A lot of respect for the men and women of OPD and the work they continue to put in on the mats.

FROM THE ARCHIVES

A great perspective on why jiu jitsu is such a good way to stay active as you get older.

It keeps you moving, challenges your body, improves flexibility, and gives you a workout that never feels repetitive.

Another reason to keep training.
