Three minutes of a leg static exercise every day is going to be a thing that brings you the craziest of results.
Wall sit, horse stance, various other yoga inspired, karate inspired, weightlifting inspired positions (among others) will give you serious real world usable athletic strength.
I’ve said it a million times. Simple exercises done with dedication will give you results like most wouldn’t believe.
Just three minutes of training a day will give you a highly functional, extraordinarily useable strength in your legs.
I highly recommend the practice.
