Why core strength training relies on instability

my_first_pilates_workout_watchdogWhether using balls, BOSUs or balance discs, athletic trainers and personal trainers alike know that instability is the key to training the core.

The deep muscles of the core are involuntary muscles that engage automatically when subjected to instability.  In other words, one can go through a lengthy traditional workout involving elaborate weight machines, free weights, etc., but unless instability is introduced into the training regime, the core musculature may not be targeted at all.

Given the right cues by a qualified trainer, one can learn to activate his/her core musculature in traditional abdominal work.  For instance, most Pilates mat exercises do not involve instability (unless you’re doing Pilates on a boat), but you can activate the core by deliberately engaging the muscles of the pelvic floor.  (Think “kegel exercises” if you are not familiar with the term “pelvic floor muscles.”)  Activating the pelvic floor triggers the deepest abdominal muscle, the transversus abdominis, to fire.

Keep checking back for more information on this unique muscle and the exercises that strengthen it!  In the meantime, if you just can’t wait, try our “Get on the Ball“, “Meet your Core” and “Small Ball Toning Workouts” on www.ultimatepilatesworkouts.com as all provide ways to introduce instability into your workout and target your multifidus!

    Hi,

    Great posting!!
    I am a trainer that develops core training equipment in line with the ‘instability’ methodology (called Akrowheels if you are interested). I’ve consulted with several Pilates instructors and I agree with all your points above. Particularly in that instability training recruits more muscles, in a smarter way and in less time.
    Anyway keep up the great work and distributing the important message about core training with Pilates!
