I’ve been working hard lately at improving my hip-shoulder rotation. I have found a couple things to be helpful in my improvement.
Stretching–You’re body will only move in ways that your muscles, joints, and ligaments will allow. I spend 15-20 minutes each day stretching my hip flexors, quads, hamstrings…One of my favorite isolation stretches is lying on my back flat on the ground and then alternating putting each knee across my body to the ground. I’m not exactly sure what the stretch is called.
Front Shoulder Awareness–Every pitch, concentrate hard on keeping your lead shoulder pointed at your target. I imagine my front shoulder leading me down a steep hill and it seems to help.
…as mentioned in a previous reply, nice, fluid arm action will help precipitate proper shoulders. Remember, turn over your plant foot, then rotate the hips, then finally the shoulders.
Practice it a thousand times at home -> Turn over back foot, rotate hips, turn shoulders and flex forward. Even if you do it slowly, your body will remember the motions. You’ll be more apt to incorporate it in your game-speed delivery if your muscles remember the proper sequence.[/b]
