People talk about having to get a single floor home at the age of 70-something or 80-something. If you aren’t doing any strengthening, you are actively training to be incapable of ascending a flight of stairs. Just buy the single floor home now.
If you aren’t training to get better, you are training to get worse. People all the time tell me, “my knee NEVER bothered me BEFORE; it’s a MYSTERY why it bothers me NOW.” No mystery. Entropy. But the human body is an open system and you can add energy to it to improve things if you like. Instead, you’ve been training to get worse. Surprise! You achieved your goal.
Exercise isn’t about stupid f*&$ing calories. It’s about being capable enough to not be an invalid with basic daily life. If you are 30-something, 40-something, 50-something and you aren’t making any effort to ensure your muscles can EASILY take you up a flight of stairs today, then don’t be surprised when they can’t get you up a single step one day soon.
If you aren’t making an effort to at least maintain strength, let us stop with pretense: you are actively trying to become handicapped. That dice roll may land you in a wheelchair next year or in 40 years. But it’s coming.
It’s no mystery. You can cultivate basic fundamental human physical capacity with a couple of minutes of grownup intent. But, if you refuse, then just save your family and friends the heartache and buy the single floor home now.
