Hello, I have just arrived at this site and was wondering if someone could tell me which workout program I should start with. I have two kids- the youngest one is 1 1/2 years old and I wuold like to lose my very stubborn belly fat that I would like to get rid of. I am very interested in HIIT workouts and would like to know where to begin since I have no background in this form of exercise. Thank you very much. -Elinor
