How should I train for Mt. Rinjani?

Training for Mount Rinjani doesn’t require a gym membership, expensive equipment, or complex programming. But it does require consistency and specificity. The trek demands cardiovascular endurance, leg strength, and mental toughness, and the best way to build those is to simulate what you’ll actually do on the mountain. Walk uphill. A lot. If you have access to hills or stairs, use them. If you don’t, a treadmill on incline works fine. Aim for at least three to four sessions per week in the month leading up to your trek.

Focus your training on three areas. First, sustained uphill walking for forty-five minutes to an hour. This builds the cardiovascular base you’ll need for the long climbing days. Second, downhill walking or stair descents. This is the one people skip, and it’s the one that destroys knees on Rinjani. Your quadriceps need to be conditioned for eccentric loading. Third, core and ankle stability. Uneven volcanic terrain challenges your balance constantly.

Simple exercises like single-leg balances, calf raises, and planks make a real difference when you’re picking your way across loose scree in darkness. If you have access to actual hiking trails, do some practice hikes with a loaded day pack. Not a heavy pack, just five to eight kilograms, enough to simulate what you’ll carry on Rinjani. Practice walking in the boots you’ll use on the trek, not your running shoes. Break them in thoroughly. Blisters from new boots are one of the most preventable ways to ruin your Rinjani experience.
