Tummy tuck - getting back on the trainer

So I’m 3 weeks into recovery after a tummy tuck, also 3 weeks off the trainer.

Seems I can get back to light training this week, anyone have any experience with getting back to a plan and the trainer after this kind of surgery? My usual avg 6 week TSS was 7-800.
I setup SSBMVI at week 4 for now.
Going to try some 50% FTP rides first.
