About 15 years ago I had an accident that left me with chronic pain in the area of the groin where the leg muscles of my right leg have their attachment points. About 10 years ago I had surgery for an inguinal hernia including implanting a surgical mesh to keep all the right bits in the right places. Since then the pain has greatly reduced and only flairs up when I do broom handle sweeps (which can really stress the tendons/cartilage in the groin) or when I go all out on a kicking bag which, again, puts ballistic load into the tendons/cartridge in the groin) . Once inflamed it takes around two months to subside. I have recently realised that although I am OK at most forms of power generation (rib cage power / c backs / spirals and hip shake, etc) I generate virtually no power with my legs. So can anyone suggest drills or exercises for gradually building leg power? I am most interested in use of leg power in bridging, hand techniques, locks or throws rather than for kicks. Low impact would be preferable. Any suggestions gratefully Received .
