Clinch Lesson 1 - Single Under-hook & Knee Strike

Updated: Dec 12, 2023


This is the first lesson in our Clinch 101 series.

The under-hook is a great offensive technique that you can use when in the clinch. The single under-hook occurs when one of your arms goes under the assailant's arm/armpit, while in the clinch. You can control the assailant by pulling them down to meet your strikes. You can also use the under-hook to move them forwards, backwards, and to either side.


How to perform the single under-hook

  1. Facing the assailant (your partner in practice), bring your left arm underneath their right arm (same side) until your bicep/shoulder is pinned into their arm pit.

  2. Clasp that hand with your other hand and pull him down to control him. Alternatively, you can grab your chest with your under-hook hand, leaving your other hand free to strike with.

  3. Do not lean back or reach up too high; doing so will put you off balance. If they are too tall, use a different clinch (you'll learn more clinches in the upcoming weeks).


The first strike from the single under-hook clinch is the knee to the groin:
  • From the single under-hook, pull the assailant down as you drive your knee straight up into the their groin. The rear knee strike will have more power than the lead knee strike, but use either if the other cannot reach their groin.


Below is a video showing how to strike the groin while using the single under-hook.
