13 Best Yoga Poses For Core Strength
1. Plank Pose (Phalakasana)
Why it helps: This pose is a full-body strengthener that engages the entire core, including the transverse abdominis, the deepest abdominal muscle.
How to do it:
- Begin in a push-up position with hands under shoulders.
- Engage your abdominal muscles, keeping your body in a straight line from head to heels.
- Hold for 30 seconds to 1 minute, breathing steadily.
Tip: Avoid letting your hips sag or rise too high — think of your body as a strong, straight plank.
2. Boat Pose (Navasana)
Why it helps: Targets the upper and lower abdominals, strengthens hip flexors, and improves balance.
How to do it:
- Sit on the mat with legs extended.
- Lean back slightly and lift your legs to a 45-degree angle.
- Extend arms forward, keeping your spine straight.
- Hold for 20–30 seconds and repeat 2–3 times.
Myth Buster: Many believe that crunches are the only way to work the abs. Boat Pose activates deeper core stabilizers that crunches often miss.
3. Bridge Pose (Setu Bandhasana)
Why it helps: Strengthens the glutes and lower back while stretching the chest and shoulders, promoting better posture.
How to do it:
- Lie on your back, bend your knees, and place feet hip-width apart.

How to do it:
- Start on hands and knees, tuck your toes, and lift your hips up and back.
- Keep your spine long and heels reaching toward the ground.
- Engage your core and breathe for 5–7 breaths.
Interesting Fact: Though commonly seen as a resting pose, Downward Dog actively strengthens the upper core and helps correct spinal misalignments over time.
5. Forearm Plank
Why it helps: A deeper core challenge than the traditional plank, putting more demand on the abdominal muscles.
How to do it:

- Keep your gaze slightly forward and neck long.
- Hold for 20–30 seconds.

How to do it:
- Begin in plank, shift weight onto your right hand.

- Keep your hips high and core engaged.
- Hold for 20–30 seconds per side.

- Move slowly, coordinating breath with movement.
- Repeat for 1–2 minutes.

Frequently Asked Questions (FAQs)
Can yoga really help build core strength?
Yes, yoga is highly effective for building core strength. Many yoga poses activate deep abdominal muscles, including the transverse abdominis and obliques, which are essential for stabilizing the spine and improving posture. Consistent practice can significantly improve both muscle tone and control.
How often should I practice these poses to see results?
For noticeable results in core strength and posture, aim to practice 4–5 times per week. Even 15–20 minutes daily can lead to improvements over time, especially when poses are held with proper alignment and engagement.
Do I need to be flexible to start these yoga poses?
Not at all. These poses can be modified to suit all flexibility levels. Yoga is about progress, not perfection. Props like blocks or straps can help beginners maintain proper form while gradually increasing flexibility.
Can I do these yoga poses if I have back pain?
Many of these poses, like Cat-Cow and Cobra Pose, are gentle on the spine and can actually help relieve mild back pain. However, if you have chronic or severe back issues, it’s best to consult a healthcare provider before starting any new exercise routine.
What time of day is best for practicing yoga for posture and core?
Morning practice can help energize the body and improve posture throughout the day. Evening sessions can release tension built up from long hours of sitting or standing. Choose a time when you can stay consistent and focused.
Is it okay to do core yoga every day?
Yes, daily yoga for core strength is safe as long as you listen to your body and avoid overstraining. Alternate between intense and restorative poses to allow recovery and maintain balance.
How long does it take to improve posture with yoga?
With consistent practice, some people notice better posture within a few weeks. Long-term improvements, like reduced slouching and spinal alignment, typically take 2–3 months of regular effort.
Are these poses suitable for beginners?
Most of the poses in this list are beginner-friendly or can be modified for different skill levels. Start with foundational poses like Plank, Cat-Cow, and Bridge Pose before progressing to more advanced positions like Warrior III or Side Plank.
Do I need any equipment for these poses?
You only need a yoga mat. Optional props like yoga blocks, straps, or a bolster can provide additional support, especially if you’re just beginning or have limited flexibility.
Can yoga replace traditional core workouts like crunches or planks?
Yoga complements traditional workouts and, in many cases, can replace them. It activates more stabilizing muscles, promotes balance, and includes the benefit of flexibility and posture correction — something most conventional core routines lack.
