Just hands or just legs

[ProfFilipe]

Does anybody practice the sequence moving only the hands and the arms. i.e, without the legs?

[ProfFilipe]

And the opposite, just the legs?

I do this only to help isolate corrections. If there's a persistent problem with my arms, I practice a few times moving only them and then practice with the legs. Note that the form is meant to be a whole-body routine.
