I get the ride everyday thing. It makes perfect sense. I'm about an hour bike ride away from work and need a shower etc before I throw on the noose and monkey suit. So I find it way too easy to sleep in past the alarm and just catch a train.
So I do a lot of riding on my off days, and then core training at the gym on workdays in the evening.
Check out a personal trainer, they'll set up a nice personalized program for you; even if you only see them once or twice.
But yeah, commuting is ideal.
