4Wto1M - Week 2 Day 4

Even though the program says to do each level 3 times a week, I'm doing day 4 of week 2 instead of going to week 3.
Still doing 90 sec / 90 sec intervals 4 times.

I was a little late this morning so I skipped a little of the 5 minute warm up and cut the 5 min cool down to 2 minutes and didn't do the stretching.

Ouch. Paid for it this evening. Stiff and sore.
