I'm close friends with twins I met in college over 30 years ago.
One twin is married and like to follow the rules.
"Will walking burn the same amount of calories as jogging, if the distance is the same?"
The other twin is the EXACT opposite, likes to go out to bars and stays out until 2:00AM or later and practically lives the life of a rock star.
I'm more like the mellow brother, but about once per month will attempt to stay out as late as the wild one.
I get exhausted just writing about it right now.
The crazy thing is that the one who parties like crazy looks younger than his brother.
He HAS been more consistent with exercise.
There could be other factors involved...
But
An interesting aging study that examined twins, found that a twin who exercised vigorously for at least 3 hours per week had much longer telomeres than an inactive twin who exercised less than 16 minutes per week.
I have mentioned this before.
Scientists believe that aging is caused largely by the shortening of your telomeres.
Exercise is crucial to slow this process down.
Also...
One study found type 2 muscle fiber training is crucial if you want to stay lean as you get older.
This research examined what happened when they genetically engineered mice to acquire more type 2 muscle fibers.
They found when type 2 muscle fibers were increased the mice were able to get ultra lean like an Olympic sprinter.
Here's what is surprising...
These mice were being purposely overfed.
Type 2 muscle fibers didn't just make them stronger, it made their metabolisms work better.
“This work shows that type 2 muscle just doesn’t allow you to pick up heavy objects, it is also important in controlling whole body metabolism".
“It appears that the increase in type 2 muscle fiber orchestrates changes in the body through its ability to communicate with other tissues".
Type 2 fibers are increased through strength training.
They don't add much overall size to the muscle.
This is a GOOD thing, in my opinion.
This is a way to become stronger and lean without looking bulky.
My new book '12 Weeks Physical Transformation Journey' emphasize this type of training.
So you can look sleek in or out of clothing.
My program involve at least 3 hours per week of exercise.
I would probably sell more if I said "you can get your dream body in just three 20 minute workouts per week"...
...but I really do believe we need to consciously increase the time spent exercising due to our inactive lifestyles.
Never too early to begin using exercise to protect the body against aging.
