Hello Emese,
Great question-so level 0 is to get you used to the movements and how to do them correctly. The Level 1 video will take you step-by-step on each exercise, and it doesn’t follow 6 sets of 10 reps but is focused on movement for a certain amount of time. The entire video is actually a little over an hour, and so, therefore, the workout time in Training Peaks is that long. I hope that answers your question!
