After some experimentation, I found that reducing my workout time to 1.5 to 2 hours per day produced the same results as my earlier longer workouts. I think this was because my body had adapted to the workout routine and didn't need as much time to get the same benefits.
For beginners, I would recommend working out for 2 to 3 hours per day, as their bodies may feel pain initially, and they need to gradually build up their strength to lift heavier weights. Over time, as their bodies get used to the workout routine, they can reduce their workout time to 1.45 to 1.5 hours per day, which should be sufficient to maintain their fitness level.
If you have any experience, don't hesitate to comment. I feel happy when I read your comments.
