Top 5 Transverse Abdominal Exercises for a Stronger Core in 2025

Achieving a powerful core requires targeting all of your abdominal muscles, including the often-overlooked transversus abdominis.

While many focus on the visible 'six-pack' rectus abdominis, the transversus abdominis lies deeper and plays a vital role in core stability and spinal support.

Strengthening this muscle not only enhances your core strength but also helps alleviate back pain and boosts overall functional movement.

Unfortunately, most traditional ab workouts neglect this crucial muscle. This article explores the anatomy and importance of the transversus abdominis and introduces five effective exercises to engage and fortify it.

Understanding the Transversus Abdominis Muscle

The transversus abdominis is the deepest abdominal muscle layer, situated beneath the internal and external obliques and rectus abdominis. It extends horizontally from ribs 7–12 down to the pelvis, acting like a natural corset around your midsection.

Its unique horizontal muscle fibers provide essential support and stabilization for your spine during daily activities and athletic movements.

This muscle also maintains abdominal wall tension and increases intra-abdominal pressure, supporting internal organs and aiding in functions such as forced expiration, childbirth, and elimination.

Key Point: The transversus abdominis acts as the body’s natural 'corset,' crucial for spinal stability and core strength.

Benefits of Strengthening the Transversus Abdominis

Physical therapist Marcy Crouch, PT, DPT, highlights the importance of this muscle as a primary core stabilizer that supports the spine, reduces back pain, improves pelvic floor function, and enhances posture.

Reduces Lower Back Pain

A strong transversus abdominis contributes to dynamic lumbar spine stabilization, working alongside muscles like the multifidus and pelvic floor to protect your back during movement.

Research shows that targeted exercises activating this muscle can alleviate lower back pain by improving spinal support.

However, consult your healthcare provider before starting new routines, especially if you have pre-existing conditions.

Decreases Injury Risk

Core strength, particularly in the transversus abdominis, safeguards your back during heavy lifts such as deadlifts and squats by encouraging proper bracing and spinal alignment.

Potentially Slims Waistline

Due to its corset-like function, strengthening the transversus abdominis may help create a slimmer waist appearance by pulling the abdomen inward.

While it does not create visible six-pack abs, which depend on low body fat, many fitness enthusiasts report improved waist definition through focused training of this muscle.

Summary: Strengthening the transversus abdominis enhances core stability, reduces back pain, lowers injury risk, and may contribute to a more defined waist.

How to Activate Your Transversus Abdominis

Engaging this deep muscle requires mindful practice. Physical therapist Marcy Crouch recommends exhaling while drawing in the lower abs and engaging the pelvic floor muscles, avoiding simply 'sucking in' the stomach.

To feel the contraction, place your fingers just inside your hip bones and practice the abdominal drawing-in maneuver (ADIM):

1. Lie on your back with knees bent and feet flat.
2. Place two fingers an inch inward and downward from the top of your hip bones.
3. Exhale slowly through your mouth while drawing in your lower abdomen and engaging pelvic floor muscles.
4. Hold the contraction for at least 10 seconds while breathing normally.

With consistent practice, engaging the transversus abdominis will become more natural during your workouts.

Tip: Focus on coordinated breathing and pelvic floor engagement to properly activate this deep core muscle.

Top 5 Exercises to Strengthen Your Transversus Abdominis

Incorporate these stabilization-focused exercises to effectively target and build your transversus abdominis:

1. Hollow Body Hold

1. Lie flat with arms extended overhead and legs together.
2. Engage your core, lift legs 12–18 inches, and raise shoulders off the ground, keeping your lower back pressed to the floor.
3. Hold for 15–30 seconds, maintaining a 'banana' shape with your body.

2. Dead Bug

1. Lie on your back with arms reaching up and knees bent at 90 degrees.
2. Slowly extend your left leg and lower your right arm without touching the floor.
3. Return to start and alternate sides for 30–60 seconds.

3. Toe Taps

1. Lie on your back with knees bent in tabletop position.
2. Engage your core and lower one foot to tap the floor, keeping your back flat.
3. Alternate sides for 30–60 seconds.

4. Bird-Dog

1. Start on all fours with a neutral spine.
2. Extend opposite arm and leg, hold for 2–3 seconds while engaging your core.
3. Alternate sides for 8–12 repetitions.

5. Plank

1. Assume a forearm plank position with body aligned and core tight.
2. Hold as long as possible while maintaining proper form and drawing in your abdominals.

Note: These exercises emphasize core stabilization over traditional crunching motions to effectively engage the transversus abdominis.

Conclusion

The transversus abdominis, your body's natural corset, is essential for spinal protection and core stability. Strengthening it can reduce back pain, lower injury risk, and potentially enhance waistline appearance.

Practice mindful engagement through breathing and pelvic floor activation, and incorporate stabilization exercises into your routine to maximize core strength.

Remember, a strong core starts from the inside out—don’t overlook your transversus abdominis in your fitness journey.
