I like how easy it was to use, even if you have no experience with fitness apps or programs this one will be perfect! It's very user friendly so anyone can get started right away without any problems at all. There are many different ways of tracking your progress as well which makes things easier than ever before. Sometimes there could be some lag in using certain features but overall everything seems great about this program. The only thing i dislike would probably be having multiple options when adding exercises into my workout plan. This helps me keep track of what workouts i've done already vs those yet to do.
