How to Do Good Mornings: Build a Stronger Posterior Chain

Good mornings are one of the most effective exercises for building posterior chain strength—your hamstrings, glutes, and lower back working together. They're also one of the most feared exercises in the gym, often avoided due to concerns about back safety.

Done correctly, good mornings are perfectly safe and incredibly valuable. Here's how to do them right.

Why Good Mornings Work

Good mornings train the hip hinge pattern with the load on your back, creating unique demands:

Muscles worked:

• Hamstrings (major emphasis)
• Glutes
• Erector spinae (lower back)
• Core (stabilization)

Benefits:

• Builds hamstring strength through a stretch
• Strengthens the lower back
• Improves hip hinge mechanics
• Transfers to deadlifts and squats
• Addresses posterior chain weakness

Good Mornings vs Romanian Deadlifts

Both are hip hinge movements, but:

| Good Morning | Romanian Deadlift | |---|---| | Bar on back | Bar in hands | | More lower back involvement | More grip demand | | Harder to go heavy | Can load heavier | | Greater forward torso lean | Slightly more upright |

Both are valuable. Good mornings offer unique lower back strengthening that RDLs don't match.

The Basic Barbell Good Morning

Setup

1. Position bar on upper back (high bar or low bar position)
2. Feet shoulder-width apart, toes slightly out
3. Slight bend in knees—maintain throughout
4. Core braced, chest up

Execution

1. Hinge: Push hips back while maintaining flat back
2. Descend: Lower torso toward horizontal
3. Depth: Go until you feel hamstring stretch (45-90 degrees of torso lean)
4. Return: Drive hips forward to stand
5. Squeeze: Contract glutes at the top

Key Form Points

Throughout:

• Back stays flat—never round
• Knees maintain same slight bend
• Weight stays mid-foot to heels
• Head neutral, following spine

At the bottom:

• Strong hamstring stretch
• Torso roughly parallel or above
• No rounding of lower back
• Controlled position

Finding Your Depth

Depth depends on hamstring flexibility:

Less flexible: Stop when back wants to round (maybe 45 degrees) More flexible: Can approach horizontal (90 degrees)

The rule: Go as deep as you can while maintaining a flat back. Stop before rounding occurs.

Common Good Morning Mistakes

1. Rounding the Lower Back

The most dangerous error. Immediately increases injury risk.

Fix: Reduce weight, reduce depth, focus on hinging not bending.

2. Bending Knees Too Much

Turns it into a squat instead of a hip hinge.

Fix: Set knee bend at the start and maintain it. Only hips move.

3. Going Too Heavy Too Soon

Good mornings don't need heavy weight to be effective.

Fix: Start very light. Master the movement pattern before adding weight.

4. Bouncing at the Bottom

Using momentum instead of muscle.

Fix: Controlled descent, brief pause, controlled ascent.

5. Hyperextending at the Top

Leaning back past neutral at lockout.

Fix: Stand tall with neutral spine. Squeeze glutes, don't arch back.

6. Looking Up

Cranes the neck and misaligns the spine.

Fix: Keep head neutral. Look at floor a few feet ahead at the bottom.

Good Morning Variations

Seated Good Morning

Removes leg drive, isolates lower back more.

How:

1. Sit on bench with bar on back
2. Feet wide and flat
3. Hinge forward from hips
4. Return to upright

Best for: Lower back isolation, those with hamstring limitations.

Banded Good Morning

Great for learning the movement pattern.

How:

1. Stand on band, loop over shoulders/neck
2. Same hip hinge movement
3. Band provides accommodating resistance

Best for: Warm-ups, beginners, high-rep sets.

Safety Squat Bar Good Morning

Easier on shoulders, different loading angle.

How: Same movement with safety squat bar.

Best for: Those with shoulder mobility issues.

Zercher Good Morning

Bar held in elbow crease.

How:

1. Hold bar in crook of elbows
2. Same hinge pattern
3. Core works even harder

Best for: Variety, increased core demand.

Single-Leg Good Morning

Unilateral version for balance and imbalance correction.

How:

1. Bar on back or hold dumbbells
2. Stand on one leg
3. Hinge forward, other leg extends back
4. Return to standing

Best for: Balance, addressing asymmetries.

Dumbbell Good Morning

Lighter option without a barbell.

How:

1. Hold dumbbells at shoulders or hanging at sides
2. Same hinge pattern

Best for: Home gyms, lighter training days.

Programming Good Mornings

For Strength

• 3-4 sets of 6-10 reps
• Moderate weight
• Focus on controlled movement
• Full rest between sets

For Hypertrophy

• 3-4 sets of 10-15 reps
• Moderate weight
• Emphasize the stretch at bottom
• 60-90 seconds rest

As an Accessory

• 2-3 sets of 10-12 reps
• After main squat/deadlift work
• Moderate weight

For Rehab/Prehab

• 2-3 sets of 12-15 reps
• Light weight or bodyweight
• Focus on movement quality

Weekly Frequency

• 1-2x per week
• Often on deadlift or squat days
• Allow recovery between sessions

Good Mornings in Your Routine

After Squats

Squat Day:

1. Back squat: 4 x 5
2. Good mornings: 3 x 10
3. Leg curl: 3 x 12
4. Leg extension: 3 x 12

After Deadlifts

Deadlift Day:

1. Conventional deadlift: 4 x 5
2. Good mornings: 3 x 10

2. Romanian deadlift: 3 x 10
3. Leg curl: 3 x 12
4. Back extension: 2 x 15

Safety Considerations

Start Light

Good mornings don't require heavy weight. Start with just the bar and add weight gradually over weeks.

Master the Pattern First

Practice the hip hinge with bodyweight or a dowel before adding a barbell.

Know Your Limits

Stop the set before form breaks down. A rounded rep is a dangerous rep.

Warm Up Thoroughly

Good mornings stretch the hamstrings under load. Cold muscles don't respond well.

Use Appropriate Equipment

Power rack with safety bars if possible. Drop the weight if you feel anything wrong.

Tips for Better Good Mornings

Feel the Hamstrings

The stretch in your hamstrings tells you you're hinging correctly. If you only feel it in your back, you're likely rounding.

Push Hips Way Back

Think about pushing your butt toward the wall behind you. This cues the hip hinge.

Maintain Tension

Don't relax at the bottom. Stay tight throughout the movement.

Progress Slowly

Add weight in small increments. Good mornings punish ego lifting.

Include Other Posterior Chain Work

Good mornings complement deadlifts and RDLs, not replace them.

Common Questions

Are good mornings safe? Yes, when done with proper form and appropriate weight. The danger comes from rounding the back or going too heavy.

How much weight should I use? Start with empty bar. Most people stay well below their squat weight—often 30-50% of squat max.

Good mornings vs RDLs—which is better? Both are excellent. RDLs allow more weight; good mornings train the back more directly. Use both.

Why does my lower back hurt after good mornings? Either your form is off (rounding), the weight is too heavy, or you're not used to the movement. Reduce weight and check form.

Should good mornings be heavy or light? Moderate weight with perfect form. They don't need to be heavy to be effective.

The Bottom Line

Good mornings are a powerful tool for building posterior chain strength. The key is respecting the movement—start light, maintain a flat back, and progress gradually.

Master the hip hinge pattern. Feel the stretch in your hamstrings. Keep your back flat no matter what. Do these things, and good mornings will build hamstrings and a lower back that support everything else you do.

Hinge correctly, load appropriately, and build a bulletproof posterior chain.
