What's new.

Whether a movement works one arm, one leg, or both is now part of the shared movement catalog that every tensr surface reads — the web, the app, and the command-line tools all agree on it, derived the same way. A movement’s default comes from its name (“One-Arm Row” reads as single-arm) plus a reviewed per-movement value, and your own choice always wins over either. It’s plumbing you won’t see directly, but it’s what lets a single-arm movement be counted and logged per side instead of lumped together. Nothing you authored before changes — anything without a side simply reads as “both.”

Your left side and your right side aren’t the same, and tensr finally stops treating them like they are. Laterality — whether a movement is done with the left limb, the right limb, or both — is now set on each movement itself, not flipped for the whole session at once. That means a single workout can hold a two-handed row, a left-only carry, and a right-only press, and each one is logged for exactly the side you trained. When you look back, your left and right show up as their own lines, so a lingering imbalance is something you can actually see instead of guess at. Older sessions keep working untouched — anything without a side set simply reads as “both,” the way it always did.
