Good Morning (Barbell)
The Barbell Good Morning is a posterior chain exercise that strengthens the lower back, glutes, and hamstrings through a weighted hip hinge. By placing the load on the upper back, it creates a long lever arm that challenges core stability and hamstring flexibility.
Because Good Mornings place high demand on the spinal erectors, Iridium checks your 7-day workout history to confirm your lower back isn't pre-fatigued from recent squats or deadlifts. The AI tracks this specific volume against your Maximum Recoverable Volume to ensure you don't exceed your lower back's weekly work capacity. To manage fatigue on this hinge pattern, Iridium prioritizes RPE trends over aggressive weight progression significantly more than on stable compound lifts.
Form Cues
- Place the barbell across your traps, similar to a high-bar squat position
- Unlock your knees slightly and keep them fixed in that position
- Hinge at the hips, pushing your glutes backward towards the wall behind you
- Keep your spine neutral and chest up as you lower your torso
- Drive your hips forward and squeeze your glutes to return to standing
- Don't round your lower back at any point during the movement
- Don't turn the movement into a squat by bending your knees excessively
- Don't hyperextend your neck by looking straight up
- Don't lower the weight beyond your active range of hamstring flexibility
- Don't jerk the weight up; maintain a smooth, controlled tempo
Common Mistakes
- Rounding the lumbar spine
- Squatting instead of hinging
- Using excessive weight
- Locking the knees completely straight
- Looking up and craning the neck
Muscles Worked
This exercise is a primary builder for the erector spinae, which must work isometrically to keep the spine neutral against the load. It simultaneously stretches and strengthens the hamstrings and glutes, which act as the prime movers to extend the hips and bring the torso back to an upright position.
