How often do you climb? For people who have no sports foundation, it should be at least two or three days apart, and it takes a week for people with poor health to recover their physical strength. The common exercise frequency can be once a week or once every other week.
There is a concept in sports training called "excessive recovery", which means that in order to improve human function, it is necessary to exercise with a little load.
If you can't climb the mountain every week, do other aerobic exercise at least every two or three days. For example, the stair trainer and stair climber in the gym can exercise thighs and buttocks. The easiest thing is to climb the stairs and keep exercising, and then you will feel relaxed when you go hiking.
