Tom Barrass says he has trimmed down after feeling overweight towards the end of his breakout 2016 season.
"I've leaned up a little bit from last year. I was pretty fat towards the back end of the year," Barrass said.
"That's just the nature of the season, with carb-loading you tend to stack on a few (kilos).
"But I'm feeling a bit leaner and a bit lighter this pre-season, but I don't feel like I've lost too much strength."
Barrass was in West Coast's best side from round 12 onwards and looks set to form a combination with fellow key defensive revelation Jeremy McGovern for years to come.
"I suppose last year was a little bit surprising, but at the same time I felt that I really got on top of my preparation last year and even through the WAFL I was playing good footy," Barrass said.
"When I got into the side and I was able to start stringing some games together, it was a little bit surprising, but at the same time it's just a game of football at a higher level.
"I was confident that I would be able to continue my form."
