The personal operating system of
Sam Morrison
“Living well for decades,
not merely performing well today.”
Build an aerobic base.
Keep some intensity.
Do not make every session intense.
Life OS is a personal handbook for maintaining strength, energy, health, independence, and enjoyment over the long term.
The aim is not to become the fittest person in the room. It is to remain capable, mentally sharp, physically resilient, and able to enjoy sport, travel, work, relationships, and everyday life for as many years as possible.
The guiding question is simple:
Will 70-year-old Sam thank me for this?
This question is not designed to remove fun or spontaneity. It is a reminder to favour habits that compound: enough sleep, regular movement, meaningful training, sensible nutrition, strong relationships, proper recovery, and preventive care.
FOUNDATION
Health span matters more than optimisation theatre.
A missed workout is a small event. Regularly losing sleep is a system problem.
Training should fit around recovery rather than repeatedly borrowing from it.
A good plan followed for years is more valuable than a perfect plan followed for three weeks.
The goal is to build a week that still works during busy periods, lower motivation, travel, illness, and ordinary life.
Muscle supports strength, balance, insulin sensitivity, bone loading, physical confidence, and independence.
Strength training is not only about appearance or performance. It is a long-term reserve of capacity.
Swimming, tennis, conditioning, walking, and appropriately scaled high-intensity work all contribute to cardiovascular fitness.
The aim is to preserve both an aerobic base and the ability to work hard when needed.
A training session does not cancel out an otherwise sedentary day.
Walking, changing position, using stairs, and breaking up long periods of sitting all matter.
Rest days, easier weeks, good food, sufficient sleep, and time away from work are not signs of lost momentum.
They are part of the programme.
Tennis, swimming, CrossFit, and team training are valuable partly because they are engaging.
The best long-term plan includes activities Sam genuinely wants to continue.
A supplement should have a clear purpose, a plausible benefit, an acceptable safety profile, and a reason to remain in the routine.
More is not automatically better.
Target: approximately three meaningful strength exposures each week.
Purpose:
CrossFit, Team Training, and occasional focused strength work can all contribute.
The priority is not maximum weekly volume. It is sustained progress without repeatedly training through poor recovery or preventable injury.
FOUNDATION
Strength is a long-term health investment.
Target: a mixture of easier aerobic work, sport, and some higher-intensity training.
Swimming is particularly useful because it provides cardiovascular work with relatively low impact.
Tennis adds agility, coordination, speed, decision-making, and social enjoyment.
CrossFit and Conditioning contribute higher-intensity work, but not every session needs to become a test.
FOUNDATION
Build an aerobic base. Keep some intensity. Do not make every session intense.
Target: 10 to 15 minutes on most days.
Priority areas:
Mobility should be practical. The aim is to move well enough to train, play tennis, swim, reach, rotate, squat, and walk comfortably.
Stretching is useful where it solves a real restriction or helps relaxation. It does not need to become a separate sport.
PERSONAL
Calf, ankle, and foot work remain part of ongoing maintenance even after the current injury has resolved.
Recovery includes:
The plan should create energy for life rather than consume all available energy.
FOUNDATION
A healthy routine should make ordinary life feel better.

Then reset the week
Core rhythm Optional when recovery and work allow
This is the default week once fully fit enough to train normally.
It is a framework, not a contract.
Evening: CrossFit, 6:00–7:00 pm
Purpose:
Also:
Morning: additional swim session
Preferred focus:
This is a better complement to the week than adding another hard conditioning session.
It also creates two swims each week without automatically removing a CrossFit class.
Tuesday evening is deliberately lighter:
EVOLVING
If strength becomes a clear weakness, Tuesday can occasionally become a focused gym strength session instead.
Evening: Tennis, 7:00–8:00 pm
Purpose:
Avoid adding another demanding session unless energy and recovery are clearly good.
Morning: Swim, 7:15–8:15 am
Evening: Tennis, 8:00–9:00 pm
This is the highest-load day of the week.
Priorities:
Optional: CrossFit, 12:00–1:00 pm
This depends on work, sleep, energy, and the accumulated load from Thursday.
Friday is optional by design.
If the class does not happen, the day still succeeds with:
OPTIONAL
Never turn a missed optional session into guilt.
Alternate between:
Team Training is longer and may create more fatigue, so the following Sunday should be adjusted when needed.
Conditioning, 10:00–11:00 am
Then:
Sunday should prepare the next week without becoming an exhausting list of chores.

