Progressive overload, without the add-weight-every-week myth
Volume, frequency, autoregulation, failure, deloads and rest: how the next session's load gets decided, topic by topic.
Short answer.
Progressive overload is not adding weight every week. It is raising demand steadily through any of its routes — load, reps, sets, density or range of motion — and doing it only when logged performance justifies it. In practice that means checking three things before increasing load: how many reps were left in reserve, how much weekly volume the client has been accumulating, and whether they are recovering between sessions. This guide walks through each of those decisions with the evidence behind it.

What this guide answers.
When to increase a client's load and when to hold it another week.
How much weekly volume each muscle needs, and the minimum that maintains.
How to read the RIR a client reports without overestimating their effort.
Whether to train to failure, on which lifts, and how often.
When to programme a deload, and how to tell one was needed.
The topics in this pillar.
What progressive overload is
The five routes to raising demand, and why load is only one of them.
RIR and autoregulation
Turning the reps-in-reserve a client reports into a load decision.
Weekly volume
Weekly sets per muscle group, and the minimum volume that holds what was gained.
Frequency
How often to train each muscle, and when more frequency stops adding.
Rep ranges
Why 8 to 12 is not magic, and what actually drives hypertrophy.
Failure, deloads and rest
When failure helps, when a deload is necessary, and how long to rest between sets.
Frequently asked questions
Steadily increasing training demand so the body keeps adapting. It has several routes: more load, more reps, more sets, shorter rest, or greater range of motion. Adding weight is the best known and is not always the right one.
When logged performance justifies it, not on a fixed schedule. If the client hit every target rep with reps to spare, there is room to increase. If they barely finished, holding the load another week usually produces more adaptation than forcing it.
After each session a client logs, Kaizer recalculates their estimated 1RM from the sets, reps and RIR recorded, and proposes the next session's load and reps. The coach approves every change and sets the minimum increments, so the final call stays theirs.
Yes. These are programming criteria, not product features, and they hold in a spreadsheet too. Software changes how long it takes to apply them to every client, not the criteria themselves.
