Weekly slots
Tuesday quality session · Friday easy Lone Soldier option
Equipment
Suitable running surface, trainers and a watch
Starting point
Use walk–jog intervals for the easy session if you cannot yet run comfortably for 20 minutes. If the quality session cannot be controlled at the prescribed effort, repeat week 1 or ask your PTI for a lower starting dose.
Rest
Use the recovery stated for each interval. Easy sessions should allow conversation.

Increase duration only when the previous week was comfortable and recovery is normal. Repeat a week rather than force the next progression.

If you use MSFT or A3, ask your PTI to adapt the aerobic work to that assessment and any medical restrictions. This running plan does not prescribe A3 testing or replace medical advice.

Programme guidance and preparation

Fit the programme to your training

Six-week plans for aerobic fitness, hex-bar deadlift, press-ups and pull-ups. Agree your starting point with your PTI; follow medical restrictions.

Agree the starting point and weekly workload with your PTI. Use one aerobic focus and/or selected strength work within existing sessions. If combining deadlift, press-up and pull-up work, build them into the same two strength sessions and reduce accessories; do not add six extra sessions to unit PT.

Warm up for 8–10 minutes, including easy movement and progressively lighter-to-working practice sets for lifting. Finish with about 5 minutes of easy movement. Allow at least 48 hours between hard sessions for the same muscle groups and adjust around Wednesday sport, loaded marching and duty demands.

Understand effort and progression

RPE means perceived effort on a 0–10 scale. Easy aerobic work is about 3–4, controlled intervals about 6–7. For lifting, RPE 6 is approximately 4 good repetitions in reserve, RPE 7 about 3 and RPE 8 about 2. These estimates guide load selection; technique takes priority.

Week 4 reduces volume; week 6 reduces fatigue before a PTI-led review. Repeat or reduce a week if recovery is poor. Follow medical restrictions; ask your PTI or clinician before using a plan if you are injured, returning from illness or not accustomed to this activity.

Review your development

Use your fitness card to record each SCA element separately against the v4.0 levels. Improvement in one element does not create an overall SCA grade. Your PTI decides when and how a formal assessment is delivered.
