Week three goal met

Hurray, week 3 reach my goal again. This week I have increased my indoor walking workouts. I did three days of aerobic walking workouts about 4 minutes at a time. Each day I walked 3 or 4 times to reach 1 mile workout. Biking I did interval training that covered longer aerobic workouts. I usually did my daily fatman body exercises, with a little band workouts. Walking limits because of pain but I feel better than I have. Biking I believe is still key in improving aerobic fitness but I am encouraged about walking.
Can't give up, keep walking
