A recent Instagram post from the acclaimed entertainer shows elite trainer Anna Kaiser putting Shakira through the oblique workout of death: The singer-songwriter targets her side abs by keeping her back flatter than she would for a normal side crunch and, with her hips twisted to one side, she pulsates up and down with her belly button tucked in and a finger on her abdominals to ensure she’s activating them to the fullest.
If you think you can follow that act, try her wall sit routine. She’s posted against a wall squeezing a med ball between her legs and holding weights in each hand; the wall sit works the quads and hamstrings, the med ball squeeze lights up the inner thighs, and the isometric 90-degree hold fires up the biceps for a full-body twist on a gym class classic. If you’re already against a mirror, try the banded wall squat, which adds hip mobility and lowers your chance of injury when it’s time to hit the real squat rack.
Targeting all sides of your torso is a must for developing a serious six-pack, and Shakira demonstrates that with her deceptively difficult ab routine.
