Successful **Kilimanjaro training** requires a **12-week endurance and conditioning program**. Climbers should focus on cardiovascular training (running, swimming, cycling 3-4 times per week), strength conditioning for core and legs, and specific training like walking on stairs or hiking steep trails with a weighted daypack (6–10 kg).
You cannot fully train for altitude at sea level, but being physically fit reduces your body's oxygen consumption rate. On the trail, the key to acclimatization is walking slowly ("Pole Pole" in Swahili) and drinking at least 4-5 liters of water daily.
