Vanilla ice cream, a plain cheeseburger, that little black dress—sometimes keeping it simple is the most satisfying thing you can do. That goes for the core move you’ve probably done in almost every workout class of your life: the side plank. Sure, holding a straight line isn’t as exciting as bicycle crunches, but it’ll make you more functional both in the gym and IRL. Side planks are all about strengthening the side body and stabilising your spine. ~ Berceste
