Quick answer

If fasted exercise feels good, before can work; if you feel weak, train closer to or after your first meal.

Step by step

01 Test one timing for a week.
02 Track energy and performance.
03 Move training if symptoms appear.

The longer answer

The best timing is the one that supports consistency, performance, and recovery. Track how workouts feel at different points in the window.
