Be flexible with your workoutsEverybody has someplace they need to be, and Jennifer is no exception. Azubuike told Women’s Health that he uses a training technique called "periodization" with Jen, which adjusts things based on her schedule. "Depending on where we are in that cycle dictates the duration and intensity of Jen’s workout," he says.

"If I know Jen isn’t filming anything, it’s a different phase than if I know she has something coming up tomorrow. If she’s going to be walking up to receive an award, I’m not going to destroy her legs in the gym the day before."
