I honestly don't need to say this, but Jennifer Lopez has got it going on. Yes, genetics plays a role in her amazing figure, but she also works her ass off in the gym.
When I got the opportunity to work out with her trainer, David Kirsch, I couldn't pass it up. Yes, I'm a personal trainer, but I do enjoy being in the student position and having someone else guide me through a workout.
David took me through an intense full-body workout, and one part that stuck with me was the plank series he had me do. It challenged my strength and stability, and I cannot wait for you all you try it. Check out the 4-move workout ahead.
