I do my in the evening around 5 when I get off work. I would like to do them in the morning but I have to be at work at 7am and with mid night feedings of the baby I need that extra time in the morning to wake up.
It can be hard to workout in the evening. My setup is in my garage and with the heat it can be a real challenge to cool myself even with fans. It can also be hard to have the workout looming over my head.
