Where to find him
Meet Isaiah

A 24-inch vertical,
then a 50.5-inch one

In his own words on his YouTube channel: he started working out to jump higher at 14, hit his first dunk at 16, entered his first professional dunk contest at 18, and at 19 nearly quit because of knee pain.

At 20 he met John Evans, the coach who got rid of that knee pain. At 21 he won his first international dunk contest. At 22 he tested a 48-inch vertical and started coaching full time. At 24 he tested the 50.5-inch vertical he is now known for.

He graduated from UCF with a degree in kinesiology and exercise science, moved in with Evans, and the two of them built THP Strength out of it.
