Building Strength and Endurance for Adventurous Activities

I’m always looking for ways to make my workouts more exciting and functional, especially since I love getting outdoors for hiking and climbing. I’ve been doing some basic strength training, but I want to mix it up with routines that really prepare me for unpredictable terrain and longer adventures. What are some unconventional exercises or training methods that have worked for you? I’m curious about anything that builds both power and stamina without feeling like a typical gym session.
