"HARD STYLE" WHAT DOES THAT MEAN?

COMPRESSION!!

Compression of the muscles. Muscles produce force by tensing. Maximize the tension. Compression of the joints. Keep joints tight and compressd to avoid injury and leakage.
Compression of the breath. High intra abdominal muscles increase strength.
Compression to the ground. Maximize stability.
Compression of focus. Focus the scattered energies of the body into a directed all out effort.

Study on this!!
Watch closely your fellow students that do it every time. (Donna, Rachael, Christina, Tim)
Compress, compress compress...

"HARD STYLE": Kinetic linkage from the ground up eliminating linkage.
