“It is quite normal for those who exercise regularly pre-pregnancy to continue this throughout pregnancy, which can of course aid in post-pregnancy weight loss.
“That being said, exercise post-pregnancy would largely depend on the type of pregnancy that Princess Beatrice experienced.
“While it is normal to begin exercising soon after giving birth, depending on the trauma to the body, it may differ from person to person.
“I imagine that providing Princess Beatrice’s birth was healthy, then she would have certainly implemented some cardio and resistance training to aid her in losing weight.”
Women’s health and fitness coach, Beth Davies, elaborated on Princess Beatrice’s exercise routine to lose her post-pregnancy weight.
