It is recommended that one say takbīr while standing straight before going into rukūʿ, and for men to push back their knees when they are in rukūʿ.
It is also recommended for one to keep his back flat, stretch his neck forward and keep it in line with his back, look between his feet, invoke blessings (ṣalawāt) upon Prophet Muḥammad (Ṣ) and his progeny before or after the dhikr; and after rising from rukūʿ and standing straight, while his body is still, he should say: سَمِعَ اللهُ لِمَنْ حَمِدَهُ samiʿal lāhu liman ḥamidah Allah hears the one who praises Him.
