets of 8-10 reps
    • Barbell curls: 4 sets of 8-10 reps
    • Stair climber or run: 30 minutes, increasing speed every 5 minutes

  • Day 3: Legs
    • Barbell back squats: 4 sets of 6-8 reps
    • Dumbbell forward-reverse lunges: 4 sets of 10 reps (5 per side)
    • L-hangs: 3 sets for 30 seconds
    • Stair climber, run, or hike: 30 minutes

  • Day 4: Active recovery
    • Walk or light jog

What Gear Do You Need?

As someone who works out on the go and in the world's most remote and wild places, you'll be happy to hear that equipment is minimal. Here's what he recommends:

Elevation Training

An athlete runs in a weighted vest on a mountain top for elevation training.

Have you ever gone on a stroll at elevation and thought, "Wow, it's beautiful up here. And also, wow, I am struggling!" Oxygen levels are reduced at higher altitudes, making breathing more difficult and causing fatigue to set in faster. 

Training in thin air found at elevation forces your cardiovascular system to work more efficiently, improving endurance and oxygen utilization over time. While this kind of preparation is ideal, it's also a reality that not everyone has access to tall peaks or high-altitude environments. If you're not able train in thin air, Jackson says just hammer that cardio.

"Just run a ton and go on the stairs," he says. "Do whatever you have to do. Just challenge yourself enough to simulate that type of environment where it's hard to breathe."

Takeaway

At this point, we hope you feel adequately prepared to find your mountain and get after it. And if you're having second thoughts, Jackson says this: "If you wait for the perfect time, you're gonna wait the rest of your life. You're not going to get to the end of your life wishing you had fewer crazy stories." Amen to that.
