About Strength Standards Calc
Strength Standards Calc is an independent site that publishes strength, body-composition and endurance standards drawn from named published sources, alongside a dated record of what fitness tracking apps charge. The standards are free; the app record is how the site pays for itself.
Why this site exists
Most standards pages online are a wall of numbers with no source and a supplement ad on top. This one names where every distribution and formula comes from, keeps the tools free, and puts the one honest commercial thing, an app's published price, in its own clearly labelled place.
Who it is for
A lifter checking whether a bench, squat or deadlift is average, good or advanced for their age, sex and bodyweight.
A runner converting a race time to a pace, a treadmill speed or a predicted finish at another distance.
Anyone reading a body-fat, FFMI, BMI, TDEE or macro figure and wanting to know where it sits, before deciding whether to pay for an app to track it.
What it does not do
- No supplement, drug or treatment is recommended or sold here.
- No figure is printed without the source it came from.
- No app price is estimated; if the app does not publish one, we say so.
What is on this site
1 guides, each with its sources on the page , 48 answers to the questions around them , and the comparison.
- Running pace conversion: Running pace conversion is the small, constant friction of training in mixed units: a plan in minutes per mile, a watch in kilometres, a treadmill in miles per hour.
Where the figures come from
Fitness tracking-app subscription prices (USD) verified against each app's own pricing page on 2026-09-10 by infra/ingest/hubs/strengthstandardscalc.com/ingest_vendors.py: every quoted figure re-fetched and matched verbatim (hash-pinned); category coverage evidenced by the app's live product page.
Who answers for it
