I'm somewhat weak physically, what should I do?

I have always been somewhat physically weak. As I get older, I become increasingly lethargic. I sleep a lot and feel sluggish, but fortunately, I haven't had any major health issues. However, because my basic stamina is poor, I come home from work and can't do anything; I just collapse. If I lie down and use my phone, it becomes bedtime...

You need a certain level of basic physical fitness to start exercising or pursue hobbies, but since I lack stamina, my days just end after work. When I get home, I feel like any time after 6 o'clock is just wasted time.

I'm currently taking supplements. I also take Esther Glu, which is well-known. Are there any other supplements you would recommend? Things that are good for health.
