Phase 1 was doing all my one-mile walks
Phase 2 was doing the same but adding in extras like weights, stretchy band, and walk belt.
Phase 3 was adding in all the 2-mile stand-alone workouts.
Phase 4: Phase 3, plus if there is a choice between 1 mile or 2 mile on the DVD, I'll do the 2 miles. I have also added in a few DVDs from the library to shake up the pace and motions a bit. They vary between 1-2 miles equivalency. On the DVD that has 5 one-mile workouts, I'll combine two of them at least once.
