Last week Kelly Rowland tweeted a picture of her doing an intense abdominal workout with celebrity trainer Jeanette Jenkins.

In the picture of the two Kelly said:

The girl is killin me, killin me, killin me. Ahh, she’s killin me!

Rowland is seen trying to giggle the pain away but no pain, no gain! And Kelly knows that!

On the same day Jeanette tweeted:

If you want it bad enough then you’ll be willing to put in the work.

Jenkins is not fooling around when it comes to fitness. She is a celebrity trainer, NIKE Training Club ambassador, nutritionist, author, FITNESS Magazine advisory board member, producer, speaker, consultant and entrepreneur. Her mission is to use the experience and education she has gained through her schooling and throughout her life to teach and inspire men and women to live the healthiest life they could live.

Kelly Rowland and Jeanette Jenkins are the now the “Commanders” and command you to find your “Motivation.” The tag team even released a workout DVD, titled ‘Sexy Abs’. The DVD will give fans unique access to  the same midsection sculpting exercises that have helped shaped Kelly’s own sexy abs, with her own trainer and music throughout.
