I have had both shoulders replaced, about a year and a half apart, with the most recent one about 3 years ago.
Both of my shoulder replacements were the standard rather than the reverse prosthetic.
My first piece of advice is to have the two surgeries at least one year apart. The aftermath of the surgery is a shoulder that is pretty traumatized and having one arm that sort of works can be a blessing.
After the surgery, ice and pain medications are both necessary.
Then, expert and focused physical therapy is a must.
Once your shoulder is "functional" and you are released from physical therapy, then it is time to get in the gym and build "a fortress of muscle" around the joint.
Pressing motions like a bench press are going to be very limited because of the damage that those motions can do to the implant. Pulling motions like the lat pull down and the row are almost unlimited. Please be aware that you will be building your muscles up from next to nothing, so take your time.
The draw shoulder heals a lot faster than the bow-arm shoulder. This is due to the shoulder's ability to handle compression being a very slow process to rebuild.
I am now using a bow that is 45# at my draw length, and I am doing so comfortably.
Ron LaClair had a reverse shoulder replacement, and he is shooting again.
Later today I will post a link to my TradGang shoulder replacement thread so you can benchmark the recovery process.
Be aware that you can recover and be happy with your new shoulders. Just do your exercises and be patient.
