Chapman, 28, has missed matches at the business end of each of the Cats' last three campaigns.
Surgery effectively took care of the groin issues, but he underwent contentious blood injection therapy ahead of the 2009 grand final, which allowed him to boot three goals and claim the Norm Smith Medal.
The procedure which saw some of his blood drained, spun to increase oxygen content and then injected back into the muscle has since been banned by the World Anti-Doping Agency.
But even without the controversial therapy to call upon, Chapman is confident he can power, instead of limp, into this year's finals series thanks mainly to the arrival of former English rugby team physiotherapist, Mike Snelling.
"If you had have asked me last year I would have thought [the hamstring problems were] going to go on forever, but I see light at the end of the tunnel now," Chapman told geelongcats.com.au. "I don’t know how we managed to get [Snelling] but he has been fantastic for me. He really knows his stuff, especially regarding hamstrings. It was great to have a different way of looking at things.
"There is a lot of sports science in it. He put on a strong program for me over pre-season [and] he is forever on to me… to do those extra things.
"So I have done a lot more work on (the hamstrings) this year, hopefully this year can be the one when I can get over it."
Chapman also credits the cub's newly-opened training facilities for allowing him to make the most of his time spent in the gym.
"For the past few years we have been in a little tin shed, near the smaller swimming pool," he said. "You were doing your weights on top of each other, or doing it in little groups. We were still jumping in rubbish bins full of ice. It may surprise people that the reigning premiers were still jumping in bins of ice.
"It is a much nicer way to do recovery now. Blokes are even rocking up at night to do a bit of extra recovery.
"There were no complaints before and the staff were fantastic but it has just made it a lot easier having these facilities."
