It's Always the Last Set

It's always on the last set, or on the "last run down the hill".

Doing the VO2Max 16kg 15:15 of 46 sets of 8 Reps on my last set I tore a callus on the inside knuckle of my left middle finger. Argh! Anyways, tomorrow is a scheduled day off with CK-FMS screen at night.

I checked my pulse after the last set and it was 148. That seems a little low, but maybe my recovery is fast ?
