1. Rolling Side Plank
    Planks seem so simple since you’re on the floor and there are no weights involved, and yet, they suck so much no matter how often we do them. No pain no gain, so let’s get to it. Begin in a standard plank position, abs engaged, hands just below your shoulders, arms straight, legs extended and feet close together. Then slowly shift your weight into a side plank with your hips stacked and your top arm on your hip. Then return to the original plank and repeat on the other side. Do this repeatedly, alternating sides, for one minute.
