Sporty: Jennifer Lopez and Alex Rodriguez leave Somi Fitness in Miami on Thursday

Proving that even a trip to the gym is a chance to show off her famous curves, the 47-year-old’s tight workout gear featured sheer panels and emphasized the Booty singer’s shapely backside.

Her hair was tied up into a tight top knot and miraculously did not appear to budge during the training session, as it was seen intact on her way out of Somi.

Jennifer and her 41-year-old former MLB player boyfriend arrived at the backdoor of the establishment just moments apart from each other.

Once they arrived, they both greeted the same man, presumably a trainer.

Alex held a drink in his hand as he made his way into the gym, the day after he posted a picture of him working out with Lenny Kravitz and WWE wrestler Big Show.

The former Yankee looked comfortable in baggy sweats and athletic shoes.

Lopez is keeping fit between gigs. Over the weekend she performed her first concert in the Dominican Republic with her ex-husband Marc Anthony joining her on stage.

A-Rod kept a close eye from the audience during the show.

In May, she will return to the Las Vegas stage for her hit All I Have show at the Axis Theater inside Planet Hollywood.

Lopez also has her NBC scripted drama Shades Of Blue which is currently airing, and reality dance competition show World Of Dance which premieres in May.

In the past, the Maid In Manhattan star has credited LA-based celebrity trainer Tracy Anderson with helping sculpt her figure.

Alex had to keep in tip-top shape for the 22 seasons he played Major League Baseball.
