How old do you have to be when you start and in what kind of health to get that 10%.
The benefits start immediately.
It only takes about 5 years to give somebody, starting at 65, to return them to having the performace they did at 25 years of age if that 25 year old didn’t exercise.
RE: the mice were studied after two months of progressive weighted wheel running....
First we are asked:
Are you a man or are you a mouse?
Why ask the question?
Just do it, as far as you are able. It will have benefits for the heart, lungs and muscles, as opposed to sitting around like a bump on a log.
II believe it’s never too late. Just do it.
I’m 85, in perfect health. My doc felt muscle in my upper arm and said, “You’re very strong, you’ll live to be 100.” That was 10 years ago, and I still have zero health problems except I need a new corneal transplant because of problems caused by stupid doctors.
So, as I said, just do it. Go to the gym, lift weights. Or buy some weights and lift them at home. Gradually increase the weight. I can lift twice as much as I could 10 years ago. And now that the gym is open again, I’m going to increase it to 3x as much. Gradually. Every other day couldn’t hurt.
You will immediately feel better (feel better, sleep better, look better, more energy, better attitude, etc., etc., etc.)
