Groin strains show up when it's both tight and weak in the positions that matter.
When your leg gets pulled out and your pelvis has to keep up, that's when it gives.
Your groin has to stabilize while your body moves around it.
That's exactly what Copenhagen planks train. Most people jump straight to the longest lever before they can control the position.
Shorten the lever. Build control. Then lengthen it.
That's when it carries over to defending a takedown or posting in a scramble.
Train the patterns your body actually faces on the mats.
