Former New York Yankees slugger Alex Rodriguez and his girlfriend Jennifer Lopez broke a sweat during their fitness routine, as the two were spotted at the gym A-Rod has ownership in. 

Check out the pics below: 

In addition to the his-and-hers workout at the UFC Gym, the couple were joined by Olympic swimmer Ryan Lochte and pregnant wife Kayla Rae Reid. 

 Jennifer Lopez and Alex Rodriguez are reportedly back on their extreme diet.  

It looks like the A-list couple is cutting back once again, at least according to Page Six, after seeing the pair at a University Of Miami baseball game on Saturday.

During their stop by the ball field, which is named after the MLB alum, they were spotted turning down the famous Mark Light Shakes, causing many to think the duo are dieting again.

Exciting stuff.
