Left Hook. Boxing
The left hook trains rotational power generated from the hips and transferred through the torso into a short, tight punching arc — it's a boxing fundamental, not a muscle-isolation exercise. Most of the power comes from pivoting the back foot and rotating the hips, not from swinging the arm, which is the single biggest technical error beginners make.
