I apologize if these questions have been answered before, but I couldn't find the answer anywhere.
1. For the mobility training, the exercises often (but not always) say what the mastery level is for example 10 reps for skiers. Does this mean that one must always do 10 reps or must you use the mastery tables and work your way up.
2. The guide says that for warm-ups you should do some of the lower tier exercises. I am at PE1 for all but two exercises, how does one warm-up for PE1?
