Oh, Lord. I've done their 'workout' by the time I walk in the door at work every morning. I even use my arms.
Guess that means I don't need the five weights sessions, the rowing, bike or running at the week anymore, never mind the proprioception exercises, barre, swimming, trashing the DP at football, basketball and skipping or the shagging anymore.
Sorted. I shall retire to my sofa and wiggle my toes for some chair yoga instead.
