Jennifer Lopez & Alex Rodriguez Get In a Workout with Lenny Kravitz!

Jennifer Lopez and Alex Rodriguez are always committed to their fitness and they got a friend to join them for a workout!

The hot couple was spotted at the Somi Fitness studio with pal Lenny Kravitz on Thursday afternoon (January 31) in Miami, Fla.

Jennifer and Alex spent the last 10 days doing a challenge in which they eat no sugar or carbs… and Jen is already ready for another round.

“Alright guys so I just got back from the gym. It’s day 10. Day 10! We did it; we’re here! I mean, we still have the rest of the day, but I’m feeling pretty good, like we can finish,” Jennifer wrote on her Instagram Story. “Anybody who has stuck with us through the whole 10-day challenge, congratulations.”

“Maybe we’ll stop for a few days and then get back on it, so you can join me for the second round,” she said.
