Ick, yuck, beurk!
Denise Austin IS very annoying. On the videos and shows I've seen, she talks to exercisers as if she's talking to 4 years olds. She also has a voice that's like nails on a chalkboard, and mentions "bra overhang" a lot, and says we're going to "burn that butter."
She also has an odd, boogie-eyed look about her, like she never blinks.
At best, she's "perky." At worst, overly so.
She just comes over as 'dumb as a post" to me, and she's hawked some really stupid fitness gadgets (like a neoprene wrap that she kept saying would help you lose weight, but the host of the QVC show she was hawking on kept correcting her and saying that it was temporary water weight loss, because they didn't want false claims).
Don't like her. Can you tell?
(She may have gotten better in recent years, but I tried her years ago and will never try again. The titles and descriptions of some of her more recent workouts look good , see www.collagevideo.com
