Lauded for his work ethic and attention to detail last season as a true freshman, SEC Heisman candidate Nick Chubb is using spring break to further develop physically, transforming his body into a durable, ball-carrying machine prior to spring practice.

Courtesy of 247Sports’ Rusty Mansell, who lives in Georgia and attended Chubb’s workouts at Cedartown High in Cedartown, Ga., he has provided these gems on Vine of the Georgia running back’s regimen this week:

Chubb rushed for 1,547 yards last season and scored 16 total touchdowns despite not becoming Georgia’s primary running back until the Bulldogs’ sixth game.

He posted eight 100-yard games including the second-highest single-game total in school history (266) in the Belk Bowl against Louisville.
