Bruising San Francisco 49ers running back Carlos Hyde expects to be on the move a lot more in new head coach Chip Kelly’s offense.

To prepare for the up-tempo pace of Kelly’s system, Hyde is trying to shed 15 pounds this off-season and cut his playing weight down to 220 from 235. According to athletic trainer David Alexander, who’s training Hyde and other athletes at DBC Fitness in Miami, the ballcarrier is already under 230. Alexander, a respected trainer who works with several top-tier pro athletes, including LeBron James and Dwyane Wade, says he wants Hyde to build endurance for long, sustained drives.

“I’ve got his mind wrapped around being on the field for 10 plays straight,” Alexander told the Sacramento Bee.

In a series of videos recently posted to Alexander’s Instagram account, Hyde does appear slimmer. The running back moves fluidly through a series of multi-directional drills, weaving in and out of cones and jumping over obstacles. Here he is with teammate Bruce Ellington:

And here’s Hyde performing several single-leg drills on his own:

Hyde’s flashy footwork should be especially encouraging to 49ers fans, since it seems to indicate that he’s fully recovered from a stress fracture in his foot that shortened his 2015 season. The hope is that he will return to his form in Week 1 of that season, in which he ran for 168 yards on 26 carries, including two for touchdowns.
