Kat-
I'm midway through week 5, I'm soon to be 54 years old and when I started this training I was 230# and am now 222# and the day before I started A brisk mile walk took me 19 min and I was also out of breath.
I have Never follow through with any kind of exercise ever before until now. It's a challenge I have given myself, (to do a 5K) every day I get out there and do it, I am more surprised that I was able to actually complete the whole 30 minutes. Even as every week adds a little more jogging. The feeling of accomplishment is so motivating for the next day. I also am being motivated by two other gals on this app, we check in with each other every few days. If you would like to join us let me know.
Good luck!!
