Posted Thursday September 27, 2012 4:22 PM GMT

In an effort to shed extra pounds, Hilary Duff headed into her West Hollywood gym on Thursday (September 27).

The 24-year-old mom rocked a simple workout ensemble while she continues to battle her post-baby weight.

It appears the extra endorphin release gave the blonde beauty a boost as she tweeted, “Have a happy day ❤” after her workout.

In related news, Miss Duff will make an appearance on the current season of “Project Runway.” While judging the contestants, Hilary shared her fashion advice, saying, "I love that you can dress it up or down, and I love what mom is wearing as well.”

You can catch Duff on the Lifetime show tonight at 9 p.m. EST.
