What is meant by alternate direction?:)

Suddenly I've become in doubt of what is actually meant by alternating directions. For example I'm at SL/PE8, does it mean I have to perform 10 for each side, or a total of 10 reps? Im not a native speaker that might be why I'm confused and feel stupid

Kind Regards

Is it because my question is insanely idiotic, that no one has answered it yet?

Have you completed F1 yet? Because alternating reps is something that appears in a lot of exercises.

10reps alternating would mean alternating left and right, a total of 5 reps per side

Ah ok well thanks for clearing that up
