Ever heard of Ronald Reagan? He was a Hollywood star who became a U.S. president. He was also a fitness nut. Reagan said there were two keys to exercising:
1. Find something you enjoy.
2. Keep the exercises varied.
Jesus may be the same yesterday, today, and forever, but sameness will always spoil your workouts. Among other things, Reagan used to ride horses. I don't know if you realize it, but so did I. Here's Reagan enjoying a canter on his Thoroughbred.
Here's me on mine.
Furthermore, Reagan's gym in the White House had a treadmill, an exercise bike, and a machine to work his arms and legs. Each day he exercised for about 30 minutes, always alternating his routine.
The point is simple: Do whatever works for you, but make it fun, and keep it varied. Eat when you're hungry. Drink (water) when you're thirsty. Pick your activity (or activities) and do it (or them) 3 or 4 times a week. And please, don't forget to exercise your brain. When I lived in California and took the daily LA Times, I used to do their crossword puzzles. Nowadays I read, study, and write at least 2 hours a day. My home is a gymnasium for the mind.
I turn 70 this June. I once read that the health-adjusted life expectancy (HALE) for Americans is only 70 years, which doesn't even make the global top twenty. The HALE, by the way, refers to the length, not of one's life, but of one's healthy, active life, in contrast to the total number of years we spend on this earth.
If you don't want to take it from me, take it from Ronald Reagan. Find something you enjoy, and keep the exercises varied.
Good health to you all!
