Fitness with the fiance -- and we do mean "with!" Brooks Laich is a professional athlete, so he knows his way around the gym, but used his cutest "dumbbell" ever on Sunday: his fiance Julianne Hough.

Brooks shard a photo on Instagram of him literally using the "Dancing With The Stars" judge as his weight during a humorous workout session in Los Angeles.

Julianne, he said in the caption, "is definitely the prettiest weight I've ever lifted!"

He continued, "Fitness is and always should be fun - use your imagination and create the active and healthy lifestyle that you want! Let's see what you come up with!"

Brooks' fiance also shared the pic on her personal Instagram page, joking, "I'm just glad you didn't refer to me as your dumbbell 😜 #youraisemeup🎶."

Julianne can be seen laughing while her man picks up her petite frame, lifting her over his head.

The couple got engaged last year and still seem smitten with each other. Earlier this month, Brooks shared a beautiful shot of him and his wife-to-be.

"One year ago today I asked this beautiful soul to marry me, and thankfully she said yes!" he captioned the shot. "I am so grateful to share my life and love with you @juleshough - and I can't wait to marry you!"

Last year, not long after she said "yes," Julianne said she was in no hurry to head to the altar.

"We're just enjoying the engagement right now," Julianne told ET. "We're not really focused on that part yet."

Like Brooks, Julianne isn't above gushing about her beau.

I'm so lucky that you were born this day 33 yrs ago my love! I wish I could've known you as a kid growing up in wawota with your best buddies that are still your best friends to this day! To be able to witness how you became the man you are today. To watch how your parents raised you, Harold teaching you to fish, Jane always there to encourage you, how Jodi laughed at you putting the blow dryer in your mouth, and Jordan and yourself in your little hockey gear at such a young age! I know I missed all those birthdays, but I know we met at the perfect time in our lives to celebrate the next 90yrs together (cause you are convinced you can make it past 120 years old 💪🏼) I love you more than anything on this planet, and you make my eyes shine bluer than ever! Happy birthday my love ❤️
