There are a few things that you must consider when you are exercising while following intermittent fasting
Type of exercise: If you are exercising in the eating window you may perform any kind of workout. But when it comes to exercising in a fasted state look for light activities like running, walking, yoga or light pilates.
Timing of the exercise: You can exercise in a fasted state, but if wish to perform any stern activity it is always better to schedule them after your meals. The best time is to exercise in the morning, right before having your meal. If exercising during periods of eating, it is important to consider what to eat. Pre-workout nutrition should consist of a meal 2–3 hours before exercise and should be rich in complex carbohydrates, such as whole-grain cereal and protein.
