Ruben Tabares has trained boxers including now retired heavyweight David Haye and British super middleweight champion George Groves.
While David Haye didn’t exactly cover himself in glory in his final outing against Wladimir Klitschko, it certainly wasn’t his fearsome conditioning that let him down. Groves, on the other hand, used his awesome cardio and strength to outbox the much heralded James DeGale over 12 rounds, earning himself the middleweight title in the process.
Tabares’s innovative workouts played a big role in getting both boxers into shape so you can imagine they’re no walk in the park. Want proof? Watch the MF boys struggle through one geared towards power endurance and upper-body strength.
