I’m stuck

Hi there.

So I’ve just completed my level 2 fitness instructor course and now I’m doing my level 3 personal trainer course but I just feel like I’ve learned nothing from it, like the course doesn’t go into detail on how to structure a workout, how many sets and reps per muscle head to do, how to choose the right split.

I’ve been practicing with making workouts for fake clients but I feel like I don’t know anything like I’m getting stuck on knowing what movement to do first, how many sets and reps per movement, how many sets per session compared to per week

And it’s scrambling my head trying to work it out. I don’t know if this just means this isn’t for me or I don’t know.

Any opinions?
