Kim & Kourtney Kardashian's Big Apple Workout

Supporting each other's physical fitness efforts, Kim and Kourtney Kardashian were spotted heading to the gym in New York City today (August 31).

The E! reality television starlets both looked sporty as made their way to their afternoon workout, all the while waving to the swarm of relentless paparazzi stationed nearby.

Meanwhile, Kim recently told press that - when creating the Kardashian Kollection for Sears - she wanted to make sure everyone could enjoy the fit, no matter what size or shape they may be.

The 30-year-old stunner told press, "Usually when I buy clothes off the rack, I need to have them adjusted. So for this collection, we made sure each dress had an hourglass shape. We also used stretchy fabrics; the pieces have lots of stretch and hold so you feel secure."
