How to do Oblique Crunches with Bent Knee Leg Lift

01
Setup
Lie on your back with your knees bent, feet flat on the floor. Extend one arm straight overhead, and place your other hand gently behind your head.
02
Setup
Shift your hips slightly towards the side of the arm extended overhead, then let both knees fall to the opposite side, keeping them stacked.
03
Exhale as you simultaneously lift your torso off the ground, crunching your shoulder towards your opposite hip, and lift your top knee towards your chest.
04
Focus on contracting your obliques on the side you are crunching towards, imagining bringing your rib cage closer to your hip bone.
05
Inhale as you slowly lower your torso and leg back to the starting position with control, resisting gravity.
06
Complete all repetitions on one side before switching to the other side to maintain balance and focus on the target muscle.

Tips

Maintain a controlled movement throughout the exercise, avoiding momentum to maximize oblique activation and prevent injury.
Keep your neck relaxed; the hand behind your head is for support only, not to pull your head up, which can strain your cervical spine.
Focus on the mind-muscle connection, actively squeezing your obliques during both the crunch and the leg lift to enhance effectiveness.
Ensure your lower back remains pressed into the floor as much as possible to protect your spine and maintain core engagement.

Common mistakes

Using momentum instead of muscle engagement: Avoid swinging your body up; instead, perform a slow, controlled lift by actively engaging your obliques.
Pulling on the neck: Do not yank your head forward with your hand; gently support your head and lead the movement with your chest and shoulders.
Not fully engaging the obliques: Ensure you are actively trying to bring your rib cage towards your hip bone on the working side, rather than just crunching straight up, to maximize oblique recruitment.
