Second session with Musashi:

• My cross is weak cos I bend my elbow outwards as I throw it  – ‘keep the elbow tucked in!’
• My duck is weak (and dangerous) cos I bend from the waist – ‘be like a pencil’ he keeps telling me – that is, keep my torso straight and bend from the knees.
• I move too much – waste energy.
• And my back is really sore.

But I loved it. Think I’ve found a new religion.
