Jennifer Lopez is taking no days off for the holidays ... looking absolutely stunning before hitting the gym on Christmas Eve.
Check out these pics of J Lo strolling into her Tuesday workout in Miami ... she's got her rocking bod on full display in skintight spandex, and she's feeling the Xmas spirit with her red gym attire.
J Lo's got the kind of booty Santa would love to see on his lap ... yes, Alex Rodriguez is one lucky man.
Judging by the looks of her smoking hot figure ... we're guessing A-Rod is NOT getting Jennifer a Peloton bike for Christmas.
