Setup
- Lie flat on your back on a mat with your legs bent at a 90-degree angle in a tabletop position.
- Place your hands flat by your sides or tucked slightly under your glutes to help stabilize your pelvis.
- Press your lower back firmly into the floor to engage your core and eliminate any arch in your spine.
How to do it
- Inhale and slowly extend your legs forward at a 45-degree angle while simultaneously pulling your toes back toward your shins.
- Exhale as you reach full extension, squeezing your quadriceps and bracing your abdominals tightly.
- Pause for one second at the peak of the movement, ensuring your legs are straight and toes are flexed hard.
- Slowly return your legs to the starting tabletop position using a controlled 2-second eccentric tempo.
Form checklist
- Keep your lower back glued to the floor throughout the entire movement.
- Maintain active toe flexion (pulling toes toward shins) during the extension phase.
- Ensure the movement is driven by the knees and hips, not by swinging the legs.
- Keep your head and neck relaxed on the mat to avoid strain.
Pro tips
- Focus on the mind-muscle connection by visualizing your kneecaps pulling upward toward your hips as you straighten your legs.
- Imagine you are pushing your heels against an invisible wall while pulling your toes back to maximize tension in the quads and tibialis anterior.
Make it harder
- Lower the angle of your leg extension closer to the floor to significantly increase the demand on your lower abdominals.
- Perform the exercise with your head and shoulder blades lifted off the mat in a 'hollow body' position to increase upper-core engagement.
