Your Real Energy Budget
A simple calculator to plan your training based on the life you’re actually living
Most people in their late 30s, 40s, and 50s don’t quit training because they’re weak. They fall off because they’re training on an energy budget they’ve never been taught to read.
They expect their body to perform the same regardless of stress, sleep, or life-load. They assume fatigue is a motivation problem instead of an allocation problem.
It’s not.
In midlife, your energy isn’t replenished overnight — it’s allocated, borrowed, taxed, pulled from multiple directions, and often already spoken for before you ever step into a gym or lace up your Hokas.
And if you don’t know where your energy is actually going, you’ll keep blaming your discipline for something that’s really an accounting issue.
On Tuesday, I shared the truth behind midlife fatigue — that it isn’t decline, it’s accumulated life, and that your body is no longer responding to the same conditions you had at 25.
For me, the shift wasn’t just accepting that truth.
It was learning how to budget my energy the same way I budget time or money — consciously, honestly, and with respect for the terrain I’m navigating now.
Today, I want to give you a system you can use every Sunday or Monday in under five minutes.
It tells you exactly:
What you have
What you’re spending
What kind of training your week can actually support
This is the Midlife Energy Budget.
The Midlife Energy Budget
Grab a notepad or open your Notes app.
The rules are simple:
Only count what is scheduled or guaranteed
No predictions
No wishful thinking
Just reality
🚩 NOTE: Recurring habits count as ONE deposit — not one per day.
Your nervous system adapts to routines. 5 consistent lunchtime walks is a great routine, but it’s not considered 5 separate boosts. Your lunchtime walks count as one stabilizing force in your week. Same with a nightly wind-down routine, morning wake-up stretch, daily journaling, etc. One weekly deposit for each recurring habit.
Meanwhile, if it’s special, unusual, or deliberately added for recovery that week, count it separately (e.g. a massage you booked, deliberate rest day, planned solo hike, therapy session, a committed date night with your partner, weekend leisure trip, etc.). They each count as +1.
1) List your drains for the week
Each drain = –1 point.
These must be scheduled on the calendar or inevitable:
work deadlines
early mornings
kid scheduling / events out of the norm
tough conversations you’re anticipating
work travel
medical appointments
veterinary appointment
social obligations
a recurring emotional load day you already expect (e.g., custody exchange)
anything stressful that can’t be avoided
Add up your drains. It should be a negative number (e.g. -3 if you have 3 drains).
If a new drain pops up during the week, don’t redo the math — just lower your Energy Budget by one level for the next day.
2) List your deposits for the week
Each deposit = +1 point.
Remember, recurring habits count as 1 deposit.
These must be scheduled or guaranteed:
a planned rest day
a morning walk you always take
therapy
cleaning service scheduled
free evening blocked out
massage or spa appointment
date night
time outside
time alone
dinner with an old friend
a hobby session you’ve committed to
Add up your deposits. This will usually be a positive number (e.g., +6 if you have 6 deposits).
If you have zero, don’t beat yourself up — just add one scheduled deposit to your week. One planned supportive moment is enough to change your Energy Budget.
3) Calculate and evaluate your Energy Budget score
Use the formula:
⭐ Energy Budget = Drains + Deposits
(for example: -3 drains + 6 deposits = +3 total score)
Now evaluate your score:
High budget (≥ +3)
You have room to build during your training. Push intensity if you want to.
This can include:
Heavier strength (this is a good week to increase weight or reps slightly)
Higher volume
AMRAP (as many reps as possible)
Challenging hikes or rucks
Intense cycling, rowing, or swim sessions
Interval training
Training skill development (learning a new routine, new machines, etc.)
Hot yoga
Medium budget (–2 to +2)
Train consistently. Avoid unnecessary intensity.
This is where most midlife weeks land — steady, workable, and perfect for building consistency.
Moderate strength (stick with current resistance load)
Zone 2 cardio
Simple conditioning
Shorter sessions
Technique work
Non-heated moderate yoga or pilates
Low budget (≤ –3)
Restore. Keep training supportive, not taxing.
Conversational walking or hiking
Light rucking
Stretching
Mobility work
Restorative yoga
This is how to stay consistent — not by pushing through everything, but by budgeting your energy realistically and training inside those limits.
Your week stops fighting you. Your workouts become sustainable. Your progress becomes repeatable.
Remember, movement is freedom.

P.S. Tuesday I’m opening a Black Friday offer for a short December reset — simple, realistic, and built around the Energy Budget system. If you want to feel more grounded heading into the holidays, keep an eye out.
P.P.S. Black Friday through Cyber Monday I’m also offering a discount on the paid Substack upgrade. If you’ve been thinking about joining, this will be the best time to do it.
