"I love to walk for fitness. I love to do light weights to get strong and stay strong. I like to stretch and do yoga. Mixing it up is really fabulous. That way, you're surprising different muscle groups, and you kind of keep everything going and not plateau.CLICK HERE TO SIGN UP FOR THE ENTERTAINMENT NEWSLETTER"I really think anybody that enjoys what they're doing maybe it's pickleball, tennis, any form of fitness just move. Move as often as you can. Standing up burns more calories than sitting down."Austin, who has sold more than 24 million exercise videos and DVDs throughout her career, authored a dozen books and starred in a fitness television show, said there's one simple trick anyone could do to stay fit and lose weight."My favorite tip, I tell everybody, is good posture. Posture tells a lot about somebody," Austin said. "If you're slouched over, first of all, your tummy has nowhere else to go but out. But if you sit up nice and tall, put your shoulders down and back and zip up those abs."Keeping your spine healthy is so important. And then when you're standing up nice and tall, you can kind of tighten up your tummy for five seconds. That's equal to one situp. So, you could be doing these isometric exercises throughout the day that really work your muscles."
