A strong core is about much more than having visible abdominal muscles. Your core helps stabilize the spine, support posture, improve balance & make everyday movements safer and easier. The good news is that you do not need a gym or special equipment to build core strength. Many of the best exercises for core strength use only your body weight and can be done at home.
As a licensed Naturopathic Doctor and primary care healthcare provider with nearly 20 years of clinical experience, I have observed that people often think of the core as just the abdominal muscles. In reality, the core includes the muscles of the abdomen, lower back, pelvis, hips & diaphragm. In my opinion, the goal of a good core workout should be function first. A strong core should help you move better, reduce strain & support the activities you do every day.
What muscles make up the core?
The core is made up of several muscle groups that work together.
These include:
- Rectus abdominis
- Transverse abdominis
- Internal and external obliques
- Multifidus
- Pelvic floor muscles
- Diaphragm
- Gluteal muscles
- Muscles around the hips and lower back
This is why core strengthening exercises should include more than crunches. A balanced program should challenge stability, rotation, anti rotation, hip control & spinal support.
Why core strength matters
Strong core muscles can help with:
- Better posture
- Improved balance
- Safer lifting
- Better athletic performance
- Reduced strain on the lower back
- Improved walking and running mechanics
- Greater stability during daily activities
Through my education as a Naturopathic Doctor, I learned how closely movement and musculoskeletal health are connected. In practical clinical experience, I have observed that poor core control often shows up as low back discomfort, reduced balance, or difficulty with basic movement patterns. Sometimes as a doctor, we need to understand that weakness is not always obvious. A person may appear fit but still have poor core control.
Best exercises for core strength
The best exercises for core strength are usually simple, controlled & easy to progress.
1. Dead bug
The dead bug is one of my favourite bodyweight core exercises because it teaches core control while the arms and legs move.
How to do it:
- Lie on your back
- Lift your arms toward the ceiling
- Bend your hips and knees to about 90 degrees
- Slowly lower one arm and the opposite leg
- Keep your lower back gently supported
- Return to the starting position
- Repeat on the other side
This exercise is excellent for beginners.
2. Bird dog
The bird dog works the core, hips & back.
How to do it:
- Start on your hands and knees
- Extend one arm forward
- Extend the opposite leg behind you
- Keep your hips level
- Hold briefly
- Return to the start
- Repeat on the other side
This is one of the best core training exercises for improving balance and spinal control.
3. Plank
The plank is a classic core bodyweight exercise.
How to do it:
- Support yourself on your forearms and toes
- Keep your body in a straight line
- Tighten your abdomen
- Avoid letting your hips sag
- Hold for 10 to 30 seconds
As strength improves, increase the hold time gradually.
Bodyweight core exercises can improve stability, posture, balance & spinal control without the need for weights or gym machines.
4. Side plank
Side planks target the obliques and lateral core muscles.
How to do it:
- Lie on your side
- Support your body on one forearm
- Lift your hips
- Keep your body in a straight line
- Hold briefly
- Repeat on the other side
A modified version can be done with the knees bent.
5. Glute bridge
The glute bridge strengthens the hips and helps support the pelvis.
How to do it:
- Lie on your back
- Bend your knees
- Keep your feet flat on the floor
- Tighten your core and glutes
- Lift your hips
- Pause
- Lower slowly
Although it is often viewed as a glute exercise, it is also useful for core stability.
6. Mountain climbers
Mountain climbers combine core control with cardiovascular work.
How to do them:
- Start in a high plank position
- Bring one knee toward the chest
- Switch legs
- Keep your hips controlled
- Move slowly at first
Speed is not the goal. Good form is more important.
7. Hollow body hold
The hollow hold is a more advanced exercise.
How to do it:
- Lie on your back
- Lift your shoulders slightly
- Raise your legs
- Keep your lower back supported
- Hold the position
If this is too difficult, bend the knees.
8. Reverse crunch
Reverse crunches target the lower abdominal muscles.
How to do them:
- Lie on your back
- Bend your knees
- Bring your knees toward your chest
- Lift your hips slightly
- Lower slowly
Avoid using momentum.
9. Heel taps
Heel taps are an easy option for beginners.
How to do them:
- Lie on your back
- Bend your knees
- Lift your shoulders slightly
- Reach toward one heel
- Alternate sides
This exercise targets the obliques.
10. Bear hold
The bear hold challenges the entire core.
How to do it:
- Start on your hands and knees
- Lift your knees a few centimetres off the floor
- Keep your back flat
- Hold the position
This is one of the most effective core workouts with no equipment options.
Core exercises at home
A simple core exercises at home routine can include:
- Dead bug
- Bird dog
- Plank
- Side plank
- Glute bridge
- Heel taps
You do not need to perform every exercise in one session. Choose four to six movements and complete two or three rounds.
Core workouts without weights
One of the advantages of core workouts without weights is that they can still be very challenging.
