The best way of lifting one’s hands after rukuʿ is to raise the hands lifting them from the knees as one starts straightening up, then  raising them to shoulder level as well as the head together (al-Kāshifah: 62), one’s fingertips are evenly aligned with the tip of the ears, thumbs aligned with the earlobes, and palms with one’s shoulders, fingers slightly outspread, the palms facing the direction of qiblah, saying, “samiʿaLlahu liman ḥamidah.” When one is standing upright, one then says, “Rabbanā lakal ḥamd.” (al-Majmūʿ: 3: 271-272)
When one rises up from the first sajdah, one raises the head  and sits before prostrating a second time, the best way is to say, “Allahu akbar,” as one raises the head (without raising one’s hands), to sit in “iftirāsh,” which is to flatten the left foot and to sit on the ankle while keeping the right foot on the bottom of its toes, heel up.

(iftirāsh)

Then one places both hands on the thighs near the knees, fingers extended and held together (ibid: 288), and then one recites the duʿā, “Rabbighfirlī, warḥamnī, wajburnī, warfaʿnī, warzuqnī, wahdinī, waʿāfinī, waʿfuʿannī.” (al-Tuhfah: 1: 301)

والله تعالى أعلم
Allah Most High knows best.
