Fitness trainer Tim McComsey demonstrates the good morning exercise.
Grab a straight bar and place it across the rear of your shoulders as you would a power squat. Keep your stomach tight, chest high, and feet shoulder width apart. Begin by bending at the hips, moving them back as you bend over to near parallel. Keep your legs slightly bent. Reverse the motion by extending through the hips with your glutes and hamstrings. Continue until you have returned to the starting position. Repeat this movement for as many reps as you wish.
This is a great exercise for the lower part of the body and your core.
