I'm still very much of a newbie to weight training. Because of an overuse
incident when I first started training, my trainer is a little wary of
having me work w/ heavy weights for now, so she's been having me work with
lighter weights/lower % of body weight for body weight exercises, but
making the exercises more challenging by introducing an instability
element, eg standing on a mat or 1 leg, lying on a ball, etc.
I can see where these are helpful in recruiting some of the smaller, less
used muscle so that I'm eventually at a point where I can start using
heavier weights and they're certainly giving my balance skills a workout.
But, I was wondering, do these sort of exercises in themselves encourage
appreciable muscle growth? Or do they just get the body in better shape to
start building muscle later?
IMO, unless you have a pathology balance boards and balls are about as
inefficient a way of exercising as there is. Sure, they are trendy and
allow trainers to demonstrate their knowledge. And that is about the
extent of their usefulness.
There is some inherent instability in any free weight exercise which
promotes recruitment of stabilizers. To introduce an unstable platform
at the closed end of the kinetic chain is completely unnecessary except
in the case where due to injury or pathology there is a pervasive reason
to do so.
I do like the idea of assymetrical loading, but prefer to do so by
lifting with one arm or in a split stance rather than stand on one leg.
I start people off with bodyweight exercises and ane-armed dumbbell
lifting, which I think can be excellent core training if done properly.
So doing something like the 5 tibetan rites (do a search using that name
if you aren't familiar with them) for a dynamic warm-up, doing hindu
squats to a tabata interval and then adding one-armed exercises like
overhead squats, presses, snatches, windmills, etc. works very well IMO.
Of course, the idea of these exercises is to promote strength and
movement more so than simply build muscle. I prefer function to
appearance. So they promote a large ROM throughtout all the joints,
joint health itself and strength through a full ROM in complex exercises.
IMO beats the living daylights out of the current trends in 'core'
training and instability training.
