Well, I can't recommend anybody try to duplicate my approach. It was a somewhat haphazard, self-designed mishmash that happened to work out okay despite being far from optimal. There are infinitely superior resources available for anybody interested in the subject.
My first introduction came from Danny Dreyer's book Chi Running (McDougall's Born To Run is very good too, but more of a memoir). Despite being a little new-agey in places, I found it to be very helpful. It contains some valuable general concepts, some specific cues and drills as well as a comprehensive beginner's program for developing mid/forefoot strike. However, I lacked the patience to follow that program. I did incorporate the drills into my warm-ups and focused on the cues and concepts ("quiet feet", quick, light, springy foot strike, forward lean, lengthening stride to the rear, pelvic rotation, low, loose, square shoulders, relaxed neck/jaw etc.) during my runs. At that time I was doing all my running (not much and mostly speedwork) in a pair of 5+ year old broken down trail shoes with the soles so badly compressed that they were gradually becoming more and more "minimalist" 1k at a time.
I then got into a program that involved mandatory group runs of 3-5+k with mixed sprints and calisthenics 3+x/wk. I really focused on form during these runs and made respectable (for a non-runner) progress. By the end I ran a timed 2500m (1.5 mi) in under 10 minutes. Nothing special but a big step forward for me. More importantly I felt very comfortable with my stride and had no pain. I feel I could comfortably have pushed significantly more mileage, but I didn't really see the point.
When I got my Minimus I dialed it right back and started at the beginning of "Couch to 5k"
(60sec easy pace running followed by 90sec walking for 20 min). I treated these runs as "practices" as opposed to "workouts" as they were designed for someone starting, well just off the couch. I had to really discipline myself not to turn the "60sec easy pace" into a "60sec 85-90% sprint". I found that after a 3 weeks following the Couch to 5k progression I was good with the Minimus and returned to my regularly scheduled programming.
Like I said though, there are far better ways to do this. People who actually know what the hell they are doing offer clinics all the time.
