G'day mate and welcome to the forum. My very quick advice to you right now is as follows: do not follow any type of structured program, be it weight resistance or aerobic. What you need right this minute is to get the ticks and not the crosses. By that I mean you need to get the job (whatever it is) completed successfully. So whether you decide to open your front door and go for a walk around the block, or lift some very light weight with good form, it matters not. What matters right now (for the fist week or two), is for you to gradually get yourself moving again, especially with the 120kg you're currently carrying. So easy does it, and slide into it instead of break into it. That is all for now.
All the best.
