The couple that does sweaty yoga together, stays together??
Seems to be the case with Alex Rodriguez and Jennifer Lopez ... who hit up a group Hot Pilates workout class at TruFusion in the Miami area -- and put in that work!
J-Rod seemed to enjoy it ... doing breath exercises, chopping moves, dancing and posing for selfies with everyone in the class.
They also threw fake money to promote J Lo's new song, "Dinero," with Cardi B and DJ Khaled.
The people in the class loved it -- and gave the couple an ovation after the workout. J Lo rewarded the group with a little dance number.
Good times.
