Meet the "World's Strongest Mom"

Aol.com: Meet Aleesha Young, who has been a professional bodybuilder for half her life. But despite all the hard work that goes into preparing for competitions, her biggest accomplishment is being a wife and a mother. With biceps over 18 inches and quads over 28 inches, Young may be considered the World's Strongest Mom.

"I think people in the fitness world are surprised that I'm a mom because it's pretty rare at my level of female bodybuilding," Young explained to AOL Lifestyle.

"I knew that being a mom was a number one priority for me -- it had to happen for me," she continued. "I couldn't give the sport everything I needed to until I had my little girl." After Olivia was born, it took Young 10 months to get back into competitive shape.

And now, Olivia even helps out with her mom's fitness routine by adding weight to her mom's pushups and lunges. See more of Young's unconventional story in the video!

Female bodybuilder Janice Lorraine is Australia's toughest grandma

TheMorningShow: Janice Lorraine is a 76-year-old grandmother, and she's claimed 12 world titles in the past two decades. The former psychologist trains at the gym for three hours a day, three days a week. On the other days, she recovers with an 8km walk. She's been competing in bodybuilding for the last 20 years. "When I started, there was nobody my age," Lorraine said. "I was 56 then, and gradually it's grown. "I get a lot of Facebook messages from people all over the world, mainly 50-plus. They're all so excited."

Dealing with trolls
While most of the feedback Lorraine receives is positive, she's had to deal with critics and trolls - mainly from men. "I get called old duck, old bag, old chook," Lorraine said. "In 2013, I was on my way to training for the championships in Greece. "A neighbour of mine, two years younger than me, he said, are you still doing that bodybuilding? "I said yes, and he said, it's about time you gave that up - you're well past your used by date. "I didn't want to waste my time putting those thoughts in my mind and dwelling on them. "I take (the criticism) and use it in a positive sense, in order tell others that you should be able to live your life to the full, and follow your dreams no matter how old you are."
