Place the bar on the back as you would for a back squat. Position your feet far wider than your squat stance—the actual width will depend on your flexibility and intent. The feet should be turned out slightly.
 
Brace the trunk forcefully with the lower back neutral or slightly more extended and the upper back flattened as much as possible.
 
Bend the knees very slightly as you hinge at the hips as far as you’re able without losing back extension. Bend forward at a controlled speed, and recover at a natural to quick speed.
 
Maintain whole foot balance or shift slightly more to the heels, but keep the whole foot in contact with the floor.
 
Don’t allow your back to soften as you change direction in the bottom to stand again—resisting that force with a rigid trunk is a primary element of the exercise.
 
The knees can be bent more to shift more of the work to the glutes than the hamstrings, or can be locked straight to maximize hamstring emphasis.
 
Notes
This variation of the good morning places far more stress on the hamstrings and in a different manner—ease into them and be very conservative with loading and volume until you know how you handle them.
 
Purpose
The wide-stance good morning emphasizes the hamstrings and adductors more than a good morning, and can be used as loaded, active flexibility work.
