Strength Progression Planner

Introduction:

Strength progression is the planned change in training stress over a block. The stress can rise through heavier loads, more reps, more sets, more weekly exposures, shorter rest, or harder exercise variations. For barbell planning, load and volume are the simplest levers to audit because they can be written week by week.

A good progression is earned by repeatable work, not by a calendar alone. Adding 2.5 kg every week can be reasonable for a newer squat block and too aggressive for an advanced overhead press. Smaller jumps, rep-first progress, and planned deloads help keep the block productive when strength gains slow or recovery becomes the limiting factor.

Linear progression adds load on loading weeks. Double progression holds the same load while reps climb, then adds load after the top of the rep range is reached. Wave progression cycles lighter, medium, and heavier weeks so the block has variation without abandoning a clear anchor.

Deloads reduce load, set volume, or both. They do not make a program weak; they protect the next loading phase. The need for a deload depends on training age, lift choice, proximity to failure, sleep, pain, and how often the lift appears each week.

Any projected block should be checked against bar speed, technique, missed reps, soreness, and life stress. A table can show a sensible next load, but the lifter still has to earn that load with clean reps and a recoverable amount of work.

How to Use This Tool:

Plan one main lift at a time. Upper-body lifts often need smaller jumps than lower-body lifts, so the lift choice affects default increases and review thresholds.

1. Choose a Progression model: linear weekly load, double progression, or three-week wave.
2. Select the Lift, enter the Current working load, and choose kg or lb. Use a repeatable work-set load, not an all-time max single.
3. Set Work sets per session, Starting reps per set, and, for double progression, Rep cap before adding load.
4. Choose the block length, weekly exposures, load jump, and planned deload cadence. The table uses exposures per week to estimate weekly volume.
5. Open Advanced to set training level, load rounding, deload load target, deload set volume, and target reps in reserve.
6. Read Rule Checks before trusting the peak. Warnings often come from jumps that are too large, no deload in a longer block, repeated rounded loads, large peak change, or too many weekly hard sets for the selected level.
7. Use Week Loads for the prescription, Load Curve for the trend, Progress Brief for a text summary, and JSON for a structured copy of the draft.

Interpreting Results:

Projected block reports the peak loading target, change from week 1, block duration, progression model, deload count, and any review flags. Treat the peak as the highest planned loading target, not a promise that every week will be completed.

The Week Loads table combines target load, set-and-rep prescription, weekly volume, and the progression rule for each week. A deload row uses reduced load and fewer sets; a repeated rounded load means the selected rounding increment hides a small raw increase.

A clear table can still be too aggressive. If bar speed slows sharply, reps miss, pain appears, or sleep and appetite worsen, hold load, reduce volume, switch to rep-first progress, or end the block early.

Technical Details:

The block is calculated from a normalized current load, progression model, weekly increase, rep target, deload rule, and rounding choice. Linear progression increments the load each loading week. Double progression increments reps within a range, then raises load and resets reps. The wave model applies a repeating light, medium, and heavy multiplier to a rising anchor.

Deload weeks are inserted by cadence. A deload row uses the previous loading target multiplied by the selected deload load percentage and trims work sets by the selected deload volume percentage. Weekly volume is then calculated from the row's displayed load, sets, reps, and weekly exposures.

Formula Core:

In a linear 8-week squat block starting at 100 kg with 2.5 kg jumps and a week-4 deload, loading week 3 targets 105 kg before rounding. Week 4 deloads from the previous loading target, then the next loading week resumes progression rather than treating the deload as a new max.

Rule Core:

Load rounding is applied after the model calculates the raw target. Exact output keeps decimal values, while auto rounding uses common lift-specific increments. Rounding can make two raw increases display as the same target, which is why the rule checks count repeated loading rows.

Safety Notes:

Strength plans should not be used to train through pain, numbness, sharp joint symptoms, dizziness, or medical restrictions. Use safeties, spotters, sound technique, and conservative jumps when loads approach personal limits.

The planner does not measure readiness, bar speed, or recovery. A low-friction week on paper can still be too much when accessory work, sport practice, job demands, or missed sleep are added.

Worked Examples:

Intermediate squat block. Start with 100 kg, 4 sets of 5, two exposures per week, 2.5 kg jumps, and a deload every fourth week. The block reaches a modest peak while trimming week 4 and week 8 if the deload cadence lands there.

Upper-body lift with rounding stalls. A 42.5 kg overhead press using 2.5 kg jumps may repeat loads after rounding. Switching auto rounding to 1.25 kg or using double progression gives the lifter a clearer next target.

Troubleshooting a review flag. If Load jump size says a jump is above the level threshold, lower the jump before changing the training level. Changing level only changes the audit threshold; it does not make the body recover faster.

High weekly exposure. Six sets per session across three exposures produces 18 hard sets for one lift before accessories. That can fit an intermediate threshold but may still be too much if the same muscle groups are trained hard elsewhere.
