The I'm A Celebrity… Get Me Out Of Here! contestant was pictured going make-up free as she arrived for a workout in Woodland Hills, LA on Monday.
Kendra said: "Starting my New Year resolution TODAY! I will have the body of my dreams by my 30th birthday which is June 12th."
She added the hashtags, 'Ready, set go', 'Get it' and 'Work'.
Kendra has just returned to LA from three weeks in the Australian jungle, taking part in the latest series of I'm A Celebrity.
And while we'd probably still be lazing around the house, eating everything in sight after a diet of rice and beans, she's already getting started on her healthy resolution.
It hasn't all been healthy for Kendra since getting back home, however, as she tweeted at the weekend she was suffering the effects of a hangover while chilling with her kids on Sunday.
Kendra shared a very cute picture of herself lying on a sofa alongside Hank Jr, five, and seven-month-old Alijah, with the caption: "This is what my day looked like today. #sunday #hungover #football #family #food."
She also joked: "Don't give a s**t what I look like lol."
