Gunnar Henderson's Secret to SPEED: How He Got FASTER This Offseason! (2026)

Get ready to dive into the world of MLB speedsters! Gunnar Henderson, a name that's becoming synonymous with lightning-fast moves, has embarked on a journey to enhance his already impressive speed. But here's where it gets intriguing...

In a warehouse in Pelham, Alabama, a unique training session unfolded. Gunnar Henderson, with his towering 6-foot-3 frame, lunged between cones, guided by alternating lights. It was a dizzying display of agility, but beneath it lay a deeper purpose.

The bands and sleds, initially restricting, became tools of transformation. Gunnar was relearning the art of running, a skill he realized had eluded him since his early days of jogging.

Enter Cal Tinsley, owner and trainer at Tinsley Performance. Together, they set a goal: to add speed to Henderson's arsenal. And it's not just about the raw speed; it's about understanding the mechanics of running.

"You're told to run faster, move your feet quicker, but that can be counterproductive," Tinsley explains. And he's right! Think of Scooby-Doo's iconic wheel-spinning (or paw-spinning) before he takes off.

Gunnar, though not a cartoon dog, had a similar habit. He rose to his full height too quickly when sprinting, creating more vertical force than horizontal, which slowed him down.

"The first few yards are about power and horizontal force," Tinsley says. "When that force becomes vertical, you take unnecessary steps and lose momentum."

So, they focused on the cone drill, the bands, and the sled. Gunnar learned to keep low, making his shins parallel to the ground. This simple adjustment improved his first three steps, the most crucial for reaching the ball.

"Those first steps are make-or-break," Tinsley adds. "We worked on his 10-yard split, and the results were impressive."

Henderson's size is an advantage, especially at the plate, where his powerful build shines. But he understood that his size could hinder quick movements at shortstop or on the bases.

"I need to stay agile and maintain my speed," Henderson says. And he's doing just that!

Even without specialized training, Henderson proved himself as a base-stealing threat last season, swiping 30 bags. But he wanted more.

Stealing bases is an art. It's not just about speed; it's about reading pitchers, executing perfect slides, and reacting swiftly.

Tinsley and Henderson measured his 10-yard split, and the results were eye-opening. Shaving off mere fractions of a second can make a massive difference.

"A drop of five-hundredths of a second is huge," Tinsley explains. "Henderson is an explosive athlete, and with some adjustments, he's becoming even faster."

Through intense drills, Henderson learned to keep his body lower, channeling his power horizontally. The results? Significant time drops!

"His average 10-yard split improved from 1.53 to the mid-1.40s," Tinsley reveals. "That's elite!"

To put it in perspective, a 0.1-second improvement over 90 feet could mean a time of 3.2 seconds or even sub-3.1 seconds from first to second base.

At Tinsley Performance, Henderson trained alongside Tyler Tolbert, a speedy utility man for the Kansas City Royals. Henderson kept up, proving his newfound agility.

"He's right where he needs to be," Tinsley concludes. "He's a high-level athlete, and with some guidance, he's mastering the art of base-stealing and agility."

So, what do you think? Is Henderson's journey inspiring? Do you think his hard work will pay off on the field? We'd love to hear your thoughts in the comments!
