Diet and exercise are both really hard, if not impossible without some kind words letting you know the pain is worth it! I know us PTers are good at support I got myself a bike and have been either riding or walking at least 30 minutes a day (above the walking I do at work which obviously isnt enough lol). This is the second week of this and even though I am sore I do notice that I am feeling stronger and I dont feel as spent after I am done riding.
