For runners
Runners come to me after the third calf strain, or the second season of shin pain, having been told to strengthen without being told what that means.
The block runs two sessions a week, both short, both built around one-leg work and one heavy lift. It is written to sit inside your running week rather than fight it, so the hard days move when your long run moves and I ask you to send me your week before each block of three.
The first eight weeks feel too easy to most people. That is the intended feeling and it is why the tenth week goes as well as it does.
