The doctor said it is critical for me to do aerobic exercise 30 min. 7 days a week. I did exercise regularly when I had appointments with a trainer. At that time, I was working on looking & feeling good because I was soon going to celebrate my 50th birthday. After my birthday, I totally lost the motivation to exercise. I am now 54 years old. I don't work & have more then enough time on my hands yet I have a hard time getting out of the house to go to the YMCA & work out.. Any suggestions?
