Brendan Donovan has been using TheStack for over a year to build real, measurable bat speed gains.
No shortcuts. No guessing.
After his first program last year, he saw a +4 mph increase in bat speed on his way to his first All-Star Game.
Good things happen when you trust the science & dedicate yourself to the craft.
Donnie works hard, stays consistent, and we couldn’t be more proud to have him on board as an official Stack Athlete!
