Well not quite
Firstly I would have to say dont do anything post surgery/post rad until someone qualified
gives the go ahead - its too much of a risk to force things
So cheap exercise you can do at home ? - yes
Actually my recent experiances with.....sugar free gum... has worked a treat
Basically chewing exercises with gum when in the car/on the bus/when walking
once a day - helps refreash the quiet side (by making the rest move a bit more)
I have found better, and stronger, vocal clarity
improved carry, and pronounciation (sadley the spellling ...is no better)
just by this simple exercise
Be clear on this : I dont want you all to become rap artists
or buy hoodies, or leather jackets - there is enough gang violence
already in the world....
a simple 99 cents a day exercise seems to make a big difference
(dont go picking fights now)
Good luck
and
Best Regards
Tony
