Please don't beat yourself up! Let me tell you what my doctor's office says. They don't encourage "exercise", they encourage "physical activity". They define physical activity as what you would do above and beyond your normal daily activity. In other words, if you are a construction worker, you can't count that activity because that activity is already included in your every day life. BUT if you added 60-90 minute walks 4-5 times per week above and beyond what you used to do, then THAT IS physical activity that counts! I walk 30 minutes 6 days per week. THAT counts!! I never did that before so it counts!
Let me tell you, I lost 100 pounds in 2007 on a medically supervised diet and a TON of exercise. But that level of exercise was NOT sustainable.
I am committed to doing a level of physical activity that I can sustain for life. Maybe one day I will up my level to be as high as your level, if I feel that it fits into my life.
I want to encourage you to get back up and get walking!!! You are doing great!!! Keep up the great work!!
