Welcome Back! This nice thing about SP is you get as many do-overs as you personally need, and eventually it sticks! This is either my 3rd or 4th time here.
Since you mentioned in a wheelchair, look in the articles & videos section under Lifestyle Centers and you will find a page for those that are differently abled which will include seated exercises and other tips just for you.
A goal of consistent tracking is an excellent start! I know about scales. Used to have an electronic one that topped out at 330 and after that it just said "E"...and yes I was an "E" at one time.
I've added you as a Spark Friend so that I can help celebrate your success.
