Welcome to part two of my three stage approach to core stability. By now you should have a good grasp on Diaphragmatic breathing and establishing a Zone of Apposition (ZOA). Next, I like to challenge the ZOA and thus lower back stabilisation via the following two exercises:
- The Bird dog row (anti extension)
- The Dead bug with short foam roller (anti extension)
The Bird dog and Bird dog row
A google search of the term ‘Bird dog’ returned the following definitions:
- A gun dog trained to retrieve birds
- A talent scout
Oddly enough an image search of the term returned numerous images, such as the one on the left ( The internet wins again !) I mean is it a Bird Dog or a Dog Bird?! Anyway, moving on..
The Bird Dog can be considered to be an anti extension based core stability drill. Meaning the whole purpose is to avoid excessively arching the lumbar spine and losing the ZOA!!
The BD row involves something known a the Posterior Oblique Sling System. Just think of it as being a connection between one side of the trunk and the opposite side hip, as depicted in the image below.
This image clearly shows that the left Latissimus Dorsi and the left thoracic-lumbar fascia muscle will work with right Gluteus Maximus and vice versa, effectively connecting one shoulder with the opposite leg. An efficient function of this sling is required for a stable pelvis during gait. The video below from Tony Gentilcore shows how to perform the bird dog row using a kettlebell:
The Dead bug with short foam roller
The Dead bug is an anti-extension core stability drill performed on your back. The idea is to stabilise the lower back by creating a ZOA in a similar fashion to the BD. As shown by Tony Gentilcore again below:
The above version is a fantastic exericse. However, in the past i have found that beginner clients struggle to keep the two middle limbs stationary. It is usually a coordination issue but can also be a sign of limited strength of the hip flexor. I have found the Dead bug with short foam roller is a great alternative as it allows for more proximal stability, by virtue of squeezing the roller between the same side arm and leg. See my IG post below for a demonstration:
Both the BD and DB exercises allows for correct integration of proximal stability and distal movement, meaning a stiff trunk musculature will allow for more efficient movement of the limbs.
I hope this has given you a better insight into the Birddog row, Deadbug with a short foam roller and how they are the next logical step for beginners after they have learnt how to establish a ZOA. In the third and final installment I’ll touch upon lateral stability and anti rotation exercises and how they relate to multiplanar core training.
