Of course, Jen looks incredible on every red carpet she graces, but she works hard to stay fit, strong, and on top of her game. Her personal trainer Leyon Azubuike, co-owner of Gloveworx, tells Women's Health that Jen works out up to seven days a week for an hour and a half each session, depending on where they are in her training cycle.
Azubuike uses a training technique called "periodisation" with Jen, which allows him to adjust 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." So, her workouts vary anywhere from three days a week at 45-minute sessions to those monster seven-workout weeks.
Still, her workouts are never easy. Since Azubuike and Jen both have chaotic schedules, they jump on any available time to break a sweat. "She has to respond when I say go," says Azubuike. "If she has a shoot at 3 a.m. and we need to work out before that, let’s go...we respect each other in that regard, so it’s a constant back and forth with mutual respect and understanding." And he admits he's a tough trainer, so "she definitely should be commended, because when I get into go mode, I’m in go mode."

"We box, we jump rope, we do strength training, we do a lot of work with resistance bands—we’re big on resistance bands," says Azubuike. "We rotate these things so it’s always hard, she’s consistently being challenged—I’m a big fan of switching things up, so the body reacts in a positive way and changes."
Azubuike says Jen loves boxing and core work. "Every core exercise I throw at her, she dominates it," he says. "She can hold a two- or three-minute plank rather easily."
To challenge her, Azubuike has Jen crank out a plank flow where she starts in a standard plank, then moves to a side plank, then moves to plank with shoulder taps, and so forth. "We do a lot of things that stretch the core, so we’ll do things where she’s hanging on a pull-up bar, then she pulls her knees up and brings them back down." She also loves doing V-ups and using ab wheel. "We’ll use a setup to shock the body occasionally, but it’s not a major part of our core regimen."
But don't worry, Jen isn't a master of everything in the gym—at least, not at first. Azubuike says she didn't love using the jump rope when he first introduced it into her routine because she found it a bit challenging (same). "I just made her keep on doing it, and now she’s great at it."
Azubuike says the hardest part of working with Jen is finding new ways to challenge her. "Here’s a woman who has always looked amazing, and I'm tasked with keeping it that way and elevating that even further."
Well, based on recent photos from her 50th birthday party, mission accomplished.
