Last year at this time (actually the day before Thanksgiving) I started my new "lifestyle." Proper exercsie and proper eating (no diet - just PROPER eating).
Prior to the new program I had put some weight on and felt pretty lousy. A trip to the doctor told me (after blood tests) that my lipids were bad, I was diabetic and quite frankly - obese. That did it - new incentives to stay alive.
About a week before I had "winterized" my 16' Carolina Skiff. It just about killed me. I was so exhausted I swore to get rid of the boat. Instead - I swore to get in shape and save my life. After all - my family depends on me.
First thing: I joined a new "bells and whistles" gym. Cost more, but the new atmosphere is better/friendly/nice clientelle and staff and I'd rather spend the money at the gym than for doctor bills. The new atmosphere stimulated me to "show up" to work out. Afterall - the secret to weight workouts (builds muscle to more efficiently burn calories) is just show up at the gym. You WILL work out IF you get there. My wife purchased me a hot-tub. Sure makes me feel better and I use it every day (twice).
Second: got a training partner - Blue Boy. I've talked about him before. He was eight weeks old when he came home with me. He is my walking partner. Blue Boy is an English Cocker Spaniel approaching his first birthday. Little sucker keeps me moving and I walk with him EVERY day. The loyalty he shows me is paid back by taking him out and having fun with him. We are BOTH in better shape due to the time we spend with each other. Blue Boy is laying at my feet as I write this!

third: rowed during the winter (when it's warm I'd rather do "outside stuff"). I rowed quite hard for me and the weight started coming off.
fourth: off-season (warmer months) - I did outside stuff - kayaking, walking, visited the gym (maintenance program) and had fun outside.
So........it's been a year and has it made a difference? Thirty pounds off and I"ve kept it off. Blood tests are normal and my cholesterol was the lowest in years. No more high blood sugar.
I recently winterized my boat - no problems. Better yet - I helped a friend unload a LARGE van full of items he had purchased at auction. I felt invigorated. I go up stairs and hills now without breaking a sweat!!
I retired three years ago. I run into people that haven't seen me in that time and they say I look better now than when they last saw me three years ago - it keeps me going.
I will be 64 years old on January 8 (Elvis and I were born ten years apart). This year I plan to do even better - It's never too late!!
