The groin is one of the places we don’t think too much of; until it gets hurt, of course.
This is a particularly sensitive spot, in my opinion. Maybe it is because it is in the immediate area of the genitals, and sometimes the pain in the groin radiates in that direction. Or maybe it’s because we use the muscles all of the time without realizing it.
Either way, I would advise against doing anything to strain that particular area. I know, anyone active enough to do so probably run the risk of getting hurt on a regular basis. It’s just that this place is a tough one to grin and bear through.
