About Global Training Report 

Est. 2000



Global Training Report (GTR) began publication in 2000 as a 100%  no-agenda, no-spin, no-politics, free service to practitioners and fans of Brazilian jiu-jitsu, boxing, judo, wrestling, Muay Thai, and other reality-oriented martial arts and combat sports. 

Reports, interviews, and articles cover the period 2000 to 2021 (a few were written as early as 1993).

From January 10, 2013, GTR introduced the GTR series of books specializing in jiu-jitsu history, published exclusively by GTR Publications. So far there are seven books in the series, with two more coming approximately winter/spring of 2022 and one more in 2023. Click for catalog.

About Roberto Pedreira: Roberto Pedreira is the author of Jiu-Jitsu in the South Zone, 1997-2008, Choque 1, 1856-1949, Choque 2, 1950-1960, Choque 3, 1961-1999, Craze 1, 1854-1904. Craze 2, 1905-1914;  Craze 3, 1915-1934; Craze 4: 1934-1964 (forthcoming early 2022) and The Origins and Evolution of Modern Jiu-Jitsu (forthcoming 2023). He has published the Global Training Report since 2000 and has been training Brazilian Jiu-Jitsu since 1994, in addition to other arts including English boxing, Japanese Jūdō, and Muay Thai (มวยไทย) among various others. Previously he trained Gōjū-ryū karate (剛柔流唐手), Jeet Kune Do, Korean Hapkido  (합기도, 合気道, aka 국술원) and a few other styles. He has no prejudice against any style but likes meaningful contact.

Roberto has also written several works of fiction which will (si Deus quiser) in the near future become highly profitable long-running HBO series or movie franchises. They are reality-based and involve strippers, MMA and jiu-jitsu fighters, forbidden islands, and arrogant professors, among other things. They include The Case of the Curious Cam-Girl, and The Forbidden Fortress of Professor Pakchang Tong.
