Liz Hilliard, who is 70, has always been active. In school, she was an athlete, and she’s enjoyed all the fitness trends that have come and gone over the decades. (Anyone else take step-aerobics in the ‘80s?) In her 40s, Hilliard fell in love with Pilates, known for improving balance, flexibility and core strength. She enjoyed it so much that she became a certified Pilates instructor.

But in her 50s, she noticed that she was carrying a little more weight around her midsection than she used to. As with many women in menopause, she saw an increase in belly fat and a decrease in muscle. But when she started working out differently, all of that changed.

Curious as to what worked for her? Here, Hilliard gives the low-down and shares the exact workout moves she does regularly.
