This workout will also work if you are dealing with a weak or injured hand/wrist- You will need a mini band for sure!

Optional to use weights (recommended)
TRX (highly recommended)
And or a band with Handles with a door anchor or something you can anchor it for pull work.

Typically I would sell things like this, so thank you for asking me first!
Here is a link you could purchase one- or at your local Canadian Tire, or walmart too.
