A floor roller is the best
The price went up to 20,000-30,000 won recently, so I got one cheaply.
If I use it at home, I can apparently see the faces of people downstairs
So I got permission from the apartment complex gym and used it there, felt refreshing~
(In a corner during off-peak hours when people aren't around)
But once I tried it, it's about 1.5 times harder than a treadmill. I'm not sure if it's because it's not a metal drum, but it's a great workout.
