Rankings — Coverage by Muscle and Equipment
Which muscle groups and equipment profiles have the most coverage in the PlainExercise database. Useful when deciding where to focus your programming.
Why rankings matter
The PlainExercise database has uneven coverage across muscle groups and equipment profiles. Large muscle groups (chest, back, legs) have many more exercises documented than smaller or more specialized ones (neck, forearms, Olympic lifting). Similarly, common equipment (bodyweight, dumbbells, barbell) has far deeper coverage than niche equipment.
This page makes the uneven coverage explicit. If you're programming training and want to emphasize a specific muscle, the ranking tells you how many options you have. If you're setting up a home gym and trying to decide on equipment, the ranking tells you which purchase opens up the most movements.

How to use this ranking
If you want to train your legs and have limited time, filter by the top leg muscle (quadriceps or hamstrings) and pick any exercise — with 100+ options you will never run out of variety. If you want to train a smaller muscle like forearms, expect fewer direct options; most forearm training comes as a side effect of grip-intensive compound lifts.
For equipment planning: buying the top-ranked equipment (bodyweight, dumbbells) gives you access to the most movements. Niche equipment that ranks low in this list unlocks few additional exercises, so its value depends on whether it enables a specific movement you can't get elsewhere.
Why coverage is uneven
The data sources that underpin PlainExercise — the open-licensed Free Exercise DB (CC0) and wger.de's exercise corpus (AGPL) — were assembled by community contributors over more than a decade. Contributors documented the movements they personally knew, used, and coached. That introduces three predictable forms of skew that are visible in the rankings on this page.
First, large compound movements get many entries. A squat, a deadlift, or a bench press each generate dozens of catalogued variations: high bar, low bar, paused, tempo, single-leg, deficit, banded, chain-loaded, against accommodating resistance, plus the half-dozen unilateral progressions and the regressions that physical therapists prescribe after injury. The taxonomy reflects how those movements are actually programmed in the field, which leads to muscles that anchor compounds (quadriceps, glutes, latissimus dorsi, pectoralis major) accumulating the largest counts.
Second, movements with multiple equipment options inflate counts. A row exists as a barbell row, a dumbbell row, a cable row, a T-bar row, a chest-supported row, a Pendlay row, an inverted-bodyweight row, and a banded row. Each of those is a distinct catalogue entry, so the underlying movement pattern (horizontal pull) is overrepresented relative to a movement pattern with few equipment substitutions (heavy farmer's carry, for instance, has fewer variations because the equipment is essentially fixed).
Third, niche muscles trail by an order of magnitude. Tibialis anterior, serratus anterior, neck flexors, deep abdominal stabilisers — these have small entry counts because they are typically trained as a side effect of compound movements, or with one or two dedicated exercises (calf raises, dead bug variations, neck harness). Their low ranking on this page is not a coverage gap to lament; it reflects how strength coaches and physiotherapists actually program these regions in practice.
Reading the equipment column
The equipment column lists the primary implement required by each exercise as classified by the upstream contributors. Substitutions are not collapsed: a "barbell" entry remains a barbell entry even if you could conceivably substitute a heavy dumbbell. This preserves the upstream catalogue intent and lets you filter realistically — if your gym does not have a barbell, you can scan past barbell entries rather than discover mid-warmup that the prescribed variation requires equipment you do not have.
For a home-gym audit, work the equipment ranking top-down. Bodyweight first (always free, always available); resistance bands second (a single set of progressively heavier bands unlocks dozens of pulldown, row, press, and pull-apart variations); adjustable dumbbells third (the highest count of variations per dollar spent); a single 45-pound plate fourth (loaded carries, halos, plate squats); a pull-up bar fifth. The remaining entries lower in the ranking each unlock specific movements that the cheaper equipment cannot fully replicate, but their incremental value drops sharply.
Limits of this ranking
Two limitations are worth flagging. First, the ranking counts catalogued variations, not training value. A muscle group with 200 catalogued exercises is not necessarily two-hundred times more trainable than one with two; you only need a small number of well-chosen movements to drive strength and hypertrophy. The ranking tells you about option breadth, not required volume.
Second, the ranking is computed at build time from the live PlainExercise database. As we add or retire exercises during the regular content reviews (we deprecate entries that turn out to be duplicates, dangerous, or poorly defined), the counts shift. Treat the absolute numbers as a snapshot of current coverage, not a permanent property of the muscle or equipment.
How this page is generated
Every refresh of the underlying database triggers a regeneration of this page during the build process. Counts are computed by joining the exercises table against the muscles and equipment reference tables on their respective primary-muscle and primary-equipment foreign keys, then aggregating with COUNT(*) and ordering descending. No human curates this ranking; it is a pure SQL aggregate over the current corpus, deterministically reproducible from the database file.
That choice is deliberate. Rankings curated by editors are vulnerable to editorial bias and to going stale between updates. Rankings computed from the live data automatically track corpus changes and can be audited end-to-end: the SQL is documented on the methodology page, the data sources are open, and you can reproduce the numbers locally with the open exports.
