Description
An effective exercise that targets the oblique muscles by combining a side crunch with a bent knee leg lift.
How to Do Oblique Crunches with Bent Knee Leg Lift
- 1Setup
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.
- 2Setup
Shift your hips slightly towards the side of the arm extended overhead, then let both knees fall to the opposite side, keeping them stacked.
- 3
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.
- 4
Focus on contracting your obliques on the side you are crunching towards, imagining bringing your rib cage closer to your hip bone.
- 5
Inhale as you slowly lower your torso and leg back to the starting position with control, resisting gravity.
- 6
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.
