The stacked Yokkao Extreme card goes gown on January 21, and among the great lineup of fighters on the card are the Petrosyan brothers. Giorgio is fighting Abraham Roqueni and Armen is fighting Djime Coulibaly. Italian site muaythaicombat.it today released a video that gives a look into the Petrosyan brothers' training, something we don't get to see too often. Strength and conditioning training is mostly shown but the actual kickboxing training is towards the end. Check out the video and besides watching Giorgio and Armen train, see if you can critique their form on the leg press.
