Yes, you can exercise while fasting during Ramadan, but it's important to do so safely. Light to moderate exercises, like walking or stretching, are usually recommended during fasting hours. High-intensity workouts should be avoided during these times as they can lead to dehydration and fatigue. It’s best to schedule more intense workouts after iftar when you can replenish lost fluids and energy. Always listen to your body, and if you feel too tired or unwell, consider resting instead of exercising.
