Does sati require vāyāma?

It seems while cetanā concerns having a goal, vāyāma is what carries this goal out. My understanding is neither vāyāma nor cetanā *should* involve upādāna; however, vāyāma is outside of and cultivates the ālaya. If any of this is wrong feedback would be welcome, but my question is does sati require vāyāma, or can it be the result of bountiful ālaya? Does sammā-vāyāma become less significant with cultivation?
