Dr. Pak's research says clients can get stronger doing less. Here's how to use that as a floor for your busiest clients - not an excuse to under-program.
The minimum effective dose is the least training that still drives progress. For an online coaching roster full of time-poor adults, that's not a fringe idea - it's the difference between a client who keeps going through a hard month and one who quietly disappears. This breakdown covers Dr. Pak's argument in our own words, adds our honest take on where MED fits in a coaching business, and shows how to template a minimum-dose plan once and deploy it the moment a client's life gets in the way.
By Markus Evers · September 2026 · a Coachway video breakdown
the short version
Dr. Pak's video makes the evidence-based case that a small amount of hard, high-effort training still produces meaningful strength and muscle gains - and he is careful to frame that as a floor for when time, recovery or motivation are short, not proof that less is always better. The one thing a coach should do about it: build a minimum-dose plan for every client in advance, and deploy it the week their life gets in the way, so progress and retention survive the hard stretches instead of collapsing into all-or-nothing.

Who is Dr. Pak, and why coaches watch
Dr. Pak is a sport scientist whose doctoral research centred on the minimum dose of training required to build one-rep-max strength in powerlifters - combining a review of the literature, training studies, and interviews with elite powerlifting coaches and athletes. He's become the go-to evidence-based voice on minimalist training, and he publishes structured minimum-dose templates for both strength and hypertrophy. For coaches he matters because his subject is not the genetically gifted athlete with unlimited gym time - it's the person who can only give training a small slice of their week, which describes most of the clients on an online roster. This page reads his work through that lens: not "how little can I get away with," but "what's the smallest plan I can hand a busy client that still moves the needle."
What Dr. Pak actually argues (our summary)
This is our summary of the ideas in the video and his published research, in our own words - not a transcript. Watch the original for his exact studies, templates and numbers.
- 1
A small dose still works. The core finding is that trained lifters can keep making meaningful strength and muscle gains on far less training than most programs prescribe - the least effective dose is lower than most people assume.
- 2
Effort is what makes the small dose pay off. When volume is low, the sets that remain have to be genuinely hard - taken close to failure. Intensity of effort is how a minimal plan compensates for the sets it isn't doing.
- 3
MED is a floor, not the optimum. He is explicit that this is a strategy for when time, recovery or motivation are limited - not a claim that less is always better. He notes that doing somewhat more can yield meaningfully more growth.
- 4
Prioritise the big lifts. With limited sets to spend, the compound movements that train the most muscle for the least time earn their place first. A minimal plan is a ruthless exercise-selection exercise.
- 5
The point is progress you can actually sustain. A small plan a person completes beats a big plan they abandon. MED is most valuable as the version of the program that survives a hard week, keeping momentum alive until there's room to do more.
Coachway's take
We think MED is one of the most underrated tools in a coach's kit, precisely because it solves a business problem, not just a training one. The client who ghosts you rarely does it because the program was wrong - they do it because life got loud and the plan didn't bend. A minimum effective dose is the bend. It lets a client stay in the game on a week they'd otherwise write off, and a client who stays in the game stays a client.
But we'd underline the honest framing hard, because it's easy to abuse. MED is a floor for constrained weeks, not the default you quietly hand everyone to save yourself programming time. Dr. Pak is clear that more can produce more, and a coach who parks a motivated client on a minimum dose is leaving results on the table. The skill is knowing which mode a client is in this week - full plan when life allows, minimum dose when it doesn't - and moving between them deliberately.
The coaching-specific point he doesn't have to worry about: he's writing for a reader who'll self-apply the research. You're managing twenty people who won't. So the value you add isn't knowing the minimum dose exists - it's building it in advance, spotting the week a client needs it, and switching them over before they miss enough sessions to spiral. That's a judgement call on live check-in data, and it's exactly the part a generic template can't do.
So our version of his advice is: set a weekly floor per lift and per muscle for every client, keep the remaining sets genuinely hard, and treat the minimum dose as a pre-built "bad week" mode you can deploy in seconds - then scale volume back up the moment their life opens up. Build it once as a template and it's ready before the client even tells you they're slammed.
One note on scope: this is general coaching and training education, not medical advice. A minimum-dose plan is still real training load - screen new and returning clients, work within your certification, and refer to a physician or physio when pain, injury or a medical condition is in play rather than coaching through it.
Build the "bad week" plan once, deploy it in seconds
MED only protects retention if you can deploy it faster than a client can lose momentum. That's what Coachway's workout builder is for: build a two-to-three-session minimum-dose plan as a reusable template - big lifts first, a small number of hard sets, rep ranges and effort targets set - then assign it to any client the week their schedule falls apart, instead of rebuilding a program under pressure. When life opens back up, you swap them back to the full plan just as fast, and client progress and check-ins let you actually see whether the small dose is holding strength and body composition before you decide to add volume again. That's the proof Dr. Pak's framing depends on - evidence the floor is still working, not a hope.

