I was wondering about how everyone defines intensity, especially in terms of Day 1 rounds. In the beginning I would set my countdown timer at 20 minutes and keep an eye on it to gage my pace. I always set out to beat the my previous record at that level. But if I had, for example, 20 rounds previously, I'd mentally prepare myself saying I could pace out a little over 1 round per minute and beat my record. To me that seemed like it wasn't really giving my all. It wasn't easy but there was no reason to limit myself to one round per minute.
I guess what it comes down to is what do you think would be better in completing 20 rounds, like 10 in the first 5 minutes and then 10 over the next 15 minutes or one round per minute? Is there a difference?
