The hollow body position is an isometric hold, often used as a standalone core exercise. However, when applied correctly, it can be the basis to develop some creative exercises involving the upper body.
Traditionally, the hollow body position involves laying on the ground with only your bum and lower back in contact with the floor, challenging the anterior aspects of your core for stability.
However, when adjusting for overhead movements, the lower back will also come up off of the ground, leaving your bum to be the only point of contact.
This position is what we will primarily be using as it doesn’t only challenge the anterior core, but the posterior musculature involved in stabilising the spine.
There’s also more scope to be creative when doing overhead movements, giving you more options to progress and keep yourself challenged!
