- excellent shoulder rotation
- excellent drive foward
- excellent athletic balance
when you turn to start your delivery cycle, you drop you arms, then when you start to deliver while moving forward - you bring your arms back up.
My suggestion would be to keep your arms (elbows) up, at least arm pit high, and continue your shoulder rotation and delivery. You’ll more than likely find a much better strike by location, and your fatigue rate will be less.
While your going through your motions inside your garage, I would suggest limiting your force to about 70%. Go easy on the deliberate hard throwing, for now.
I’m sure there will be other comments to help you, but for now, give my suggestions a try. By the way, when and if you do, you’ll notice a burn starting in your shoulders. When you do, shut down for a few minutes, roll you’re arms and shoulders around in a windmill - about 10 reps, hydrate (water), rest for a few minutes, then start again.
I make these suggestions considering that you have NO injuries in the past that will interfer with this format. So, I assume that you have no broken bones, dislocated shoulders, elbow problems, wirst problems or other things that might complicate your visit. (right?)
Other than that, you look very, very solid.
