A Puerto Rican professional dunker, born 26 September 1997 in Mayagüez and now based in Davenport, Florida. He is known as The Puerto Rican Airbender, and he co-founded the jump-training company THP Strength with his coach John Evans.
His Instagram bio and his YouTube channel both state a 50.5-inch max vertical; the channel calls it “the highest officially tested vertical on the planet” and Wikipedia records it as a former world record, tested at The Dunk Camp. His DUNKMAN athlete page adds a 40-inch standing vertical, described there as reported. Earlier figures on the record are a 46-inch vertical around 2019 and a 48-inch test at 22.
Quai 54 in Paris (2019), where he dunked over Blake Griffin; gold on the FIBA 3x3 World Tour at Montreal and the Utsunomiya Final, plus silver at Mexico City (all 2019); Dunk Battle 2022; and the 2022 Venice Beach Dunk Contest. In 2026 he won his DUNKMAN Group C qualifier pool with a 9.35 and qualified for the league's first World Championship.
His coaching company, co-founded with his own coach John Evans. It sells a subscription jump-training membership — custom weekly programming, daily coach access through a group chat, injury-specific pain tracks and a private community — plus a six-week vertical jump challenge run through the TeamBuildr app. The trading entities named in the site's own policies are THPstrength LLC and Exceptional Strength LLC.
No price is published. thpstrength.com routes every visitor through an application form and a 20-minute qualification call, and the terms say the challenge deposit amount is “clearly displayed during checkout”. Third-party review sites quote monthly figures, but those are not his own published prices, so no number is stated here.
That specific figure could not be sourced. What his own site says is that its system is “the system we use with thousands of jump athletes”, built from “280+ training cycles tested on thousands of athletes”. Wikipedia says he and Evans have coached four of the highest jumpers in the world; his YouTube channel says he has helped three athletes record a 50-inch vertical, including world record holder Dillan McCarthy. A post of his on X from November 2023 says “the average athlete I train gains 4-7 inches of vertical in 6 months”.

No — that appears to be a mix-up. Isaiah Rivera the dunker was born in Mayagüez, Puerto Rico and lives in Davenport, Florida. There is a separate Illinois basketball player of the same name from Geneseo, near the Quad Cities, who played at Colorado State and UIC. They are different people.
