In addition to my daily walks, I've started an exercise program that incorporates some exercises recommended in a recent issue of the AARP newsletter...stretching, body weight squats, touch your toes, etc. I'm combining that with a couple of exercises recommended by my scuba diving insurance company that are designed to improve upper body strength. I use two 20 lb hexagonal dumbells. The two exercises are pullups and pushups both done from a bent-knee position in the deck. Then I add some overhead lifts with the dumbbell one arm at a time, and some curls. I'm hoping that the body weight squats help improve the muscle tone in my left leg, which is somewhat atrophied due to a long ago bout of sciatica and arthritis in the knee. I'm trying real hard to stick to my low carb diet. My weight is good at about 190, down slightly from where I've been in recent months after my surgery. I stopped Warfarin last Tuesday with the blessing of my cardiologist so now the only pill is a daily aspirin. That made me happy. I have my first post op echo in a couple of weeks, but the valve seems really good. I have no palpitations or other symptoms and it really pounds shut. I know it's working, that's for sure! Finally, Monday I start cardiac rehab. I'm getting a late start due to the move to the summer cottage but I at least want to try some sessions to see if they are helpful.
