Jailhouse rock (52 blocks)
Jailhouse Rock, also referred to as 52 Blocks, is a striking art originating in the United States. It is classified as a striking system rooted in an African-American improvised boxing tradition. The style developed outside formal institutional structures, and its training centers on stand-up striking methods drawn from that informal, adaptive background.
As a striking art, training in this family of discipline generally focuses on stand-up techniques, hand positioning, and the development of reflexes and physical conditioning suited to close-range exchanges. Practitioners typically drill offensive and defensive movements from a standing position, with an emphasis on adaptability and responsiveness that reflects the improvised nature of the tradition from which the style emerged.
Individuals who are new to this style are encouraged to locate schools or instructors in their area, observe a class in person, and speak with current students before committing to training. Watching a session directly provides a clearer sense of the instruction style and environment than any written description can offer.

Gear to expect. Striking training typically calls for gloves, hand wraps, shin guards, and a mouthguard — your school will tell you exactly what, and when. New students rarely need to buy anything for a trial class.
