As expected, the second day was quite hard being still sore from day 1.
I notice that while I can get along with most exercises, some are extremely hard for me without knowing why exactly. I HATE Mountain Climbers for example even though I am ok with planks and other cardio exercises but the combination...30 seconds into the exercise (which should last 1 minute) I am always checking the watch being sure one minute has to be over.
I also don't get better at Pull-ups (chin-ups?). Could do zero a year ago, can still do zero without supporting some of my body weight with my feet.
