A record holder with eight IBJJF world championship titles in five different weight classes,[a] as well as multiple wins at every major international tournament, Lo is considered one of the most accomplished jiu-jitsu competitors of all time.

[1] That same year Lo defeated Lucas Lepri in Rio de Janeiro for the GP lightweight title, becoming Copa Podio champion for the fourth time.

[21] Going up a weight class again to medium heavyweight (under 88.3 kg (195 lb)), Lo won the 2015 World (his fourth title in a row[22]), the Pan Am and the Abu Dhabi Pro tournaments.

[10] In October 2016, Lo made history by becoming the first ever Copa Podio triple crown champion: winning three consecutive Grand Prix titles in three separate weight classes: Lightweight, Middleweight and Heavyweight, all in the same year; a performance never before accomplished in the sport of jiu-jitsu.

Lo then won double gold at Pan after defeating ultra heavyweight João Gabriel Rocha in the open weight final.

[26] During the ADCC North American West Coast Trials, held in Anaheim California on 15 April 2017, Lo defeated Gordon Ryan in a Superfight by 4×0 pts.

[27] Invited to the 2017 ADCC World Championships in Espoo, Finland, competing for the first time for the -88 kilograms (194 lb) title, Lo was eliminated in the first round by Asia and Oceania Trials winner Craig Jones.

[b][30] In May 2018 Lo entered the world championship as super-heavyweight (under 100.5 kg (222 lb)) but dislocated his shoulder twice during the super-heavyweight final and was unable to continue;[31] in a surprising move, his close friend Marcus Buchecha, who he was supposed to face in the Absolute final, forfeited his match to give Lo the 2018 open weight title, the only title missing in his career.

Competing for the open weight title, Lo defeated Keenan Cornelius in the semi-final but made the final a close out[c] when he gave Buchecha the victory, returning the previous year favour.

[41][23] That last title placed him at number 1 in the medium-heavy male gi division for the 2021–2022 season of the International Brazilian Jiu-Jitsu Federation Ranking.

Lo won his first two matches against Rafael Paganini and William Tackett but was submitted by Lucas 'Hulk' Barbosa by rear-naked choke in the final.

[47] The International Brazilian Jiu-Jitsu Federation called Lo "one of the greatest athletes our sport has ever produced" and "an example of a true black belt, martial artist and champion on and off the mats".

[60] Lo's fellow athletes, many wearing their Jiu-Jitsu Gi, lined the way from the chapel to the cemetery in a guard of honour, while his body was being carried in an open coffin.