A successful week does not require attending every possible class.
This is already a substantial week.
A 13-class monthly allowance is likely to fit the realistic plan better than a 22-class allowance.
Three classes per week is approximately 13 sessions per month.
The lower allowance may reduce the psychological pressure to “use up” classes while still supporting consistent training.
Review after three months based on actual attendance rather than aspiration.
REVIEW QUARTERLY
The Hyrox class felt good, but the early start created friction and the wider membership was not being used consistently.
Do not restart simply because it is inexpensive.
Restart only when there is a realistic and specific use case, such as:
When work, motivation, illness, or life disrupts the plan, use the minimum viable day.
A minimum viable day includes:
This prevents all-or-nothing thinking.
A reduced day still counts.
CrossFit is useful for:
Use it as a broad training tool rather than a weekly test of character.
Good scaling is a sign of intelligent training.
Do not chase intensity when:
Two swims each week provide a strong low-impact aerobic foundation.
Thursday coached or structured swim.
Tuesday technique and aerobic swim.
Suggested balance:
The second swim should usually leave Sam feeling better rather than depleted.
Tennis is both physical training and a skill practice.
Keep both weekly sessions while they remain enjoyable and compatible with recovery.
Tennis contributes:
It is not necessary to add running solely because running is often associated with fitness.
Running may be added once fully fit and robust, but it is not mandatory.
Swimming, tennis, conditioning, walking, and CrossFit already provide substantial cardiovascular work.
If introduced:
Use short, repeatable routines.
Suggested daily categories:
Static stretching is most useful after training, in the evening, or where a specific restriction exists.
The aim is not dietary perfection.
The aim is reliable, enjoyable nutrition that supports training, health, and recovery.
At approximately 78 kg body weight, a practical daily target is around:
110 to 130 g protein per day
This does not need to be exact every day.
Spread protein across meals where possible.
Useful sources include:
Six Simmer meals each week reduce decision fatigue and make consistent eating easier.
Use them strategically for the busiest lunches and evenings.
Add vegetables, fruit, yoghurt, or another simple side where the meal is light on fibre or total volume.
Plan at least three additional lunches or dinners each week.
Good default choices:
Smoothies are useful when they contain enough substance to count as a meal or substantial snack.
A balanced smoothie may include:
Creatine should not depend on whether a smoothie happens that day.
Aim for variety rather than chasing a perfect number.
Regularly include:
A reasonable baseline is approximately 2 to 3 litres of fluid per day, adjusted for body size, weather, sweat, and training.
More may be needed on Thursday and during longer or hotter sessions.
Electrolytes are most useful during prolonged, hot, or unusually sweaty exercise. They are not automatically required every day.
Treat alcohol as an intentional choice rather than a nightly default.
No need for moral language.
Simply recognise that alcohol can affect sleep, recovery, appetite, and training quality.
Supplements support the plan. They do not create the plan.
Status: Keep
Tier: Foundation
Dose: 5 g daily
Purpose:
Take daily rather than only on smoothie days.
Mixing it into morning coffee with oat milk and collagen is a practical option if the taste and texture are acceptable.
Timing is less important than consistency.
Status: Keep as needed
Tier: Foundation food tool
Protein powder is a convenient food rather than a requirement.
Use beef or pea protein isolate according to preference, digestion, and taste.
Its role is to help reach the daily protein target when food alone would be inconvenient.
Status: Keep
Tier: Targeted support
Potential role:
The evidence is not as strong as it is for creatine or adequate total protein.
Consistency is likely more important than perfect timing.
Taking collagen near training with a source of vitamin C is a reasonable optional refinement, but it should not complicate the routine.
Status: Keep for now
Tier: Nutritional insurance
Review: Annually
The current product includes:
