She was spotted leaving a pilates studio after getting her workout on.
After pilates, spinning and circuit training stopped being so effective, she turned to boxing to bust through her plateau!
Her trainer said:
"Her main love is boxing. We skip rope and run boxing intervals with one minute of rest between. It's important to find an activity you love so that you look forward to the workout. Hilary comes ready to train with a smile on her face because she loves the challenge of something new. She was really looking for a workout that was challenging and to be pushed to the limits of what she could do physically."
She took to boxing several times a week and it really worked!
She fought her way back into size 8 jeans!
Way to get fit, gurl! Lookin' great!
