Work your abs, lower back, hamstrings, and quads with this body-toning move.
-Lunge Hinge: Stand three feet in front of a step or stair holding medium weights in your hands. Lunge back and put your right foot on the step. Bend both knees 90 degrees and then stand up, squeezing your glutes. Hinge forward at the hips and raise your right leg off the step so it's parallel with the floor and lower your hands toward the floor. Now, push back into the lunge with your right foot on the step and repeat for 12 to 15 reps. Now, switch sides, lunging back with your left foot on the stair. Then hinge forward and raise your left foot. Repeat the lunge and hinge on this side for 12 reps. This move works your lower back and abs and your hamstrings and quads.
