Chris you are correct on that one.
It took everything in my power to keep that racquet headed over my shoulder. Which caused big time stiffening of the arm. I will try to relax more next time. Problem was when I relaxed on the first video I was following under the shoulder
Yeah - your torso/feet are not moving and you are hitting everything with the arm, and this will feel unnatural.
Your set up is good - but once you start swinging, you drop the left arm, arm the racquet into your body (without any extension forward) and then extend out the right and left arms sideways because you have a mental image of finishing over the the shoulder.
Try this - freeze and hold the racquet at contact and see how it feels for two seconds, before you follow through. In your video, the contact is close to the side of your body.
In contrast, a professional forehand will contact well forward of their body, continue even more forward, and then take a good step forward with the right leg (if a righty) to bring the body around - this finish of the right shoulder, right elbow, and the butt of the racquet pointed to the target are the real signs of the modern forehand, where you hit with the hips and not the arms.
It helps me to think of the ground stroke as a linear movement in the line of the ball, and not as a circle - more like a box - straight in a line through the ball, across the body, and then (with a big step) around the body.
also - don't jump at the ball, stay down and hold the same vertical plain. Otherwise, the timing/aiming gets too hard and you will shank. You see pros jump, but if you look in slo-mo, it comes after the contact from the weight shift and not from trying to jump up and into the ball.
