Cubs pitcher Jake Arrieta revamped his offseason program, and he hopes the changes will pay off this season. 

Arrieta cut back on weight training in favor of Pilates. He does the yoga workouts six days a week, which will improve his range of motion and stamina. 

"A lot of guys are starting to get way from trying to jerk these heavy weights and throw all these heavy weights around," Arrieta said, per the Baltimore Sun. "Building strength is very important, but there are many ways to do that. That's why I got into Pilates because I can reduce the stress and impact in my joints while still being able to increase strength and flexibility, and it's going to pay dividends."

Arrieta also cut back on red meat and added a high concentration of fruits and vegetables, including kale juice. 

"The first thing you have to do is understand the nutrients your body needs," Arrieta said. "The best way to get those sources of nutrition is from vegetables, nuts, beans and things that aren't processed."

Arrieta has a 2-1 record with a 5.40 ERA this spring.
