5 Multifidus Exercises for a Strong & Stable Lumbar Spine

Exercises to Prevent Low Back Pain and Train an Under-Appreciated Muscle

While the multifidus is a relatively small muscle, it’s critical for spine stability and these effective multifidus exercises can prevent and rehabilitate low back pain.

While the multifidus is a relatively small muscle, it’s critical for spine stability and these effective multifidus exercises can prevent and rehabilitate low back pain.

What is the Multifidus?

The multifidus is basically a bilateral series of muscles that are attached to the spine. Think of the vertebrae as the rungs and the multifidus as the rails on a ladder.

Although it was once considered a relatively unimportant muscle because of its small size, researchers have since discovered that its unique design makes it one of the strongest and most important muscles in maintaining a healthy back.

The multifidus looks like a long, thin pencil stuffed with millions of little fibers. These fibers are further arranged within a rod-like structure and are stiffer than any other fibers in the human body. [1]

Anatomy of the Multifidus

The multifidus is one of the four muscles that make up your body’s inner core. The other three muscles of the inner core are:

  • Transversus abdominis
  • Diaphragm
  • Pelvic floor muscles

This muscle is composed of several fleshy and tendinous fasciculi (it means: a small bundle), which fills the grooves on each side of the spinous processes of each vertebra, and extends from the sacrum to the axis.

The multifidus is deeply situated in the spine and spans 2 to 4 vertebrae.  Its main action is to stabilize each joint at the segmental level. This creates stiffness and gives you a solid platform from which to generate movement and it also prevents excessive wear of the passive vertebral structures like the discs and ligaments. [2]

One big myth is the role of the Transverse Abdominis in providing local segmental stability – it doesn’t, and is more a global stabilizer via the mechanism of intra-abdominal pressure.

The Multifidus and Proprioception

The Multifidus also has an unusually high number of muscle spindles. [3] Muscle spindles are sensory receptors in your muscles that can detect changes in the length of a muscle and signal this information to your central nervous system. The central nervous system then uses this information to figure out the current position of the body.

This is called proprioception: the ability of your body to sense where all of its parts are in space. Proprioception is how you can touch your fingers behind your back, and you can touch your nose when your eyes are closed.

Low Back Pain and the Multifidus

It used to be believed that the spine by itself was very stable and strong, but recent studies have shown that the spine, even though it’s very mobile, is also very fragile.

In fact, it can only support about 20 pounds of weight before collapsing. Thus, muscular support is critically important for spine stability. [4] This clearly shows how muscle weakness in general and specifically a weak or dysfunctional multifidus muscle can cause low back problems.

Research has also demonstrated that multifidus atrophy will frequently accompany low back pain. [5] Whether the chicken or the egg came first hasn’t been sorted out yet, researchers have demonstrated that performing multifidus exercises to strengthen this muscle will in many cases relieve low back pain.  The same research study found that rehabilitating the multifidus will reduce the odds of a recurrence. [6]

Multifidus Exercises Are a Game Changer

Learning how to train the multifidus was a game-changer for my back. When I first started doing the Birddog, I was so shaky I felt like I was having a seizure, but I quickly improved with daily training.

Then, when I started adding the more advanced exercises we’re about to go through, I noticed a significant jump in my power when throwing punches, taking shots in hockey and every other sport that requires swinging of a club, racket or bat.

The reason why is because the transverse plane of motion is critical to power in most sports and is also the plane of motion least trained in the gym and the one that must be trained to effectively target the multifidus.

So adding these exercises will not only help prevent and rehab low back pain, they’ll also improve your performance for any sport.

Over-reliance on core stability exercises that only work in the sagittal plane of motion i.e. crunches and planks, do not effectively train the multifidus. The multifidus is activated most when stability in the transverse plane of motion is required.

Many studies have shown that the multifidus muscle is atrophic in patients with back pain.  The good news is we can learn to turn the muscle back on and strengthen it to protect our back in the future.

Sometimes the multifidus can get a little a little fibrotic and tight when it is weak.  I love to loosen the multifidus prior to activating and strengthening the muscle using a peanut roller.

You can make your own peanut by putting two tennis balls in a sock.  

