Formmaster or similar deice

[TSchirm]

I am newly back to trad archery after about 10 years gone due to a minor non archery related shoulder injury.  My old recurve hurt my shoulder after the injury, but a lighter one I was recently able to get doesn't hurt to draw.  However, trying to shoot the heavier bow when it hurt has caused me to develop several form problems I need to overcome and change.  I know I need to use my back muscles more than I have, so I am wondering if the formmaster, or something like it, would be really helpful?  I am very budget limited right now due to a family health issue, so any suggestions are appreciated.

Here is the link to a thread from last year about making a Formaster.
I have a bunch of them for only a few dollars.
Good luck!
