Exercising during the first few months of pregnancy keeps your fitness and energy levels up, reduces risks of complication during pregnancy, boosts your mood and eases back and pelvic pain. In the first trimester, you can take part in most of the exercises, like jogging, swimming, aerobics but you need to reduce the intensity.
The first trimester is a good time to start abdominal and pelvic floor exercises. After 12 weeks, one should avoid any curl-up exercises that you do while lying on the floor, although pelvic floor exercises can continue throughout your pregnancy. However, be cautious about your exercise regimen as not all exercises are safe during pregnancy. Remember to always warm-up before you do exercise and keep yourself hydrated while working out.
