Combat sports
A combat sports fitness program genuinely doesn't look like any other: power has to stay fully available after several minutes of intense effort, not just on a single maximal one.
Combat Sports specifically builds power and robustness over a full 9 weeks at three sessions a week, with specific cardio that mimics round intervals rather than plain continuous running. Neck and core strengthening fully rounds out the program, two key areas that take a heavy toll on impact and get neglected everywhere else.
This program always fully complements technical training at the club, it never replaces it: boxing, MMA or grappling are only ever properly learned on the mat, with a real partner or coach right in front of you.
