The Progression System

Simple Progression That Actually Works.

Most workout apps increase weight on a schedule. Add 5 pounds every week. Increase after every session. Hope your body keeps up.

MoveIron takes a different approach.

The system watches your performance and adjusts based on evidence — not assumptions.

The Philosophy

Two principles behind the system.

Increases are based on performance.
Most training apps assume progress. MoveIron requires proof. You only increase weight when you've demonstrated you can handle the current load — every rep, every set. No guessing. No arbitrary jumps.
Different lifts follow different rules.
A heavy barbell squat should not progress the same way as a cable face pull. Compound lifts can grow faster. Accessory work needs more evidence. Isolation movements require two consecutive top-range sessions before increasing. The system encodes rules appropriate to each type of lift.
Strength compounds when progression is consistent — not forced.
Structure

The session cycle.

Every movement runs on a rolling session cycle. Each phase has a different rep target — and only one phase is where weight can actually change.

Phase 1
Low reps
Bottom of the rep range. Focus on form and familiarity at the current weight.
Phase 2
Mid reps
Middle of the range. Volume builds. Confidence in the weight grows.
Phase 3
Top reps
The only week where weight changes can occur. Ready to increase here.

Phases 1 and 2 are intentionally hold phases. Weight stays constant as long as you're hitting reps — with one exception: if any set falls below the minimum, weight still drops. Outside of that, these phases are lighter by design, giving joints, connective tissue, and the nervous system time to recover.

The cycle acts like a built-in autoregulation system. You never have to decide when to back off. It happens automatically.

The Increase Rule

Double progression.

Weight increases happen through double progression. You must hit every prescribed rep in every set before weight goes up.

Miss even one rep? The weight stays.
Hit them all? The weight goes up.

The threshold differs by lift type:

Compound lifts (squat, bench, row)
One clean Phase 3 session at the top of the rep range is enough. Weight increases next session.
Accessory and isolation lifts
Two consecutive Phase 3 sessions at the top of the range before weight moves. Smaller muscles benefit from more accumulated evidence before adding load.
Guardrails

Even when you're ready, a few rules apply.

These guardrails exist to keep progression sustainable over months, not just weeks.

Minimum spacing between increases
Secondary and accessory lifts must have a minimum number of Phase 3 sessions pass since the last increase before the next one is allowed. This prevents micro-jumps every cycle and ensures the lift has truly adapted.
Session increase cap
Only a limited number of exercises can increase in a single workout. If the cap is reached, remaining lifts hold until next time. Your body can only absorb so much new stress in one session.
Increments scaled by lift type
Bigger lifts take bigger jumps. Smaller lifts take smaller ones.
Lower body compounds
(squat, deadlift)
~5 kg / 10 lb
Upper body compounds
(bench, row, press)
~2.5 kg / 5 lb
Accessory lifts
(lunges, hip thrust)
~2.5 kg / 5 lb
Isolation work
(curls, face pulls)
~2 kg / 5 lb
Weight Reductions

Sometimes the right move is to reduce.

If any set falls below the minimum rep target, the system automatically reduces the load by 5%.

If you couldn't hit the minimum, the weight was too heavy.

Lower slightly, rebuild clean reps, and progress again. There's no debate, no override. The data decides.

This prevents the common mistake of staying at a weight you can't actually handle — accumulating poor reps, grinding form into the ground, and eventually stalling anyway.

Recovery

Stalls and deload weeks.

Compound and secondary lifts accumulate fatigue over time. Progress doesn't always look like improvement — sometimes it looks like staying the same for too long.

MoveIron tracks stalls automatically. A stall is when your Phase 3 performance fails to improve compared to the previous Phase 3 — total reps didn't increase, and no additional sets reached the top of the range. If the weight changed between sessions, the comparison resets automatically.

Plateau recovery — three stalls in a row
After three consecutive stalls, a recovery week triggers automatically. Weight decreases, volume may reduce, and accumulated fatigue clears.
Scheduled active recovery — every 12 Phase 3 sessions
Even without stalling, the system prescribes a lighter session after every 12 Phase 3 sessions. Fatigue accumulates before performance visibly drops — this prompts a recovery before you need one.

After any recovery week expires, the lift returns to the previous working weight — not the reduced weight. The deload is about shedding fatigue, not setting you back.

If deloads keep repeating on the same lift, the system automatically reduces the increment — halving it after every two consecutive recoveries, down to a minimum of 1.25 kg. Progress continues, just at a pace the body can actually absorb.

Accessory and isolation lifts do not trigger deloads. They don't accumulate the same kind of systemic fatigue. If they stall, they simply hold until the next session.

Under the Hood

What the app tracks for every lift.

Behind every exercise, the system maintains a full picture of your history and state — none of which you ever need to think about.

Users never see these numbers. They simply see the prescribed weight and whether the lift is ready to progress — along with a badge explaining the current status.
