"It seems like about every week or two weeks we'll get a good breakthrough with something and move forward," Wieters said. "Then we'll have another week or two of trying to get to that next phase or feeling where we're trying to get it back to feeling as normal as possible as quick as possible.
"But it's all going well," said Wieters. "We keep getting closer to it."
Wieters admitted he won't know if he will be able to have a full Spring Training until he resumes throwing, which may not happen until November.
"For me, the big thing is, anytime we get to add new exercises and new strengthening things that kind of give us more optimism and gives us something else that we can work on."
Manager Buck Showalter recently noted that head athletic trainer Richie Bancells was "upbeat" about Wieters' progress, particularly the catcher's improved range of motion.