The pack provides a total of 25 micrograms, or 1,000 IU, of vitamin D per daily serving.
The omega-3 component provides a relatively modest amount of marine omega-3.
The product is reasonable as a convenient all-in-one, but it should not be assumed to replace a varied diet.
Take it with the main meal as directed.
Status: Review
Tier: Blood-test guided
The separate Vitabiotics vitamin D product provides 3,000 IU.
Together with Wellman Max, the total is approximately 4,000 IU per day.
That is around the commonly cited adult upper daily intake, so it is not an ideal long-term default without a reason.
A vitamin D blood test can help determine whether the additional tablet remains appropriate.
Discuss sustained higher-dose supplementation with a GP, pharmacist, or other qualified clinician.
Status: Food first
Tier: Targeted support
Wellman Max provides only a modest amount of marine omega-3.
Prioritise oily fish approximately once or twice per week where practical.
A dedicated omega-3 supplement may be considered if oily fish intake is consistently low, but it should be selected based on actual EPA and DHA content rather than the headline amount of fish oil.
Status: Optional
Tier: Experimental / enjoyment
The ritual, caffeine, taste, and enjoyment may be the main benefits.
Some included ingredients may be interesting, but they should not be treated as essential longevity interventions.
Keep them if they improve the morning and are affordable.
Status: Optional
Tier: Experimental
Priority: First to remove when simplifying
AgeMate is not currently a foundation item.
The likely incremental benefit is uncertain, particularly alongside Wellman Max and separate vitamin D.
It may remain as an optional experiment, but it should not displace spending on good food, sleep, training, preventive care, or useful equipment.
The more uncertain the evidence, the less complicated and expensive the experiment should be.
Aim for approximately 7.5 to 8 hours in bed, allowing enough opportunity to sleep.
Current goal:
Early swim days require an earlier bedtime rather than simply removing sleep.
Morning coffee is compatible with the plan.
Avoid allowing caffeine to drift later into the day if it begins to affect sleep onset or sleep quality.
Include at least one lower-demand evening each week.
This means:
Recovery can include:
Every 8 to 12 weeks, or sooner when needed, reduce training volume or intensity.
Signs that an easier week may help:
Preventive care should be proportionate and clinically guided.
More testing is not always better.
Check periodically with a validated upper-arm monitor.
Take several seated readings rather than relying on one isolated number.
Discuss persistent high readings with a clinician.
Track trends rather than daily fluctuations.
The aim is a stable, healthy body composition that supports strength and energy.
Useful as a trend marker rather than a score.
A sudden sustained change may reflect illness, poor recovery, stress, or reduced fitness.
Once a year, review:
Blood tests should be guided by symptoms, family history, risk factors, previous results, and clinician advice.
Potential tests may include:
Avoid treating a broad private panel as a substitute for clinical interpretation.
Attend routine eye examinations at the advised interval.
Seek earlier review for:
Pay attention to new or changing lesions.
Seek clinical review for concerning changes rather than relying on self-diagnosis.
Review age, occupation, travel, and risk-based vaccination eligibility annually.
Follow NHS invitations and discuss personal or family risk factors with a GP.
The annual manual review should be updated as age-based eligibility changes.
The dashboard is a prompt for judgement, not an automated medical diagnosis.

Response:
Seek appropriate professional or emergency help.
Do not use the training plan to explain away serious symptoms.
Spend five to ten minutes on Sunday asking:

Review:
Use actual behaviour to change memberships and commitments.
Do not pay for the person Sam imagines becoming. Pay for the routine Sam is realistically using.
Each year:

Life OS is not a demand for perfect behaviour.
It is a way to make good decisions easier.
The healthiest version of Sam is not the one who never misses a session, never eats dessert, or owns the largest supplement stack.
It is the one who keeps returning to the basics:
Build a life that health makes possible.
