Recently I've been studying FMA, specifically Kali Arnis, and their Rhythm Rumble Workout offered a fun and engaging alternative as well as a full-body workout that embodied a few similarities to Kali even if its origins are mainly from capoeira. I loved how every move was done to a lively beat and learning a whole new art while dancing my ass off!
It actually made me feel more limber - not to mention lighter - strong and free! I never felt more alive and pumped with any other workout, and since we get to "spar" with our partners, you'll really be forced to think on your feet in blocking and making offensive moves. It was such a great class that I brought my best girlfriend with me the very next day! Such fun!
