بسم الله الرحمن الرحيم
There is difference in the postures of sajdah for man and woman. A man should keep his stomach away from his thighs and the arms from the sides while elbows and wrists above the ground, whereas a woman should attach her stomach with her thighs and arms with her armpit and her elbows and wrists to the ground compressing herself to the core. It is makrooh and against sunnah for women to perform sajdah like men.
Allah knows Best!
