Curtis, 33, told her nearly 11 million followers on the social platform: "Just need to share! I'm so kilig. So, when I started running, the form of my legs started to change. I gained a lot of muscle. And in the beginning I was kind of scared as to what people might have to say as I'm on TV everyday where the camera angle isn't always flattering."

With a 20-year career in showbiz, Curtis has long been a familiar face to television viewers. Notably, she became a household name whose career skyrocketed when she joined ABS-CBN's "It's Showtime" in 2009. For a greater part of her career as an adult, Curtis also became a sought-after fashion model, bringing to view her lithe frame.

But for some seven years now, Curtis' physique, by her own admission, has become more muscular, thanks to her passion for running.

Referring to her insecurity about how running has changed her body, she tweeted: "I decided to not care. I love running so much. And to my surprise, sa last Instagram post ko, where you can clearly see my defined calves and thighs, instead of comments such as. 'Ay, ang laki ng pata,' I see more comments like, 'Calves,' 'Thighs look strong,' 'Toned legs.'"

I also have those kind of thighs. Patatim talaga datingan. People say running daw talaga maganda sa ganun. I join fun runs and do joggings before but I stopped when we moved in to another location. Is it really helpful? Will go back to it talaga. @annecurtissmith
