Watch the The Whole Fretboard: Aeolian online guitar lesson by Robbie Calvo from Power Play: Minor
Improvise using pace, dynamics and crescendos over the 4 Aeolian key changes.
Remember to resolve your phrases to 'Sweet Note' chord tones and try to target the characteristic note of Aeolian, the b6th.
You have the entire fretboard now to express yourself. Phrase simple ideas that build to a crescendo in each of the keys. Once you have completed a full track (4 sequences) take a break, get up and move around, stretch and clear your mind.
You don’t need to use the entire fretboard if you don’t want to but maybe you could challenge yourself to work with as many patterns as possible just for an exercise. Treat that as a separate workout session if you’d like, observing the break times that I’ve suggested.
