^aSessions will increase in intensity/load by 2.5–5% as tolerated between sessions during weeks 1–12 up to the max intensity/load for the fortnightly block, provided the duration (during weeks 1–6) remains the same for the sessions where intensity/load is changed
^bSessions will increase in duration by 5 min during weeks 1–6 up to the max time for that fortnightly block, provided the intensity/load remains the same for the session where duration is increased
