Here is some info on exercise and human chorionic gonadotrophin (hCG) :

While on the HCG diet, it  can be dangerous if you do choose to do high-intensity workouts such as heavy weights, cardiovascular workouts like running , or circuit training, you have to be aware that there is a possibility that you may pass out or become dehydrated rather quickly. Be sure that you constantly keep an eye on your heart rate and you drink plenty of water.

Walking is great exercise on the HCG diet. Taking a mile or two walk several times a week on the diet is one of the best ways that you can properly be on the HCG diet and exercise safely.
