How do you practice when your swing is awful?

We all have seen the videos that go like “Do this practice routine at your driving range to improve” or “Practice like a PGA pro with this routine” and it’s 10 swings with a wedge, 10 swings with your 8 iron, etc.

Now, I’m not saying they are wrong at all with what they’re suggesting, but how does that routine work with someone who is awful at golf?

If I take 10 swings with my 8 iron, probably 7 of them will come out as a hosel rocket or I smack the turf mat behind the ball. I am just not good enough and figured out my swing yet to do that kind of practice.

I know it’s a stereotype of golfers to just come to the driving range and take a bunch of 100% swings with 2-3 clubs, but I honestly feel like that’s how I should be practicing + the drills I do also to hopefully figure out my swing.

Any advice on practicing when you are bad? Should I do the PGA routine, and just keep hitting until 10 good shots, then move onto the next club? It’ll probably take me 100+ balls to get through the full routine, but at least I could track my improvement with how fast I get through the full routine over time
