Smith Machine Good Morning
The Smith machine good morning is a hip hinge with a guided barbell across your upper back. You push your hips back with a soft knee bend and return by driving them forward. It loads the hamstrings, glutes and spinal erectors, and the fixed bar path removes balance demands so you can concentrate on the hinge.

What muscles does the smith machine good morning work?
Primary movers
- Hamstrings
- Gluteus maximus
- Erector spinae
Assisting muscles
- Adductors
- Core
- Upper back
The hamstrings and glutes control the lowering as your hips travel back, then drive the return. The longer the torso lever, the more demanding the movement, which is why it stays much lighter than a deadlift.
The erector spinae work isometrically to hold your back flat against the bar load. This makes the exercise a serious lower-back builder, and also the reason to be conservative with weight.
On a Smith machine the bar cannot drift forward or tip. That removes a lot of the stabilisation demand and lets you feel the hinge more clearly, though your feet have to sit slightly forward of the bar path.
Because the load sits across your back, it works well for the hamstring stretch but is hard on the spine if you add weight too fast. Treat it as an accessory.
How to do the smith machine good morning
Setup
- 1
Set the bar at upper chest height and place it across your upper back as you would for a squat.
- 2
Step your feet slightly forward of the bar so your hips can travel back without hitting the track.
- 3
Use a shoulder-width stance with toes slightly out.
- 4
Brace your abs, keep a soft bend in your knees and rotate the bar to unhook it.
Execution
- 1
Push your hips back as if closing a door behind you.
- 2
Keep your back flat and your knees softly bent throughout.
- 3
Lower until you feel a strong hamstring stretch or your torso is near parallel.
- 4
Pause briefly without losing tension.
- 5
Drive your hips forward to stand tall.
- 6
Re-hook the bar when the set is finished.
Common smith machine good morning mistakes
Going too heavy
The lower back carries a long lever, and a rounded spine under load is risky.
The fix: Start with light weight and add slowly. Many lifters use only 30 to 40% of their squat.
Squatting the movement
Bending the knees too much turns it into a half squat and removes the hamstring stretch.
The fix: Keep a soft, constant knee bend and send the hips back.
Rounding the back
A flexed spine under load shifts stress to the discs and ligaments.
The fix: Stop the descent as soon as your back starts to round.
Feet too far under the bar
Your hips run out of room and the bar pushes you onto your toes.
The fix: Place your feet slightly in front of the bar track.
How many sets and reps?
| Goal | Sets | Reps | Load | Rest |
|---|---|---|---|---|
| Hypertrophy | 3 | 8–12 | Light to moderate | 90 s |
| Strength | 3 | 6–8 | Moderate | 2 min |
| Beginner | 2 | 10–12 | Empty bar | 60–90 s |
Use it after your main squat or deadlift for extra hamstring and lower-back volume. Progress slowly and keep the movement smooth.

Frequently asked questions
Is the Smith machine good morning safe?
It is safe with a flat back, light loads and slow progression. Most problems come from using too much weight.
What does it work?
The hamstrings, glutes and lower back, with the core and upper back stabilising.
How heavy should I go?
Much lighter than your squat. Aim for controlled reps in the 8 to 12 range.
Why use the Smith machine?
The guided bar removes balance demand so you can focus on pushing your hips back.
How is it different from a Romanian deadlift?
The weight sits on your back instead of in your hands, which lengthens the lever and loads the lower back more.
