Running form/ cadence/ maximising form

Im a intermediate runner, following my own made structured trainint plan

5k: 22:00

10k: 48:00

Male 23 yrs 179,5cm 79,5kg

Just for info.

I was wondering if anyone has some tips on getting at better running form/ higher cadence? No Metronome/ counting stuff like that. More like form tips/ drills/ workouts?

I cant seem to get it higher. For ref at 6:30 pace its around 147 average

At 4:30 around 160/165

And at 3:30 around 175/180
