suitcase
n.— «I recommend what a trainer once referred to as “suitcases” where you lie flat on your back, lifting your feet slightly off the ground, arms overhead slightly from touching the ground (this should tense up your abs) and bringing your knees and elbows together and crunching in one fluid motion (like closing yourself up in a suitcase, i guess). When you extend back out, don’t touch the ground, keeping the tension on your abs.» —“How to lose a tummy and love handles?” by nmp0906 Lose Love Handles Dec. 17, 2008.
