The hollow hold is an isometric core strengthening exercise that can help target and strengthen the deep abdominal muscles, including the transverse abdominis, rectus abdominis, and obliques.

Hollow Hold – An effective exercise for working and strengthening your core muscles

Hollow Hold – Targeted Muscles

The hollow hold principally targets the muscles in the core region. These include:

  • Transverse Abdominis
    The transverse abdominis is the deepest layer of abdominal muscles. It wraps around the sides and front of the abdomen. It helps stabilize and compress the abdominal contents.
    Hollow holds activate and strengthen the muscle to help build the core muscles and keep it stable.
  • Rectus Abdominis
    The rectus abdominis, aka the “six-pack” muscle, runs vertically down the front of the abdomen. It helps with spinal flexion or the forward bending of the spine.
    Hollow holds engage the rectus abdominis to help maintain the position and stabilize the trunk.
  • Internal and External Obliques
    The internal and external obliques are on the sides of the abdomen. They assist with trunk rotation and side bending.
    You activate the muscles during the hollow hold to help stabilize the body and maintain the “hollow” position.
  • Deep Stabilizing Muscles
    In addition to the above, hollow hold engages various deep stabilizing muscles, including the multifidus, erector spinae, and pelvic floor muscles.
    The muscles help to stabilize and support the spine, leading to proper posture and alignment.

The primary focus of the hollow hold is on the core muscles, but the exercise also engages and strengthens other supportive muscles. That can help to improve stability, posture, and functional fitness.

  • Hip Flexors
    The hip flexors help to lift the legs off the floor during the hollow hold.
  • Lower Back Muscles
    The lower back muscles help to stabilize the spine and prevent excessive arching.
  • Shoulders and Upper Back
    The shoulders and upper back muscles, including the delts, traps, and rhomboids, help to lift the shoulders off the floor and keep the upper body stable.

Hollow Hold – The Exercise

The hollow hold is a bodyweight exercise that requires no equipment. But an exercise mat can keep you comfortable during the movement

Steps to follow

  • Lie flat on your back on a mat or the floor.
  • Extend your legs fully and stretch your arms overhead.
  • Draw your belly button in towards your spine to engage your core. The action helps activate the deep abdominal muscles.
  • Press your lower back downward, ensuring no arch or space between your lower back and the floor. That will help maintain spinal alignment and prevent unnecessary strain on the lower back.
  • Lift your shoulders off the floor, maintaining a slight chin tuck to avoid straining the neck. Your head and neck should be in line with your spine.
  • Simultaneously lift your legs off the floor, keeping them straight and together. Aim to make a 45-degree angle between your legs and the floor.
  • Maintain a “hollow” position by creating a slight C-curve with your body. Imagine flattening your lower back against the floor while simultaneously reaching your arms towards your feet and extending your legs away from your torso.
  • Focus on breathing steadily throughout the exercise. Inhale deeply through your nose, and exhale through your mouth.
  • Hold the “hollow” position for 20 to 30 seconds, or as long as possible.

Tips

  • Avoid arching your lower back or lifting it off the floor.
  • Keep your core engaged throughout the exercise by drawing your belly button towards your spine.
  • Lift your shoulders and legs simultaneously, maintaining a slight chin tuck.
  • Maintain a “hollow” position by flattening your lower back, reaching your arms towards your feet, and extending your legs away from your torso.
  • Breathe deeply and rhythmically.

Hollow Hold common mistakes

As with all exercises, it is vital to get the form correct. That will help you to maximize the benefits.

Below are some common mistakes to guard against when doing hollow body hold exercises. Making these errors can take you off course or negate the effects of your efforts.

