Yesterday afternoon, my run was speed intervals on the treadmill. I did 2 min x 9 at 7.2 mph alternating with 90 sec at 3.5mph. With a 5 -min warm-up and cool-down at 3.5 mph. This was definitely starting to push me. At the end of each 2-min interval, I was very happy to slow down. This totaled 3.54 miles in 41:30.
This morning I did Insanity the Asylum vol. 2 XTrainer and Ab Shredder. This combination still kicks my butt! I burned about 326 calories.
