Gordon Ryan explains how the berimbolo changes without the gi: tight-waist grips instead of the collar, the knee-behind-knee position and what to do when the opponent throws their back flat.
The Mendes brothers teach their berimbolo at Art of Jiu Jitsu: shin control, the front-roll style inversion, hooking the hip after the spin and switching grips to finish on the back.
Very detailed breakdown of the berimbolo inversion and then finishing with a leg drag instead of the back, including how to keep the far leg controlled once you come out of the roll.
A no-gi De La Riva back take that steers the opponent over with the legs instead of a full inversion, with fallbacks to single-leg X when they post heavily.
Seminar footage of Paulo Miyao teaching his De La Riva grips and berimbolo entries, including what to hold when the belt is not available. Long and unpolished but from one of the best to ever do it.
Back takes from DLR against opponents who weave a hand through the legs, plus the triangle and omoplata that appear when they break your grips. Narrated over class footage.
