Why Couldn't I Do 50-minutes?

Today, I started a high intensity cardio workout that was 50-minutes long. Lots of jumps, jacks, etc. I've done it before to completion, although it was challenging. Today, I got to 22-minutes, and knew I was "done in," so went to the cool down. I was exhausted. Could it have anything to do with the heavy weight lifting day I did yesterday? It was only upper body, but it was intense and an hour long. Would that really have an effect on my energy level today?

What do you think?

I agree with what someone else said, likely factors to do with sleep and how you are feeling overall. I think you do fantastic with all you keep up with:)

Exercise keeps me going, Raven. Yes, it's probably a combination of factors. @ravenwind43

@Carissimi I feel so much better exercising I know that.

@ravenwind43 Me too. If I don't exercise my joints stiffen after a few days. I always say that it's exercise that keeps me standing, and able to lug grocery bags up several flights of stairs without getting winded.
