I highly recommend Capoeria for conditioning, flexiblity and flow.
And my teacher was very good at Qinna, Brazilian style. But this is not commonly taught, as are the hand techniques, for about ten years into training. And I am not sure if most younger teachers know this aspect.
An old version of this art is to spar or Joga De Capoeria with unfolded straight edge razors between your first and second toe. In the US, the edges are taped. No blocking here, just learn to get out of the way and counter. Blocking their kicks, without razors, will get your arm broken anyway.
