As the saying goes, the baseball season is a marathon, not a sprint.

But to get through that marathon—a long and grueling run of 162 games, barely any off days, and day-night doubleheaders—baseball players need to be in prime shape. With so much time dedicated to actually playing baseball during the season, players need to make the most of their offseason, which means spending hours in the gym crushing their workouts.

Want an example? Check out what Washington Nationals star and 2015 NL MVP Bryce Harper has been doing to get ready for the season:

Some players may have changed teams this winter, but just like Harper, stars all over the majors have been getting in the gym this offseason.

Addison Russell, shortstop of the World Series champion Chicago Cubs, has been getting in some resistance drills (check out his 7 essential exercises from his conversation with Men's Fitness). Giancarlo Stanton of the Miami Marlins does curls with massive dumbbells. Los Angeles Angels superstar Mike Trout does sled work. Point is, there is no "off" switch in the offseason, and these guys prove it.

Here are 30 players who have been absolutely crushing it in the gym this offseason:
