Training for Mount Rainier (and Beyond): How to Train Smarter for the Mountains

from gym to glacier: training for rainier and other cascade climbs

What does it really take to feel strong, steady, and capable in the mountains?

In this recorded webinar, Alpine Ascents guide Dom DeMatteo breaks down a practical, individualized approach to training for Mount Rainier and other mountaineering objectives—without disappearing down a rabbit hole of exercise physiology. Instead, Dom focuses on the real demands of climbing in the mountains: long days, heavy packs, variable terrain, and altitude. The kind of challenges that can humble even very fit athletes. Rather than asking you to overhaul your life or follow a rigid, one-size-fits-all plan, this session is about translating the fitness you already have into effective on-mountain performance.

What This Webinar Covers – Dom walks through how to:

  • Assess your current athletic background and training history
  • Identify the most common gaps that show up in mountaineering—especially for climbers coming from running, cycling, or gym-based training
  • Build a realistic, sustainable training plan that works alongside a busy schedule
  • Prepare your body for the specific stresses of climbing at altitude, under load, and across long, demanding days
  • The goal isn’t to train harder for the sake of it. It’s to train smarter—with intention, efficiency, and the mountains in mind.

Why Dom’s Perspective Is Different

Before guiding with Alpine Ascents, Dom worked as an exercise physiologist and coach and competed as a high-level endurance athlete. He brings together scientific insight, coaching experience, and real-world mountain knowledge to offer an approach that’s both grounded and practical.

This webinar is especially valuable if you’ve ever thought:

  • “I’m fit… so why does this feel so hard?”
  • “I train a lot, but it doesn’t seem to translate on big climbs.”
  • “I want a plan that actually fits my life.”

Whether you’re preparing for your first Rainier climb or refining your training for bigger objectives, this session offers clear takeaways you can put into practice right away.  Here’s a link to his Training Cheat Sheet that he references during the presentation.
