Our hips are the base of our core. Many of the muscles that support our torso originate in our hip girdle, so it's paramount to have a strong, supportive base of control in our hips. My favourite tool for healthy hips are what I call 'smarter strength' exercises. These are moves to engage varying muscles of the hips in a functional way.
The biggest challenge that most women face when it comes to exercising during pregnancy and postpartum (other than getting motivated, ha!) is that we don't have enough specific direction. We are given a lot of general recommendations that make it tough to know exactly what to do when we exercise.
