I can’t think of many good reasons against getting stronger.
Yes, we can move heavy things. But that's the tip of the iceberg.
Physical strength is the foundation of other physical qualities – power, speed, endurance, agility, balance…
When we’re older, strength can give us quality of life – protect us from falls, do day-to-day stuff (perform well when we’re 90, 100)…
Strength can be the gateway to building other types of strength – mental, emotional…
And, less known, it’s incredible for our brain.
See, when we do strength training, our muscles contract.
That contraction floods our body with these hormones called Myokines (there’s 100+ different types of them).
Specific Myokines benefit our immunity, metabolism, muscle growth and more.
But what’s cool is that Myokines also cross the blood-brain barrier. They surge into different parts of the brain, improving our:
Myokines (by definition) only release when a muscle contracts.
So the only way to get the benefits is through movement. Particularly, resistance training.
Neurophysiologist Louisa Nicola says we have to lift weights at or above 70% of our 1 rep max (aka pretty heavy) to really get the benefits.
One more reason to get strong.
