The country singer took to Instagram on Tuesday to update fans about her post-baby weight loss journey.
Sharing a shot from her gym routine, Decker looked gorgeous while going makeup-free clad in a blue T-shirt and black leggings.
"Workin hard!! 5 lbs away from my pre Bubby weight and 10 pre Vivi! I work out two times a week and eat well making mostly all my meals at home but still have my sweets and treats!" she posted with the pic.
"@anthonymichaelfit knows how to help post baby mamas like me:) I feel healthy and happy and that's all that matters. Not trying to starve myself because that would just be silly and would take away from the good milk I make for my baby!" she continued. "When I'm hungry I eat! Toning up and living a healthy lifestyle is my goal right now:)"
The brunette beauty likewise shared a super sweet snapshot cuddled up to her baby boy, Eric Thomas Decker II, earlier this week. "Bubbylicious," she simply captioned the candid.
Jessie and hubby Eric Decker welcomed their baby boy together in September, and little Eric joins the couple's 1-year-old daughter, Vivianne Rose Decker.
