I’ve often wondered why we don’t see the anchor foot used more in MMA.
The anchor foot is an alternative to double hooks. You see it often in folkstyle wrestling. You have one leg (or hook, as BJJ guys will call it) in. Instead of throwing the second boot in, you have the second foot go in between the opponents’ legs from behind and under the shin. You can put a lot of pressure from there if you put your hips in, and you’re way less likely to get too high than double boots.
Islam had the anchor foot in when he got the sub. It’s a great position and I think fighters should use it more.
