When it comes to planning for pregnancy and increasing your BMI, both yoga and strength training can play beneficial roles, but they serve different purposes.

Yoga for pregnancy can be incredibly advantageous as it not only enhances physical fitness but also promotes mental well-being, which is crucial during the preconception period. The gentle stretches and breathing exercises in yoga can help alleviate stress, improve flexibility, and enhance circulation, all of which contribute to reproductive health. Additionally, specific yoga poses can target muscles important for pregnancy and childbirth, such as the pelvic floor muscles.

In conclusion, while both yoga for pregnancy and strength training have their advantages, incorporating a combination of both into your preconception routine can provide comprehensive benefits. Remember to consult with a healthcare professional or a certified trainer to tailor a plan that suits your specific needs and goals.
