I've been testing the 'Inverted W' for my arm action style to see what kind of results it can bring to me. Yesterday, I did some drills, and threw on the mound for roughly 70 pitches with the arm action. I thought: not bad, and if I can get it consistent, I can be good with this. My knuckle curve looked nasty with Inverted W arm action. But the problem is... arm concerns.
Right now, my arm feels fine after doing some Jobes exercises with a rotator cuff exercises that I learned. But with the high elbow and rather excessive use of shoulder, some people say it can damage my pitching arm. Here's a good article that explains the weakness of Inverted W:
Thing is that, I feel good doing the Inverted W than other arm actions (and I feel I can repeat it more consistently), but it can give injury risks. Should I stay, or change my arm action back to slinging arm action? Any opinios? Thanks
