What is the Strength Score?

Strength by muscle is a rough read on how your strength compares to your own bodyweight, one muscle region at a time — not a leaderboard, not a percentile, and never a 0–100 number to chase.

How it's worked out

For each muscle region, BulkForged checks every anchor lift you've trained for it. For each one, it takes your best-ever estimated one-rep max, divides it by the bodyweight you had logged closest to that session, and places the result in one of five bands: Starting out · Developing · Solid · Strong · Very strong. The lift and band you see is whichever one currently ranks you highest on its own bands — not just whichever raw number is biggest, since a 2× bodyweight leg press and a 1.2× bodyweight leg extension aren't on the same scale. The bands themselves are ones we wrote ourselves for your bodyweight, sex and age — not an outside certified standard.

Two things are true by design, not just by intention:

• Your band never goes backwards. For any one lift, the ratio we use is the best you've ever logged on it, and the bodyweight it divides by is the one you had at the time — not today's. Gaining weight on a bulk can't retroactively lower an old achievement, and a deload week can't dent it either. The number beside the band is that best-to-date ratio for whichever lift currently ranks you highest, so it can step down on a week a different lift takes the region — a 1.2× bodyweight leg extension can rank above a 2× bodyweight leg press without being the bigger number. That's the yardstick changing, not you getting weaker; the band itself still holds or rises.
• It's a rough guide, not a certified standard. We compare your best estimated 1RM against bands we wrote ourselves. Your own trend over time — whether that number is climbing — is what actually matters, more than which band you land in today.

Why some muscles say "we don't score this one"

We only score a region when we have a real anchor lift to benchmark it against and a band we're confident authoring. A handful of regions (neck, traps, forearms, and the inner-thigh/outer-hip muscles) don't have one yet, so their card row says so plainly instead of guessing. A region with an anchor lift but nothing logged for it yet reads "not enough data" — never a zero, which would read as "you're weak" when really it just means we haven't seen you train it.

Good to know

Your estimated one-rep max is tracked here the same way it's tracked everywhere else in BulkForged — it's useful information, but it's never treated as a real record. A band change never triggers a celebration; a true PR (a weight you actually lifted) is the only thing that does.
