I do think you should consult with a physical therapist. That said, I think machines are going to help you a lot.
With inured wrists you could do a lot with a cable machine and a wrist attachment. You could use a pec dec machine and your forearms to work your chest.
For legs you could try leg curls and leg extensions if you can lift far enough away from your ankle.
“General athleticism and fitness” is not a defined goal.
How long have you been doing his programs and in that time, what have you accomplished?