  • Arching your Lower Back
    Allowing your lower back to arch or lifting it off the floor during the hollow hold is one of the common mistakes. Doing so will take the tension away from the core. It can also strain the lower back.
    Focus on flattening your lower back against the floor and engage your core to maintain a stable, hollow position throughout the exercise.
  • Lifting your Legs Too High or Low
    Raising the legs too high or too low can compromise the position and effectiveness of the hollow hold.
    Ideally, your legs should be at a 45-degree angle with the floor. Do not lift them too high, as it can strain the hip flexors, or too low, as that reduces the challenge for the core muscles.
  • Allowing your Shoulders to Collapse
    Do not allow the shoulders to collapse or hunch forward. That can reduce the engagement of the core muscles and strain your neck and shoulders.
    Keep your shoulders off the floor and maintain upper body stability during the hollow hold.
  • Holding your Breath
    Holding your breath or breathing shallowly during the hollow hold can limit the engagement of the core and increase tension in the body.
    Focus on breathing deeply and rhythmically throughout.
    Inhale through the nose and exhale via the mouth, allowing your breath to flow naturally.
  • Lack of Proper Core Engagement
    Not engaging the core muscles is another common mistake
    For best results, draw your belly button towards your spine, engage the deep abdominal muscles, and maintain tension throughout your midsection. That will ensure you’re effectively targeting the intended muscles and maximizing the benefits of the exercise.
  • Overstraining or Overexertion
    Ensure you listen to your body. Do not overstrain or overexert yourself during the hollow hold.
    Start with a comfortable duration and intensity and gradually increase the challenge.

You can optimize the effectiveness of the hollow hold and minimize the risk of injury by being mindful of these common mistakes.

Always consult a fitness professional for guidance and support if you have doubts or concerns.

Hollow Hold Benefits

Incorporating hollow hold into your training regimen can give you several benefits to help boost your fitness and well-being.

Core Strength

The hollow holds target the deep abdominal muscles and are great exercises for developing core strength.

Incorporating the exercise into your training can help strengthen and stabilize your core muscles.

That can help you to maintain proper posture, support your spine, and improve overall functional strength.

Improved Stability and Balance

The hollow hold requires you to engage your core muscles and lift your shoulders and legs off the floor simultaneously.

The exercise challenges your balance and improves your body’s stability.

That can enhance your ability to control your body’s movements in various activities.

Postural Alignment

Hollow holds promote proper spinal alignment and posture.

You focus on flattening your lower back against the floor and keeping your core engaged during the exercise.

That helps counteract the effects of prolonged sitting and poor posture, leading to better alignment and reducing the risk of back pain or injuries.

Functional Fitness

The strength and stability developed through hollow holds can translate into improved performance in daily activities and sports.

You need a strong core in almost all movements, whether lifting objects, bending, twisting, or participating in athletic endeavors.

Strengthening your core with hollow holds can enhance functional fitness and make it less challenging for your body to function.

Abdominal Muscle Definition

Including hollow holds in your fitness routine can help tone and strengthen your abdominal muscles.

The increased muscle tone from hollow holds can contribute to the improved definition and a more sculpted appearance in your midsection.

Programming suggestions for hollow holds

Below are some programming suggestions for hollow holds to consider

Frequency

Aim to include hollow holds 2-3 times in your weekly routine.
That frequency allows for sufficient rest and recovery between sessions while providing regular stimulus for core strength development.

Duration

Newbies should start with shorter hold times, such as 20-30 seconds.
Gradually increase the duration of your holds as you gain strength and stability.
Aim for 45-60 seconds as a target to work towards.
However, note that it is better to prioritize quality over quantity and focus on shorter, controlled holds.

Sets and Repetitions

Perform 2-3 sets of hollow holds per session. Newbies can start with one if necessary. Remember to take short breaks between sets to recover and maintain proper form.

Progression

Progress the exercise to continue challenging your core muscles as you become stronger and more proficient with the hollow hold.

You can increase the difficulty by incorporating variations such as leg lifts, arm reaches, or hollow rocks.

Additionally, you can add resistance by holding a weight against your chest during the hold or using ankle weights.

Integration with Other Exercises

Consider combining hollow holds with other exercises to target the core from different angles.
Planks, Russian twists, and bicycle crunches are some examples.

The variety can help enhance core strength and stability.

Warm-up and Cool-down

Warm your body with light cardiovascular activity and dynamic stretches before performing hollow holds.
That can help increase blood flow, loosen up the muscles, and prepare your body for exercise.

Do static stretches or foam rolling to cool down and promote muscle recovery after completing your hollow hold workout.
