The Gym Issue

Welcome to The Gym Issue of Polar Journal—your friendly backstage pass to the wonderful, sweaty world of strength training.

In this edition, we’re digging into everything from the science behind a really satisfying rep (the kind that makes you nod like, “Yep, that was the one”) to the rise of hybrid athletes who mix endurance and power like it’s the world’s healthiest cocktail. It’s gym talk, but without the grunting.

Whether you’re a seasoned lifter, a curious newbie, or someone who just enjoys the vibe of neatly stacked dumbbells, this issue brings a fun, fresh look at what really goes on behind the barbell. Grab your towel, take a sip of something cold, and come on in. The gym floor is open.
