It is best to lose weight and climb mountains. I tried. I lost 30 pounds in Yunnan in a month. Climbing a mountain is actually a long way. It's better to be the kind with slow fluctuations. A little longer. Losing weight is the best. You need knees to go down the mountain. The damage to the knee is the biggest. It would be best if we could go down the mountain by car. Climbing mountains for a long time is very physical exercise. Going downhill for a long time is a torture. It's best not to carry too much weight. Carrying a mountaineering bag with 30-40 kg is ok to climb the mountain twice at a time. Too many times, your back will be too much.
