More HRM training

Have been quiet at work today so lots of reading! I had a look at more of my PT sessions and the Zones. They vary quite alot - Saturday's session I spent most of the time in Zones 2 and 4, with a fair bit in 3. Saturday was sprints and weights - pretty much the same as what I did today - except that Rusty was training with me on Saturday. I think the difference is that there was less rest (ie. none!) in between sets on Saturday. All these numbers have me fascinated now! I'm going to keep monitoring and recording everything - just like my own little science experiment :)
