What happened to the for 30 or 40 minutes walks? What she really meant is that she was 30 or 40 minutes off the bed or the couch. A 30-year-old woman who cannot walk more than 300-400 meters at a slow speed cannot consider herself as healthy as other women even much older. Either her joint as hurting too much or her heart is pumping too much or she cannot maintain oxygenation of her tissues with a little exercise. It is interesting that each time she says that she is doing much better than before, in reality, she is doing much worst. She is now as bad as when she was 50-60 pounds heavier. Time is catching to her and she does not even realize it.It's Becky's idea for Amber to walk as far as she can, and compare the distance to her previous record. Amber starts discussing this at 20:05. She says that when she felt "done," she was at .20.
She did keep pushing herself to 0.31. But at a fifth of mile, she was ready to quit.
