Alternate Toe Tap Leg Lift

  • Beginner
  • Isolation

This exercise isolates the lower abdominals and hip flexors through a controlled leg raise while engaging the obliques via a cross-body reach. It is excellent for building foundational core strength and improving coordination between the upper and lower body.

Setup

  1. Lie flat on your back on a mat with your legs fully extended.
  2. Place your arms by your sides or slightly overhead for a greater challenge.
  3. Engage your core by pulling your navel toward your spine and pressing your lower back firmly into the floor.

How to do it

  1. Exhale as you lift one leg toward the ceiling while simultaneously reaching the opposite hand toward that foot, lifting your shoulder blade off the mat.
  2. Inhale as you slowly lower both the leg and arm back to the starting position with a controlled 2-second tempo.
  3. Repeat the movement on the opposite side, alternating legs and arms for each repetition.
  4. Maintain a steady rhythm, ensuring your lower back never arches away from the floor.

Form checklist

  • Keep your lower back glued to the mat throughout the entire range of motion.
  • Ensure the leg remains as straight as possible to maximize quadriceps and hip flexor engagement.
  • Lift your shoulder blade completely off the floor during the reach to engage the obliques.
  • Avoid using momentum or swinging the leg; move with deliberate control.

Pro tips

  • Focus on 'crunching' your ribs toward your hips as you reach for your toe to maximize upper and lower abdominal compression.
  • Pause for a split second at the peak of the movement to emphasize the contraction of the rectus abdominis.

Make it harder

  • Keep both legs hovering 2-3 inches off the ground throughout the entire set instead of resting the non-working leg on the floor.
  • Hold a light dumbbell or medicine ball in your reaching hand to increase the resistance on the core.
