Leg Lock Anthology: 50/50

By Lachlan Giles

View course on BJJ Fanatics

Leg Lock Anthology: 50/50 places defense inside a larger attacking game. Lachlan Giles covers heel-hook prevention and counters, reclaiming the knee and leaving 50/50, alongside entries, finishing mechanics, sweeps and back takes. The eight-volume series also includes narrated training and competition rounds. It suits someone who wants both sides of leg-lock exchanges, with a strong emphasis on 50/50 and outside sankaku.

Is this for you?

• You want heel-hook defense alongside the attacks and positional changes that create those exchanges.
• You want detailed coverage of 50/50, including knee recovery, sweeps and disengagement.

Also consider

John Danaher: Pin Escapes and Turtle Escapes — For mount and side-pin escapes when the main problem is upper-body control rather than leg entanglements.

Coverage and limits

• Knee-line and rotation concepts, heel-hook finishing mechanics, prevention and counters.
• 50/50 and outside sankaku, knee recovery, sweeps, back takes and disengagement; counters involving saddle, outside ashi and reaping positions.
• Entries from seated and open guards, entries from top, and narrated rolling.

Limits

• A substantial part of the course covers attacking entries and finishes. It is not a defense-only collection of escapes from every leg lock.
