Though the always amazing Grisha Goryachev primarily plays flamenco guitar, the videos he posts are so beneficial for classical guitarists, too, that they deserve a spotlight on them. I’ve always thought flamenco players in general had more power in their right hands due to the extensive extensor muscle development as a result of contant rasgueados. So after trying these two guitarless warmups that Grisha posted and judging by how tired my extensor muscles felt, I think they will at least help balance out the musculature of my hands and forearms. The other benefit of trying these warmups is to experience the natural movements required of the hand and fingers and the foundation they provide for the fine motor skills of playing. Try them and let me know what you think!
