Description

A core exercise where you lie flat on your back, raise one leg to a 90-degree angle, then lower it back down. Alternate between legs.

How to Do Alternate Lying Floor Leg Raise

  1. 1
    Setup

    Lie flat on your back on the floor with your legs extended straight and together, and your arms resting by your sides with palms down.

  2. 2
    Setup

    Engage your core by pressing your lower back firmly into the floor; maintain this spinal position throughout the exercise.

  3. 3

    Exhale as you slowly raise one leg straight up towards the ceiling, keeping your knee as straight as possible, until your hip is flexed to approximately 90 degrees.

  4. 4

    Inhale and slowly lower the raised leg back down to the starting position with control, ensuring your heel gently touches the floor.

  5. 5

    Immediately repeat the movement with the opposite leg, alternating sides without resting the raised leg on the floor for extended periods.

Tips

  • Focus on maintaining a neutral spine by keeping your lower back pressed into the floor throughout the movement to protect your spine and maximize core engagement.
  • Control the lowering phase of the leg raise; don't let gravity just drop your leg, as this is where significant core stability is built.
  • Keep your non-working leg fully extended and grounded to provide a stable base and prevent compensatory movements from your hips or lower back.
  • Breathe deeply: Exhale as you lift the leg to engage your deep core muscles, and inhale as you lower it with control to maintain intra-abdominal pressure.

Common Mistakes

  • ×Arching the lower back indicates a lack of core engagement; fix this by actively pressing your lumbar spine into the floor before and during each leg raise.
  • ×Using momentum to swing the leg up reduces muscle activation; instead, perform the movement slowly and deliberately, focusing on the hip flexors and core.
  • ×Not fully extending the leg at the bottom compromises range of motion; ensure your foot gently touches the floor before initiating the next lift to get a full stretch.