Bodyweight exercises improve:
- Stability
- Coordination
- Endurance
- Balance
- Muscle control
As a wellness specialist, I believe bodyweight training is often underestimated. Properly performed core workouts without weights can be highly effective.
Best core workouts for women
The best core workouts for women are not fundamentally different from those for men.
Women benefit from the same principles:
- Progressive resistance
- Good technique
- Core stability
- Hip strength
- Pelvic floor control
- Full-body strength
However, life stages can influence how core training should be approached. When it comes to pregnancy, postpartum recovery & menopause, pelvic floor health and core coordination may need more attention. Not all patients are equal based on age and gender because hormones, pregnancy history, pelvic floor health & previous injuries can affect how the core functions.
Core strengthening exercises are most effective when performed consistently two to four times per week and combined with full body strength, mobility & regular physical activity.
What about crunches & sit ups?
Crunches and sit-ups are not necessarily bad, but they should not be the only core exercises you do.
A balanced program should also include movements that resist:
- Extension
- Rotation
- Side bending
Examples include:
- Planks
- Side planks
- Dead bugs
- Bird dogs
These exercises often provide more functional core training than repeated crunches alone.
Core training & low back pain
Core weakness can contribute to poor spinal control, but low back pain is more complex than weak abdominal muscles alone.
Pain may also be related to:
- Joint problems
- Disc irritation
- Poor hip mobility
- Muscle tension
- Previous injury
- Prolonged sitting
- Poor movement patterns
Sometimes as a doctor, we need to put ourselves in the person's shoes. Someone with back pain may be afraid to move, but complete inactivity can sometimes make stiffness and weakness worse. The right exercise plan should be tailored to the individual.
Common mistakes during core exercises
Avoid these common errors:
- Holding your breath
- Moving too quickly
- Using momentum
- Arching the lower back
- Letting the hips sag
- Doing too many repetitions
- Ignoring pain
Good form is more important than quantity.
How often should you train your core?
For most people, core training two to four times per week is enough.
Your core is also trained during:
- Squats
- Lunges
- Walking
- Running
- Carrying
- Resistance training
You do not need to train it every day because recovery matters too.
The naturopathic approach to core health
Naturopathic Doctors are highly trained primary care healthcare professionals who consider the broader factors that affect musculoskeletal health.
Assessment may include:
- Pain history
- Posture
- Physical activity
- Previous injuries
- Weight
- Nutrition
- Sleep
- Inflammation
- Ergonomics
- Mobility
- Strength
We need to understand the patient deeply to provide holistic treatment. A strong core is one part of a healthy movement system. Strength, flexibility, balance, recovery & good movement habits all matter. When it comes to working professionals who sit for long periods, I have observed that short strength and mobility sessions often provide more benefit than waiting for one long workout at the end of the week.
Final thoughts
The best exercises for core strength do not need to be complicated. Simple bodyweight core exercises such as dead bugs, bird dogs, planks, side planks & glute bridges can build strength without equipment.
The most important factors are:
- Good technique
- Consistency
- Gradual progression
- Balanced training
- Proper recovery
Through nearly two decades of clinical practice, I have learned that core strength is not about chasing visible abs. It is about creating a stable foundation for movement, posture, balance & long-term physical health.
Core exercises can support posture, balance, stability and daily movement, but the right approach depends on your body, lifestyle, mobility and wellness goals.

FAQ’s
What exercise works the core the most?
The plank is one of the best exercises for working the core because it trains the abdominal muscles, back muscles, shoulders, hips and stabilizing muscles at the same time. A strong plank teaches the body to stay controlled and aligned, which is important for posture, balance and everyday movement. However, the “best” core exercise depends on your fitness level, form and goal.
What are the big 3 exercises for the core?
The “Big 3” core exercises usually refer to the McGill Big 3: the modified curl up, side bridge and bird dog. These exercises are often used to train core stability without excessive twisting or bending of the spine. They focus on control, bracing and spinal support rather than just doing fast ab movements.
Is 20 minutes of core enough?
Yes, 20 minutes of focused core training can be enough if the exercises are done with proper form, control and consistency. A good core routine should include stability, strength and breathing control instead of only crunches. Core training works best when combined with a balanced fitness routine that also includes strength training, cardio, mobility and flexibility.
How to fix a weak core?
To fix a weak core, start with simple stability exercises such as planks, dead bugs, bird dogs, bridges and side planks. Focus on slow movement, proper breathing and keeping your spine stable. Build gradually instead of rushing into advanced exercises. If you have back pain, injury, osteoporosis, or other health concerns, speak with a healthcare professional before starting.
What are three physical signs of a weak core?
Three physical signs of a weak core may include poor posture, lower back discomfort and difficulty with balance or stability. A weak core can also make daily movements, lifting, bending, or exercise feel harder because the muscles around the trunk and pelvis help support the body during activity.
