My oldest son came home with a P90X Yoga DVD during winter break freshman year. His pitching coach had all the pitchers doing it. A quick google search gave me this: https://archive.org/details/p90x_20200810
I was interested, so I did it as well. I enjoyed it. Probably not a bad idea for me to get back into it. ;-) Thanks for the reminder @DroppedStrikeThree.
