finally managed to run 5 minutes straight! I did it on day 4 of week four. jogged, slowly, for both 3 minute intervals and five minutes for the first five minute interval. For the second 5 minute interval, I only lasted 90 seconds before I had to walk for a minute then jog again, walk then jog the last minute.
Day 5 of week 4 was a carbon copy of Day 4. Day 6 I managed to jog about 2 minutes the last interval before having to walk.
Tomorrow I'll be starting the week 4 training for the third straight week.
If I was jogging any slower, I'd be walking. I run on a flat surface and am never sore. I try to breathe in through the nose and take deep breaths, pushing my diaphragm down and exhaling through the mouth.
After repeating week 3, I thought I'd have to repeat week four, but having to repeat it twice is rather discouraging. I'm not even close to jogging 5 minutes twice in one session ,but I'm going to keep at it.
Still accepting advice. Again, I'm never sore; I just get very winded.
