The Franks brothers, famously, are allowed to follow their own training programmes so if All Blacks coach Steve Hansen wanted to get an idea of what they were up to he could do worse than read their new book.
Training Tough is a collaboration not surprisingly dominated by what Ben and Owen, All Blacks props and former teammates at the Crusaders - elder brother Ben is now at the Hurricanes - get up to in the gym.
It is designed for young athletes who already know their dumbbells from their barbells and want specific exercises to build strength and power.
An in-depth look at the Franks brothers and their relationship, this is not. But there is an introduction by Phil Gifford titled "To be Franks" in which their dad, Ken, tells an interesting story about his stint in the Australian Navy and almost coming to grief in a submarine.
It's made clear how hard the brothers have had to work to get where they are. Photos taken when they were children or teenagers give no clue as to how they will end up after years of toil in the gym or training field.
