For PE1 in the Handstand One course, the mobility exercise is to hold the bar above the head for shoulder flexion while seated cross legged. In addition to holding the bar for 10 seconds, I swing the bar up and down 10 reps then do 10 pulses (holding the bar at max height while trying to pull the bar past maximum). So my routine is 10 rep swing, 10 second hold, 10 rep pulse. Do you think it is a good idea to do these swings and pulses for PE1?
When I took Adult gymnastics classes my coach had us do beam kick drills where we held onto the wall and did leg swing, holds, and pulses for active flexibility. Since these (kick/swing, hold, pulse) drills work for hip flexion and extension I decided to try it for the shoulder drill on PE1. Is there any reason why I shouldn't do these? Do you think swings and pulses would help to achieve shoulder mastery in PE1?
Also I cannot do the PE1 sitting cross legged because I can't keep my back straight and bend over far enough. Is it acceptable to do the exercise on a chair instead?
Here are some videos that show examples of theses beam kick drills:
