Core-friendly desk rhythm

Rise & Reset

A core-friendly sit/stand timer with quick movement resets before posture breaks down.

Ready

Choose your tier

These are practical starting points, not medical rules. Switch earlier if symptoms show up.

Current rotation

Select a tier
00:00
Today's streak: 0 rotations

Begin with Beginner if your core or standing endurance is limited.

Hourly movement

Pick a reset that fits your next break

    Easy rule: move a little every hour and avoid staying locked in one posture.

    Switch sooner if you notice

    • Low-back tightness
    • Leaning into one hip
    • Neck or shoulder tension
    • Numbness, tingling, or foot fatigue
    • Slumping, fidgeting, or focus dropping

    What I verified and adjusted

    Rotate, do not just stand

    Standing is useful as a position change, but it is still static. The stronger evidence-based theme is to reduce long sedentary bouts and add brief movement.

    No magic ratio

    The app tiers are comfort-based starting points. There is not one universally proven sit/stand schedule for every body, desk, injury history, or task.

    Movement beats static endurance

    Prolonged standing can cause discomfort and fatigue too. Use standing, sitting, walking, stretches, and task changes as a rotation.

    Core training is separate

    Standing can demand more postural control than slumping in a chair, but it should not be treated as a real core-strength program.

    Use symptoms as guardrails

    Stop if a move causes pain, dizziness, numbness, or tingling. For injury, pregnancy, recent surgery, neurological symptoms, or heart/blood-pressure concerns, use clinician advice.
