Description

This exercise involves lying on your back and bringing your elbow to the opposite knee, alternating sides. It targets the abdominal muscles and helps improve core strength and stability.

How to Do Lying Elbow to Knee

1
Setup
Lie on your back on a mat with your knees bent, feet flat on the floor, and hands gently placed behind your head with elbows wide.
2
Setup
Engage your core to lift your head and shoulders slightly off the floor, bringing one knee up towards your chest so your shin is parallel to the floor.
3
Exhale as you simultaneously rotate your torso, bringing the opposite elbow towards the raised knee, aiming to lightly touch them together.
4
Inhale as you slowly extend the raised leg back towards the floor and return your torso to the starting position, maintaining tension in your core.
5
Immediately repeat the movement on the other side, bringing the other knee to your chest and the opposite elbow towards it, alternating sides throughout the set.

Tips

Focus on controlled rotation from your obliques rather than just swinging your arm or leg with momentum.
Keep your lower back pressed firmly into the floor throughout the entire movement to maximize core engagement and protect your spine.
Maintain wide elbows and avoid pulling on your neck; your hands are there for support, not to yank your head up.
Fully extend the non-working leg towards the floor without touching it to increase the challenge and range of motion.

Common Mistakes

×Using momentum instead of muscle engagement reduces effectiveness; slow down and focus on squeezing your obliques to perform each crunch.
×Pulling on your neck strains your cervical spine; keep your elbows wide and initiate the movement from your abdominal muscles.
×Lifting your lower back off the floor during the movement can cause discomfort; actively press your lumbar spine into the mat to maintain core stability.
