How to cure shoulder problems

How to cure shoulder problems (Trust me this will do it 90% of the time)
With a large towel or broomstick I want you to hold it with straight arms for the entire
time of what i describe in the following movement--a large "rolled up like a rope" beach
towel works good but honestly a longer broomstick (without the bristles) works best in
my opinion. Start out with it with a really wide grip (with straight arms) in front of you
(on your quads) and with straight arms bring it up and overhead and then down and back
to the middle of your back--STRAIGHT ARMS ALL THE WAY--this is going to be
very difficult and hard the first couple times out and then will be "old hat" with time----
and its going to be painful in a stretching pump kind of way---i want 50 reps each time
you do this--one repetition is from in front of your face (all with straight arms) to up
overhead and back, and then down all the way to the middle of your back and then back
up overhead to in front of your face again (again all with straight arms)--the important
part of the movement is the area overhead that is really tight--do all of this
carefully/slowly---dont just whip it over and back---if your hand is slipping off the
broomstick even with the widest grip, or you cant bring your arms over straight and the
start bending on you, you have some serious shoulder inflexibility and need to work this
hard and get up to speed (or you could just need a longer broomstick too)--again do all of
these revolutions controlled and carefully--push into the stretch as you go along toward
the 50 revolutions, your chest will be pushing outward and your shoulders rolling back--
your shoulders are going to blow up with so much blood its going to be incredibly
painfull pumpwise--Do this once a day at nite as many times a week as you can---
sometimes I have people do it every single day---but every time you do it try to move
your grip inward (thats the key)----its going to be very hard to do but try your best to
move your grip inward for the next 2-4 weeks and your range of motion with shoulders
will increase dramatically and any impingement and the majority of other problems
should be gone in 2 weeks--also try to move your grip in as you are doing the 50
revolutions--start off with a stretching but relatively easy 10 to warm up some, then try to
move your grip in even by a centimeter if you can for the next 20 revolutions and then at
30 try to move the grip in another centimeter--really try to push what you can do
stretchwise once your warmed up here--trust me this sounds easy but your going to be
muttering "fuck you dante" after you get to your 25th revolution--Ive cured too many
shoulder problems with this simple movement now its pretty ridiculous, and this and a
menthol rub applied liberally daily and before sleep has cured alot of shoulder/bicepital
tendonitis in trainees ---Heres a pic attached to this post so you can get an idea (thanks to
a trainee of mine who cured his shoulders with this)--but remember the broomstick goes
overhead and all the way back to the middle of the back (he just drew the start of the
movement when you begin)
