Does exercise make you smarter?

Lessons from a Fit life.

The benefits of exercise keep piling up. Stronger, faster, leaner, smarter. Wait a second. Does exercise actually make you smarter?

Neuroscientist Wendy Suzuki “found that subjects who’d ridden bikes for an hour had markedly better scores on tests of their prefrontal cortex function than those who’d spent the hour watching an episode of 24 instead.” (That just seems like a needless dig at 24 (decent show). Imagine they force fed ‘The Kardashians’ instead…).

The cognitive improvement comes from as little as a few minutes of vigorous exercise and lasts :30 minutes to 2 hours following exercise. The benefits, markedly, include improvement in creativity, reasoning, memory, mood and communication.

So basically what I’m hearing is I don’t charge my clients enough.

I wrote a few weeks back about how Lebron James spending a million of dollars a year on his body made perfect sense. My reasoning: his investment would lead to more playing years at higher pay. One additional year for Lebron would pay for a 10 year investment.

Does exercise make you smarter?

Does the same reasoning apply to you? If exercise makes you stronger, faster, leaner, and smarter does that lead to more earning years at a higher pay for you? Does your elevated cognition make you better at work? At home?

Does it kinda pay for itself?

Before you answer that Go ahead and exercise for a minute. Get that brain sharp.

Now what do you think?

Yeah… I think we got the same answer.

Our teachers, I mean Trainers, are ready to help.

This phrase (Doc Levine’s) made us reevaluate sitting. According to Kelly Starret we should set our chairs at a height where “you can really use your legs to scoot powerfully back and forth” if you’re in an adjustable. Additionally we should sit upright, not leaning back “so you can turn on more musculature and build greater stability.”
It’s hot. Damn Hot. Real Hot. 4th of July weekend was THE HOTTEST weekend recorded. Ever. What can we do to beat the heat? We have AC, Central Air, wicking clothing and we’re still dropping like flies. Western Europe saw some 20,000 deaths in a recent unrelenting heat wave. It could happen here. And the heat will wreak havoc on your workouts too.
For the uninitiated Blue Zones are, in essence, places where life expectancy and quality of life are on a different level. People routinely live over 100 years and additionally stay mentally sharp for the entire ride.
