1. Lie on your left side resting your left forearm on the floor for support. Hold the dumbbell in your right hand.
2. Raise your hips up so that your body forms a straight line and brace your abs—your weight should be on your left forearm and the edge of your left foot. From this position, raise the weight in your right hand until your arm is parallel to the floor.
3. If the dumbbell or kettlebell you have is too heavy to perform a lateral raise with in this position, you can use a weight plate from the dumbbell (if it’s the plate-loaded kind), or simply skip the lateral raise and use the weight to resist your side plank.
