Barbell Good Morning

Set up with a barbell across your upper traps, just as you would for a squat. Stand with feet hip-width apart and a slight bend in your knees. Hinge at the hips and push your glutes back, lowering your torso until it is roughly parallel to the floor or until you feel a strong stretch in your hamstrings. Drive your hips forward to return to standing, squeezing your glutes at the top.

Pro Tips

• This is a hip hinge pattern with the bar on your back — treat it like a standing RDL
• Maintain a neutral spine throughout; rounding under a barbell load is dangerous
• Use significantly less weight than your squat — the lever arm is much longer

Muscles worked

Primary: Hamstrings — the hip-hinge movement loads the hamstrings through a long lever arm (bar on the upper back, hinging at the hip), producing significant eccentric and concentric loading of the biceps femoris, semimembranosus, and semitendinosus.

Supporting: Gluteus maximus (hip extension on the return), erector spinae (isometric lumbar extension to maintain a neutral spine throughout), core (bracing against forward-flex load).

Common mistakes

Rounding the lumbar spine: This is the primary safety concern in the good morning. The long lever arm created by the bar on the upper back and the hinged torso places enormous force on the lumbar spine if the back rounds. Neutral spine must be maintained from setup to completion. If the weight forces rounding, reduce it immediately.

Treating it like a squat: The good morning is a pure hip hinge with minimal knee bend — not a squat with a bar on the back. If the knees are bending significantly and the hips are not pushing back, you are performing a partial squat.

Loading too heavily: Because the lever arm is so long (distance from hips to bar is the whole torso length), even moderate weights create significant spinal loading. Many experienced lifters use good mornings with 40–60 percent of their squat weight. Start conservatively and build over months.

Not feeling the hamstrings: If you feel the good morning in your lower back rather than your hamstrings, the hips are not pushing back far enough. The hamstrings should be under a clear stretch and tension at the bottom of every rep.

Programming notes

The barbell good morning is primarily used as a posterior chain accessory in powerlifting and strength-focused programmes, where it develops the hamstrings and lower back in the specific position they are loaded during the squat and deadlift (loaded hip hinge with a neutral spine under axial load). It is particularly valuable for lifters whose squat breaks down at the bottom — where the good morning mirrors the torso angle and demands the same musculature.

Typical programming: 3–4 sets of 6–10 repetitions at the end of a lower body or deadlift session, as a supplemental exercise rather than a primary lift.

Frequently asked questions

Is the barbell good morning safe to do?

Yes, when performed with a neutral spine and an appropriate load. The exercise has a long lever arm — the bar sits on your upper back, and the torso acts as a moment arm from the hips — which multiplies compressive and shear forces on the lumbar spine. That makes technique non-negotiable: if your lower back rounds at any point, the weight is too heavy. Start light, build the movement pattern over weeks, and treat it as a technical lift rather than a load-chasing one.

How much weight should I use on good mornings?

Most experienced lifters work good mornings with 40–60 percent of their squat weight, and beginners should start even lower. The long lever arm means that a weight that feels trivial in a squat can be genuinely demanding in a good morning. Load is less important than maintaining a neutral spine and feeling the hamstrings under tension. Build the movement for several months before adding meaningful weight.

What is the difference between a good morning and a Romanian deadlift?

Both are hip-hinge movements that load the hamstrings and glutes, but the bar position changes the mechanics. In an RDL you hold the bar in your hands, which shortens the lever arm and limits how far the load can travel from your base of support. In a good morning the bar sits on your upper traps, creating a longer lever arm that places greater demand on the erector spinae to maintain neutral spine. Good mornings reinforce the upper-back and spinal position specific to the squat; RDLs are generally more hamstring-isolated and easier to load progressively.
