Train the force–velocity curve.

Force Curve is built around Heavy, Power, and Speed — plus Cardio — so every session has a clear quality. Log sets, track outdoor GPS, ask Siri between sets, and keep your data in your own iCloud.

Built for the curve

One quality at a time — or concurrent when you need the full H → P → S day.

H

Heavy

Max strength. High load, low velocity, progressive overload.

P

Power

Intent and bar speed — Explosive emphasis without confusing it with cardio.

S

Speed

Velocity and rate of force. Separate from Cardio so training stays clear.

C

Cardio

Manual or GPS for run / bike / swim, plus machines like elliptical via Log Manually.

Hands-free with Siri

Start a quality, log a set, or finish — without unlocking the phone.

Try: “Hey Siri, start Heavy in Force Curve” · “Log a set of Back Squat in Force Curve” · “End workout in Force Curve”

Private by design

No Force Curve account. Workouts sync through your iCloud (CloudKit) across iPhone, Mac, and Apple Watch when you’re signed in with the same Apple ID.
