Good Mornings: Complete Guide to This Underrated Posterior Chain Exercise

Good mornings are one of the most underrated exercises for building posterior chain strength. They target the hamstrings, glutes, and lower back in a unique way that complements squats and deadlifts.

Here's how to do them safely and effectively.

What Are Good Mornings?

Good mornings are a hip hinge movement with a barbell on your upper back. You bow forward at the hips (like saying "good morning" with a bow), then return to standing by driving your hips forward.

They look simple but require solid technique to perform safely.

Why Good Mornings Work

Unique Loading

The barbell on your back creates a long lever arm that intensely loads the posterior chain. This stimulus is different from deadlifts or RDLs.

Hamstring Emphasis

Good mornings put significant stretch on the hamstrings under load—one of the best ways to build hamstring strength and size.

Lower Back Strength

The erector spinae work hard to maintain spinal position. Good mornings build the lower back strength needed for heavy squats and deadlifts.

Carryover to Other Lifts

Powerlifters use good mornings to strengthen the exact muscles that get challenged when a squat turns into a "good morning squat" (torso pitching forward).

Muscles Worked

Primary:

• Hamstrings
• Glutes
• Erector spinae (lower back)

Secondary:

• Core (stabilization)
• Upper back (supporting the bar)

How to Do Good Mornings: Proper Form

Setup

1. Set up a barbell in a rack at upper chest height
2. Position the bar on your upper back (like a high bar squat)
3. Grip the bar comfortably
4. Unrack and step back
5. Feet shoulder-width apart, slight bend in knees

The Movement

1. Brace: Take a breath, brace your core hard
2. Hinge: Push your hips back while keeping your back flat
3. Lower: Continue until you feel a strong hamstring stretch (torso roughly parallel to floor for most people)
4. Pause: Brief pause at the bottom
5. Rise: Drive hips forward to return to standing
6. Squeeze: Contract glutes at the top

Key Points

• Back stays flat: No rounding at any point
• Knees have slight bend: Not locked, not deeply bent
• Weight in mid-foot/heels: Don't shift onto toes
• Controlled tempo: No bouncing or jerking
• Hips go back: It's a hinge, not a bow

How Deep Should You Go?

The depth depends on your hamstring flexibility:

• Most people: Torso reaches roughly parallel to the floor
• Very flexible: May go slightly below parallel
• Less flexible: Stop when you feel significant hamstring stretch

The rule: Only go as deep as you can while maintaining a flat back. If your lower back rounds, you've gone too far.

Common Good Morning Mistakes

1. Rounding the Lower Back

The problem: Spine curves as you descend Why it matters: High injury risk with load on spine The fix: Reduce depth; only go as far as your mobility allows

2. Going Too Heavy

The problem: Weight is beyond what you can control Why it matters: Form breakdown, injury risk The fix: Start light; this is not a max-effort exercise

3. Bending the Knees Too Much

The problem: Turns into a weird squat Why it matters: Loses hamstring emphasis The fix: Keep a slight, consistent knee bend throughout

4. Looking Up

The problem: Craning neck to look forward Why it matters: Strains cervical spine The fix: Keep head neutral, eyes following the floor

5. Bouncing at the Bottom

The problem: Using momentum to reverse direction Why it matters: Reduces muscle work, risks injury The fix: Pause briefly at the bottom, then drive up controlled

6. Not Bracing

The problem: Loose core throughout Why it matters: Spine not protected The fix: Brace hard before each rep; maintain throughout

Good Morning Variations

Seated Good Morning

• Sit on a bench with bar on back
• Hinge forward from the hips
• Eliminates legs, isolates lower back and hamstrings
• Good for beginners to learn the hinge

Banded Good Morning

• Resistance band around neck and under feet
• Light resistance, good for warm-ups
• No spinal compression

Safety Squat Bar Good Morning

• SSB allows more upright torso
• Easier on shoulders
• Different feel, still effective

Zercher Good Morning

• Barbell in the crook of elbows
• More core emphasis
• Uncomfortable but effective

Single-Leg Good Morning

• One leg, bodyweight or light dumbbell
• Balance challenge, addresses imbalances
• Start with bodyweight

Programming Good Mornings

For Posterior Chain Development

• Frequency: 1-2x per week
• Sets × Reps: 3-4 × 8-12
• Load: Moderate (not a max-effort exercise)
• When: After main squat/deadlift work

As a Squat Accessory

• Strengthen the muscles that fail when squats turn into "good morning squats"
• 3×10 after squatting
• Moderate weight, focus on form

As a Deadlift Accessory

• Builds the hip hinge pattern and lower back strength
• 3×8-10 on deadlift day or separate day
• Complements RDLs

For Beginners

• Start with bodyweight or empty bar
• Focus on the hip hinge pattern
• Progress weight slowly over weeks
• Never prioritize weight over form

How Heavy Should You Go?

Good mornings should be done with moderate weight relative to your squat.

General Guidelines

• Start: Empty bar to 65 lbs
• Intermediate: 95-135 lbs
• Advanced: 135-225 lbs
• Rarely heavier than 50% of your squat

Why Not Heavy?

The lever arm makes good mornings very challenging for the spine. Heavy good mornings are unnecessary and risky for most people.

Focus on: Controlled reps, full stretch, solid form

Good Mornings vs. Romanian Deadlifts

Both are hip hinge exercises. How do they differ?

| Aspect | Good Morning | RDL | |--------|--------------|-----| | Bar position | On back | In hands | | Spinal loading | Higher | Lower | | Hamstring stretch | Similar | Similar | | Lower back work | Higher | Moderate | | Weight used | Lighter | Heavier | | Risk profile | Higher | Lower |

Use both: RDLs for heavier hinge work; good mornings for specific lower back and posterior chain focus.

Safety Considerations

Good mornings have a reputation as a "dangerous" exercise. The truth:

• They're safe when done correctly with appropriate weight
• They're risky when done heavy with poor form
• The spinal loading is the concern—respect it

Safety Tips

1. Start very light: Learn the movement with minimal weight
2. Progress slowly: Add weight gradually over weeks
3. Never round your back: If form breaks, the set is over
4. Use a rack with safeties: In case you need to bail
5. Don't max out: This isn't a max-effort lift

Sample Workouts with Good Mornings

Posterior Chain Day

1. Romanian deadlift: 4×8
2. Good mornings: 3×10
3. Leg curls: 3×12
4. Back extension: 3×15

Squat Day Accessory Work

After squats:

1. Good mornings: 3×10
2. Leg press: 3×10
3. Leg curls: 3×12

Lower Back Focus

1. Deadlifts: 4×5
2. Good mornings: 3×10
3. Back extension: 3×12
4. Plank: 3×45 sec

The Bottom Line

Good mornings are a valuable exercise for:

• Building hamstring and lower back strength
• Improving the hip hinge pattern
• Strengthening weak points in squats and deadlifts

Key points:

1. Keep your back flat—no rounding
2. Use moderate weight—this isn't a max-effort lift
3. Control the movement—no bouncing
4. Only go as deep as your mobility allows
5. Progress slowly and respect the spinal loading

When done correctly, good mornings build a stronger, more resilient posterior chain. When done incorrectly, they're risky. Master the form first, keep the weight reasonable, and you'll benefit from this underrated exercise.
