HNers who train from home using minimal weights or equipments, can you suggest a path for me.

I am looking for some hints on:

1. What is the bare minimum balanced routine I can start with?

2. How long should I stick to it before I see or feel actual results from it?

3. Diet? Eggs are easily available for me.

4. A bit about your journey. How you started and how have you progressed on parameters of strength, routine, size, energy, etc.

P.S: I came across this youtube channel: https://www.youtube.com/@Kboges where he suggests that to gain strength and general fitness you can train daily with 3 movements but not to failure. Is it possible?

My goals are to have enough muscle and strength so that I don't get tired doing chores lifting something for my household. I want this to go far into my old age so that I don't fall and spend my final years in a nursing home bed.
