Good Mornings is a unique resistance training exercise that works your lower back as well as gluteus and hamstrings muscles. Make sure that you perform this exercise with a proper technique to avoid lower back injuries. The weight of the bar should be medium so that it does not compromise the integrity of your spine.

In order to begin this exercise, stand straight with your feet shoulder width apart and place a weighted bar on your shoulder area. Next step is to bend at your waist until your upper body is about parallel to the ground. Make sure that you keep your back straight. Return to the starting position to complete one rep. Perform 3 sets, 10-12 reps each.

Back exercises would yield best results if you consume diets that help increase the strength and endurance of muscles. Lean meats, fruits, vegetables, nuts and whole grains contain nutrients that help gain lean muscle mass and increase vigour and strength of muscles.

It also makes a good idea to use a dietary supplement that strengthens the muscles.
