I think going out for a trip and boating will be a little more tiring than climbing a mountain, because climbing a mountain can balance the pressure of the body with hands and feet, while boating depends entirely on the strength of the arm, and sitting on the boat doesn't need stretching at all, so it will be more tiring. Climbing a mountain can relieve physical fatigue by resting halfway or doing some stretching exercises, while manual boating relies on the constant movement of arms to speed up the boat's progress, so the limitations of exercise will also make people feel particularly tired. Nowadays, many people especially like some outdoor sports. Relatively speaking, most people will choose some sports with high safety factor to help them exercise and cultivate their hobbies. Mountain climbing is a particularly good form of exercise. Climbing a mountain also gives you the feeling of conquering a mountain, so it is a sport that makes people feel particularly satisfied. Climbing a mountain pays attention to the adjustment of breath and continuous motivation, not speed but endurance. Do more stretching exercises to stretch your bones and muscles before climbing the mountain, so that your leg muscles will not feel particularly sore. Older middle-aged friends, on the other hand, prefer rowing by hand as their daily exercise. Not only do they like the feeling of being on the water, but they also like calmer sports. The feeling of being on the water is like being in a particularly comfortable environment, which keeps you away from the noise and fatigue at work, relaxes people's mood and releases people's pressure. However, in my opinion, the safety factor of rowing is still relatively slightly larger, and the physical requirements are particularly great. First of all, the arms should be particularly strong. Secondly, if you want to row a boat, you should strengthen the movement and exercise of your arms at ordinary times, otherwise you will soon feel particularly tired. Moreover, there is relatively no scope of activities on board, and there is no way to rest and find other foreign aid. Climbing a mountain can rest halfway or let others help you with your things or help you finish this activity.
Therefore, if it is not a particularly steep mountain with a high safety factor, it is still relatively safe, and you can also exercise your whole body. So even if you exercise for a long time, you won't feel particularly tired. On the contrary, everyone will not remember the physical fatigue during the journey. But generally only two or four people row, and they all rely on the strength of the upper body to exercise, which will make people feel that their arms are particularly sour. Therefore, it is most appropriate to choose the exercise that suits you best according to your personal situation, otherwise the exercise that is not suitable for you will bring great influence and harm to your body.
