The 45-year-old star reportedly works out in her hotel rooms with a yoga instructor demonstrating the exercises via video link.
Yoga instructor and author Mandy Ingber, who trains Jen and Kate Beckinsale, told The Hollywood Reporter sheโs helped the actresses stay fit over Skype.
โThey are Skype sessions,โ she said. โJen and Kate are very consistent. Thatโs why they like to continue to do their yoga practice, because it keeps them grounded. Staying present in a high-pressure situation where you have so much coming at you is gold.โ
Jennifer, who is engaged to Justin Theroux, told Womenโs Health earlier this year that a variety of exercise was the key to her slim figure.
โI have a lot of favorite workouts,โ she said. โI love cycling, I love yoga of course, and I recently started doing barre methodโwhich is painful and hard.โ