5 Great Multifidus Exercises for Spine Strength

The Birddog

While this exercise has a funny name, and doesn’t look like it has anything to do with a dog; it’s a highly effective way to activate the multifidus and will encourage lumbar spine stability.  There are a few variations, but we’re going to stick to the beginner’s version.

To perform the bird dog:
multifidus exercises the bird dog

  • First get on your hands and knees.
  • Next, position your shoulders directly over your wrists while pointing your fingers forward and keep your hips over your knees.
  • Then engage your abdominal muscles and lift your right leg straight to the rear while keeping your hips level. As soon as you feel stable, lift your left arm forward.
  • Finally, stretch your body out. Make sure you keep your neck in line with your spine. Hold this position for a few seconds before returning to the starting position.

1-Arm Pushup

This is the classic calisthenic move taken to the next level.  I don’t expect many of you reading this to drop and start pumping out perfect 1-arm pushups, so here are a series of progressions for all strength levels:
multifidus exercises 1-Arm Pushup

  • 1-arm wall pushup: like the name says we’re going to use the wall as our working surface.  Start by standing in front of a wall, next place one arm straight in front of you and firmly pressed against the wall and keep your free hand by your side. Now bend your elbow and drop your body toward the wall. Complete the movement by pushing back up.

multifidus exercises 1-arm table pushup

  • 1-arm table pushup: Same technique as when doing a wall pushup.  Place one hand on a table keeping the elbow straight and keep the free arm by your side.  Bend your elbow until your chest is close to the table edge and push back up.  Place your legs farther back for greater resistance, closer for less.

  • 1 arm pushup progression:  the first progression starts from the standard pushup position, you’re going to slide one hand forward until your chest touches the ground. Finish the movement by sliding that hand back under your shoulder.  This will increase the resistance on your working arm and teach you the necessary balance.
  • For the next progression, you’ll need a ball.  Start from the standard pushup position but place one hand on a soccer or basketball.  The elevation and the instability of the ball will force you to adapt by relying much more on one side, developing the strength that will make a genuine 1 arm pushup possible.
  • The last progression is hard so try to perform it when you’re fresh.  Begin in a standard pushup with your arms straight, now drop until you’re half way to the ground – and hold it. Finally, slowly slide one hand to the side until your arm is straight and then slide it back for a sick level of isometric tension on your stationary side.

1-Arm Row

The 1-arm row is a fantastic all around back exercise and is extremely useful for stimulating the multifidus. Here are three effective variations you can use.

First is the supported 1-arm row:

Find a weight bench and place a dumbbell on each side of it.

  • Place your right leg on top of the bench’s far end, bend your torso forward from your waist until the upper body is parallel to the floor, and now place your right hand on the opposite end of the bench for support
  • Pick the dumbbell up from the floor with your left hand and hold the weight while maintaining a straight lower back.
  • Pull the dumbbell straight up to the side of your chest while keeping your upper arm close to your side and the torso stationary.
  • Lower the resistance straight down to the starting position. Breathe in as you perform this step.

The next variation is the 1-arm cable row:

  • Start the standing one-arm cable row by attaching a single handle to a low pulley cable.
  • Standing around 3 feet from the cable machine, grasp the handle with one hand, arm straight.
  • Pull the handle toward you while keeping the knees slightly bent and your arm close to your side. You can put your free hand on your leg for stability.
  • Slowly lower the weight back down.

Last you can do the bent over 1-arm row:  This is just a 1-arm dumbbell row without using a bench for support. It not only works the multifidus but also the whole core as you tense your waist to stabilize your upper body.

  • Start by standing with feet shoulder-width apart, with the dumbbell in front of you
  • Next bending at the waist into a hinge movement, grasp the weight with one hand and pull it up into a row
  • Slowly drop the weight back to the floor

T-Lateral Ball Roll

This is a real core crusher; the T-lateral ball roll will attack almost every torso muscle in your body.

  • Start by lying on your back on a balance ball so that your upper back is firmly on the ball.
  • Raise your hips to form a straight line from your knees to your shoulders.
  • Hold your arms straight out from your sides.
  • Without letting your hips or arms sag, roll across the balance ball as far as you can, take small steps sideways with your feet, you should only be able to go a few inches before running the risk of falling off.
  • Now reverse direction and roll as far as you can to the other side.
