Best time to train during Ramadan can be 1 hour before breaking your fast.
Generally good for a low intensity workout rather than HIIT or weight training. Your carbohydrate levels will be very low at this time so you won’t have as much energy as you normally would, however it’s a more sociable hour.
Major downside is you can’t drink water during your workout so make sure you get plenty of fluids in the moment you break your fast.
Exercise after your evening meal is reasonable option
It’s never easy exercising on a full stomach but during the fast, after food seems the most logical time to get a routine in.
As you are only exercising two or three times a week, on those days, you may want to eat a little to refuel your body, being sure to drink enough water to re-hydrate yourself and then break your meal to do the exercise.
That way, you will have more energy for the workout, but still have the opportunity to return to the meal.
