Peta Murgatroyd is getting pumped for her summer wedding!

The Dancing With the Stars pro took to Instagram on Tuesday to give her fans a sneak peek at how she's getting in shape so she can look her absolute best when she says "I do" to Maksim Chmerkovskiy next month at Long Island's Oheka Castle. The secret? A little strength training help from their 5-month-old son, Shai!

Murgatoryd returned to DWTS just two months after giving birth to her first child, which helped her shed the baby weight tremendously. But now, she's stepping up her workout game even more. The 30-year-old dancer has adorably been using her little bundle of joy as her main source of weight in the gym.

In the sweet Instagram video, we see Shai has been helping his mama sculpt her booty, legs, arms and abs!
"Less than three weeks until the wedding!" Murgatroyd captioned it. "Love our family sweat sessions with @timhartwigtrain! #workforit #fitmom #workingmom."

The blond beauty shared a similar video earlier this month, which featured Shai flashing a smile as his mom worked on her lunges. Chmerkovskiy also made an appearance as the two passed their newborn back and forth for a fun family ab workout.

It doesn't get much cuter than that!