Minimum effective dose planner (the "bad week" template)
A fill-in planner you can copy for any client and deploy the week their life gets in the way. The default is a 2-3 session, big-lift-first minimum dose: keep the few sets genuinely hard, protect the floor, and scale back up when the client's schedule allows. The set ranges below are our coaching defaults for a floor, informed by the low-dose direction of Dr. Pak's research - not exact figures from the video. Set your own numbers per client.
Minimum-dose planner
The week (2-3 short sessions)
| Session | Priority lifts | Focus | Your notes |
|---|---|---|---|
| A | Squat + horizontal push | Legs, chest, shoulders | — |
| B | Hinge + vertical/row pull | Posterior chain, back | — |
| C (optional) | Press + weak-point work | Shoulders, arms, gaps | — |
Weekly floor per muscle (take sets close to failure)
| Muscle / lift | Hard sets / week (floor) | Effort | Scale-up trigger |
|---|---|---|---|
| Main lifts (squat/hinge/press) | 2-4 per lift | Close to failure | 2 consistent weeks |
| Legs (quads / hamstrings / glutes) | 3-6 | Close to failure | 2 consistent weeks |
| Back | 3-6 | Close to failure | 2 consistent weeks |
| Chest | 3-5 | Close to failure | 2 consistent weeks |
| Shoulders / arms (direct) | 2-4 | Close to failure | 2 consistent weeks |
How to use it: this is a floor to hold on hard weeks, not a permanent minimum. Keep the few sets genuinely hard, protect the numbers, and once the client hits the floor consistently for a couple of weeks, add sets back toward their full plan. Screen for pain or medical issues and refer out rather than coaching through them.

Minimum effective dose for clients - FAQ
What is the minimum effective dose for strength and muscle?
The minimum effective dose (MED) is the least training that still produces meaningful progress - the floor, not the ceiling. Dr. Pak's research on minimum-dose training in trained lifters points to two practical reads: a small number of hard, high-effort heavy sets per lift each week can still drive real strength gains over a training block, and a low number of hard sets per muscle each week can still add muscle. He is careful to frame this as a strategy for limited time, recovery or motivation - not a claim that less is always optimal. For a coach it is the program you reach for when a client's life is the constraint, so that progress continues instead of stopping.
How few sets per muscle can still build muscle?
In the evidence Dr. Pak reviews, a low number of hard sets per muscle group per week - in the rough neighbourhood of a handful of quality sets - can still produce meaningful hypertrophy in trained lifters, especially when those sets are taken close to failure. He is explicit that this is a floor for constrained situations, and that doing somewhat more can yield meaningfully more growth. So the coaching takeaway is not 'do the least forever' but 'know how low you can go without losing ground,' then add volume back as the client's schedule and recovery allow.
Is minimum effective dose training worse than higher-volume training?
Not worse - different job. Dr. Pak does not argue that less is better; he argues that a small dose still works, which is a different and more useful claim. Higher volume can produce more growth when a client has the time and recovery for it. MED is the tool for weeks when they do not: travel, deadlines, poor sleep, low motivation. Used honestly, it keeps results and adherence intact through the hard stretches instead of forcing an all-or-nothing choice, and it gives you a clean baseline to scale up from when life opens back up.
How should a coach program a minimum effective dose for busy clients?
Build two to three short sessions a week, prioritise the big compound lifts, and take the low number of sets close to failure so effort compensates for the missing volume. Set a weekly floor per lift and per muscle, and treat it as the line you protect on bad weeks rather than the plan for every week. Then use check-ins to confirm the small dose is still moving strength and body composition, and only add sets once consistency is proven. Framed to the client honestly, MED is a maintenance-to-progress floor for hard weeks - not a permanent minimum.
