Say Auf wiedersehen to shlumpy workout wear thanks to Heidi Klum's latest gig.

When the supermodel isn't rocking the runway, the mother of four often finds herself running around town going to meetings or driving carpool.

What she wasn't finding, though, were casual, fashionable outfits to wear. "I don't want to squeeze myself into the tightest jeans and high heels first thing in the morning," Klum, 37, told

So she then decided to take things into her own hands. The result was the Heidi Klum for New Balance sold exclusively on Amazon. "I wanted to do a collection for women, like me, who are busy with children and work," she said.

The collection includes tops, bottoms, jackets and dresses (ranging from $32 to $168) that Klum describes as "comfortable and chic."

Although she is proud of all the pieces, she admits to playing favorites. "I'm obsessed with the oversized hooded poncho! It's so comfortable and cute. I'm also a hug fan of the women's long sleeve asymmetrical jacket," she told Us. "It's not necessarily something you would wear to the gym, but it's great to throw on after to look put together."
