Lateral lunge – We Heart Living

Side lateral lunges

Stand with your feet hip-width apart while holding a dumbbell in both hands by your sides. Step out to the side with one leg, allowing that knee to bend and making sure the other is straight and both feet are flat on the ground. Return to the start position by pushing up through the heel of the bent leg. Repeat on the other side, alternating sides through the entire set.
