Jennifer Cohen What We're Buying

Jennifer Cohen, fitness expert and author of Strong Is the New Skinny: As a busy mom who is constantly on her feet all day, it is extremely important to prepare for my day the morning or night before. This is why my Merin bag is my everything! It not only is oversize, being big enough to carry everything I need for the day, but it’s fashionable too.

What I pack in my bag is even more important. First and foremost, I can never leave home without having a handful of KIND bars — portable and delicious. Another must is Aquaphor since I wear it on my lips to moisturize all day, my Polar RC3 heartrate monitor to track all my daily activity and an extra sports bra and tank top to have to change into. I (of course) always carry a few extra diapers and wipes too (for my son!) but that’s not so stylish — just super practical.

Jennifer Cohen is a lifestyle and fitness spokesperson, KIND bars brand ambassador and TV personality. Her new book Strong is the New Skinny is available now, and follows the success of her 2009 bestseller No Gym Required – Release Your Inner Rock Star. For more, follow her on Twitter.

Lola Astanova, musician: To me, “effortless” also means “amazing” when it comes to style. And my Tiffany 1837 sunglasses effortlessly combine the legendary Tiffany design with everyday functionality. I can wear them behind the wheel and on the beach, when I go shopping or when I go out, and they have already traveled with me to Europe and all over the U.S. Their shape brings a simple elegance to every outfit, while the Tiffany Blue adds a subtle touch of chic, which always makes a girl feel special.
