The Snapdown Setup
The snapdown is the key to the blast double leg. From collar tie or front headlock position, snap the opponent's head down by pulling their chin toward their chest. This breaks their level and disrupts their base — perfect timing for the shot.
From Snapdown to Shot
- Establish collar tie with hand on neck
- Snap the head down — opponent's eyes look downward
- As opponent stands up to recover level, immediately shoot
- Drive explosive leg extension through their hips
- Finish by controlling legs and driving forward
Power-Based Mechanics
Unlike the technical double leg that relies on precise mechanics, the blast double uses raw power and explosive leg extension. This makes it excellent for strength-trained athletes and wrestlers but less dependent on perfect form.
No-Gi Application
The blast double is significantly more effective in no-gi than gi because there's no lapel to establish grips from. Snapdown mechanics work better without fabric friction, and the explosive nature of the shot is harder to counter without grips.
Finishing the Blast Double
Once legs are controlled, drive forward with your hips. Unlike the technical double which prioritizes control first, the blast double prioritizes momentum and impact. This often results in a more aggressive landing and more scrambling but can catch aggressive opponents off-guard.

Common BJJ Problems & FAQ
This typically occurs when you're snapping your opponent's head down by pulling their chin directly towards your sternum, creating excessive cervical flexion. Instead, aim to drive your forehead into their upper chest or shoulder while simultaneously pulling down on their head, distributing the force across your upper back and shoulders rather than just your neck.
Against a larger opponent, focus on using their weight and momentum against them by initiating the snapdown with a strong pull and a slight lateral shift, causing them to over-extend. Then, as they step forward to recover, explode into the power shot by driving your hips low and forward, utilizing your legs to lift and off-balance their superior mass.
You are likely not generating enough forward momentum and power from your legs and hips. Ensure your penetration step is deep and your hips are driving forward and down, creating a solid base, before attempting to lift. The snapdown should be a prelude to the shot, not the primary force generation; the power comes from your lower body driving through.
