Day 53 is Kenpo for me.
In an effort to really pump up this workout because I feel great today, I add more reps to each series, get really low in all of the horse stance's for the block and elbow series, and try to widen my "step and drag" on those series. Plus double time all the jumping jacks. And it feels gooooood! And because I am slightly annoyed with people, its also extremely satisfying today :)
Oh yes, and the stretch in the beginning that I always have trouble with goes well today! Finally! I have more trouble when I kick the left leg out than the right, but then my left hip is always tighter, so that makes sense.
