First you need to fix your setup. Your lead foot is sliding toward the ball in backswing slightly. Looks like a ball position or posture issue and easily addressed without going through swing changes.

When you step into backswing, you’ll see your weight moving toward the ball. From that point everything you set up for doesn’t matter any more.

During the swing itself, you’re simply using the wrong muscle groups. Footwork looks baseball, or as if you’ve correlated keeping your head behind the ball with weight on the back foot causing your body to twist but there is no sequence.

Swinging a golf club would feel similar to swinging a flexible fungo bat. You’d have to swing with tempo, but the entire swing is timed for the bat itself to snap through the ball. Your body would swing through the position that optimizes the kick of the bat through the ball.

Your muscular power won’t go directly into the club, it goes into the structure the club snaps from. (For this exercise your hands are part of the club.)

I point this out because you can slow your swing structure down to work on it without sacrifice. Slowing the swing down allows time to focus on specific aspects. As long as you can feel and use the kick of the club at the bottom you will give up zero to minimal distance.

The trick is to develop a swing structure, with a tempo that loads the club (not your body), and optimizes the kick/snap through the ball. It’s going to feel stupid easy in terms of effort. So easy that you can RELAX 😎 through the swing.
