Even after pregnancy, it didn't take long for her to return to her original self. Wondering how she managed to do that? Amrita had told mid-day back then, "I started slow and steady by alternating weight training, cardio and yoga. I decided that I'll not kill myself in trying to get back to my original self."

"But let me tell you that after a baby, a woman's metabolism is excellent, which actually helps her lose weight if done in the right way," she concluded.
