The side lunge (aka lateral lunge) is designed to light up your glutes, particularly your glute medius (the muscle on the outside of your butt), while also working your quads and abs. Feel free to add a bicep curl to target your arms, as shown.
- Start standing with your feet hip-distance apart. Hold a weight in each hand with your arms by your sides, palms facing in.
- Take a big step to the right, and lower down into a lunge, keeping your left leg straight and lowering both weights to the ground on either side of your bent right leg. Keep your chest lifted, back flat, and toes pointing forward.
- Push off with your right foot to step it back to center and return to standing. (To add a bicep curl, perform it now, bringing the weights toward your shoulders and returning them to your sides.) That's one rep.
- Do the same number of reps on both sides.
