Rob Shaul of Mountain/Military Athlete fame is also a big proponent of stepups. I recall encountering them in his programming on a routine basis.And that’s the prescription; use weighted step-ups in a progressive pattern when training in mountain environments isn’t an option. I caught wind of this approach from Mark Twight who successfully summited east coast based clients. Given a preference I’m 110% with you!
On another, unrelated, note I like the concepts put out by Mountain Athlete (building a pound for pound stronger, faster mountaineer with a big gas tank) and seeing the potential transfer for yet another weight constrained athlete with a wide mix of requirements...the fighter/combat athlete.
