The idea behind five minutes everyday came to me from my experience weight lifting and sprint triathlon training. Getting geared up for an hour for every training was a bit of a hurdle so I though since I had a weight bench in the basement even if I only do five minutes it was better then nothing. The barrier to starting dropped. Plus, as often as not I would end up doing a full 30-60 minute work out. As long as I kept in mind the five minute start it seemed to work great. The key I am working with is to keep that five minute start in mind so I don’t feel like I have to do 30 minutes.
