Whilst details of the spar are somewhat limited we were informed of several things from the sessions. Firstly the session has been recorded to help both men see what they can improve. The video, at least for now, has not been made public though it's great to hear that the footage does exist.
From the few other details we've discovered we've heard the men were sparring 4 minute rounds with 30 second intervals. This, done at altitude at Big Bear in California, is certainly done under with emphasis on improving a fighters stamina and although it was very difficult for Murata it does seem to have helped made Golovkin into the fighter he is.
We also aware that Murata stated Golovkin's fist is "hard as stone" something that former Golovkin opponents have all had to feel when sharing the ring with him. Murata did however have some success of his own and will have learned so much from sharing the ring with Golovkin, arguably the uncrowned Middleweight kingpin.
Golovkin, preparing for his July 26th bout with Daniel Geale (30-2, 16) will likely have enjoyed the sparring sessions which will have helped him sharpen his tools ahead of his 11th title defence. For Murata however it's been his first real chance to share the ring with a world class Middleweight and help get into shape ahead of a specialised camp for his next bout, which is widely expected to be in Singapore in October.
