    I`m a bit late to the party but he`s wearing nikes as a movement coach..? Cushion underneath your heals is the number 1 cause for lower back problems, chest spine weakness, overall bad posture, as well was neck issues….. Not trying to offend anyone! Kelly Starret is mentioning it several times. Just wear neutral shoes and many of your daily day by day problems will solve themselves!

    This guy is NOT from Hawai’i. He throws up shaka’s and says “Ohana” and “Mahalo” and everyone thinks he’s from Hawai’i. Just curious as to why someone would claim to be from Hawai’i when he’s not. He was born and raised in Southern California. Read this article from 2008 about his dad who was an LAPD Detective. Nowhere in the article does it say anything about Hawai’i. If you follow the timeline in the article there was no time that the Sakoda family lived in Hawai’i.

    It talks about how the dad learned “bushido values” character and integrity, respect for others, especially parents and older people. DO YOUR BEST, DON’T EVER GIVE UP”. Da Rulk learned it from his dad who learned it from his Japanese culture, not from an “old Hawai’i saying” like Da Rulk claims in this interview.

    But all that aside, his workouts are crazy. Old-school football drills, mma exercises renamed with multiple technical terms for each exercise.

    I think small simple steps are really the key of building a habit, building the momentum. Da Rulk's advice on don't overcomplicate things are very useful for anyone to be discipline, to stay committed. Thanks for the interview Tom.
