Squeak—
The chains and brackets made a piercing friction noise.
The 400-kilogram sandbag hanging in mid-air swung back and forth like a pendulum.
Fang Cheng extended his fists forward, assuming the classic Tiger-Stride stance of Muay Thai.
With a shout, he thrust his hips, flung his arms, twisted his body, and took a diagonal step to unleash a powerful kick.
Then he quickly retracted it.
What he was practicing at the moment was the iconic leg technique of Muay Thai, the Sweep Kick.
This stance is characterized by a higher center of gravity, with a slight tilt towards the rear leg.
It is conducive to enhancing the power of kicks and using the front knee to block attacks, and the separate hand positions also help maintain balance during a Sweep Kick.
The sandbag in front of him is the largest in the entire gym, specially used to practice heavy leg kicking techniques.
