It's from his website. I think his younger bother translates it from Hebrew to English, so it's a bit embarrassing to read.
"Now I want to take a rest period for cleaning the head, some freedom to release the legs and muscles and rest. After that I started training in Las Vegas with the best trainer in the U.S. and come back with the group after the selected period."
Anyway, Omri will play for the national team, but he will also work in Vegas with Joe Abunassar. His name is not mentioned here, but I read that at an Israeli site.
I hope he'll follow a good and smart regimen, in which he'll improve his condition, but also finds enough rest for next season.
