The San Francisco 49ers quarterback opens up about his rise from unheralded recruit to NFL elite for millions of high school athletes nationwide.

Colin Kaepernick started the 2014 NFL season strong with two touchdown passes and a victory over the Dallas Cowboys in Week 1, adding another TD pass in a solid effort against the Chicago Bears in Week 2.

STACK Magazine kicks off the 2014-2015 school year on an equally powerful note, unveiling a Back to School issue packed with helpful info for student-athletes, including an interview with and and exclusive look inside the workout of the San Francisco 49ers’ quarterback.

As the featured cover athlete for STACK’s Back to School issue, Kaepernick shares training tips and advice that can help any athlete become stronger, faster, and more agile. Kap gets real about his long and unexpected road to the Super Bowl, and—in a six-page feature packed with original photography—he gives readers a firsthand look at the work he’s putting in to stay at the top of the league. Read the full cover feature online.

Spoiler alert: the workout is intense. Kap says that’s by design.

“In my mind, there are still a lot better athletes out there than me. There are people who are a lot smarter than me, or throw the ball better than me,” Kaepernick said. “Even If I am not as talented as someone, even if I am not as good or as smart, I can outwork them.”

STACK’s story about Kaepernick is accompanied by an in-depth video series on STACK.com, demonstrating the exercises in his workout routine and relating how Kap overcame a challenging high school recruiting experience. Those clips, which join the library of thousands of training and nutrition videos on STACK.com, are available at STACK.com/Kaepernick.

Kaepernick’s strong work ethic and cutting-edge approach to training fit perfectly with STACK’s mission to help athletes everywhere get better.

“Colin is an inspiration, and his success is proof that young athletes can achieve their dreams,” said STACK executive editor Brian Sabin, who spent the day with Kaepernick as part of the project. “His workout was one of the most challenging we’ve seen, so it’s no surprise that Colin is one of the best conditioned athletes in all of sports.”

In addition to Kaepernick, the Back to School 2014 issue includes training tips from three-time Olympian Lolo Jones and Todd Durkin, trainer to Drew Brees, Blake Griffin and other elite athletes.
