Warm-Up

    A warm-up is light preparatory activity done before training to raise body temperature, prime the muscles and joints, and improve performance while reducing injury risk.

    Key facts

    • Raises body and muscle temperature.
    • Combines general cardio with movement-specific prep.
    • Improves performance and may reduce injury risk.
    • Ramp-up sets prepare you for heavy lifts.

    A good warm-up gradually readies your body for hard work. It usually starts with a few minutes of light cardio to raise your heart rate and temperature, followed by dynamic movements and lighter 'ramp-up' sets of the exercise you're about to perform.

    Warming up improves performance — muscles contract more efficiently when warm — and lets you rehearse technique before the load gets heavy. Static stretching is better saved for after training; before lifting, dynamic mobility and progressively heavier sets prepare you best.

    Frequently asked questions

    What's the best way to warm up before lifting?

    A few minutes of light cardio, some dynamic mobility, then progressively heavier ramp-up sets of your first exercise prepares both your body and your technique.

    Should I stretch before working out?

    Dynamic movement is better than long static stretches before training. Static stretching can briefly reduce strength, so it's usually best saved for after your session.
