PINK lost her baby weight by doing an intensive full-body workout.
The 'Blow Me (One Last Kiss)' singer got her rock hard abs back after giving birth to her daughter Willow in June 2011 by following Hollywood trainer Jeanette Jenkins' innovative exercise routine, dubbed the Burpee Push Shuffle.
Jeanette explained in a video for UsMagazine.com: "This is an amazing exercise that you can do in a boot camp or in interval training workout to help you burn calories and tone the entire body from head to toe."
The vigorous routine works every inch of the body and Pink regularly did short series of reps to gain back her enviable muscle tone.
In order to look as healthy as the singer, Jeanette - who also keeps Kelly Rowland in shape - revealed all you have to do is "take your feet hip distance apart, slap the ground, throw the legs back, give me push up, throw the legs back up, big jump.
"Shuffle to the right, touch the ground, shuffle to the left. Now try that one more time! Now do 15 more reps."
Pink, 33, has said in the past that the fitness maestro was relentless and credits her with helping her get fit quickly.
She told Shape magazine: "She kicked my butt more than any other person I've ever worked out with."
