A great thing about Grokker is that you can watch videos at any time! The platform was built with anytime-access in mind, so if you do want to repeat an excercise multiple times you can always rewind it or rewatch the video. You have the ability to personalize your work outs to your own fitness level. For programs, when you sign up they give you a structured workout schedule, but you can always take extra time if you need to. You can do this!
