Compared to just sitting around, playing Minecraft, and jerking off any kind of exercise is fantastic.
Are stair climbers and treadmills the best? Not really; hiking is the best. How long can someone realistically use a stair climber? How long will they use an inclined (but never declined) treadmill before they get bored and go home? Can they stay in high zone 2 or low zone 3 long enough to really build endurance for a long hike?
On the other hand, hiking for health (or prepping for a much longer hike) isn’t really time efficient. How long can someone hike after work?
A mix of everything is probably the best route. Use cardio equipment for more intense cardio, hike on weekends (and maybe once during the week) with a pack for improved endurance, and use strength training for improved muscle recovery.
