How It Works

The Stack uses a combination of overspeed (lighter weights) and underspeed (heavier weights) swings in structured sessions prescribed by the app. The app tracks your speed data over time and adjusts the protocol to match your progression. Sessions are typically 15–20 minutes, 3x per week. The key difference from generic speed sticks is the structured programming — random swings don't build speed, progressive overload does.
