Are you looking to fire up those abs and take your core workouts up a notch? One move that delivers major toning and strength benefits is the criss-cross crunch exercise.

Also known as the bicycle crunch, this kinetic maneuver will have those abdominals burning in the best way possible. Learning proper criss-cross form will give you an intense core workout that challenges your midsection in a whole new way. Adding it to your routine can help sculpt those coveted abs and put you on track for a flatter belly.

This exercise can be done almost anywhere since you just need a soft surface like a mat or rug. The portability makes the criss-cross crunch easy to incorporate into ab routines at home, the gym, or on the go.

What muscles do the Criss Cross work?

The criss-cross exercise effectively trains both your rectus abdominis (the long vertical muscle) and obliques (side abdominal muscles). This dynamic combo of straight and lateral flexion creates an intense and thorough contraction.

By isolating these muscle groups from multiple angles, the criss-cross crunch chisels definition and builds foundational core strength. It’s one of the most comprehensive and challenging ab workouts out there.

How to Perform the Criss-Cross Crunch Exercise with Proper Form

To begin, lie down on your back on a soft surface like a mat or rug. Bend your knees so your feet are flat on the floor about hip distance apart.
Lace your fingers behind your head, being careful not to pull or strain your neck. Keep those elbows out wide to engage your core.
Now, exhale and lift your upper back off the floor, bringing your right elbow towards your left knee in a diagonal crunch.
Lower back down, then repeat on the other side, this time bringing your left elbow to your right knee.

That’s one rep! Continue alternating in a controlled manner, fully extending back down between each crunch.

Aim for 3 sets of 10-15 reps, breathing deeply throughout. Listen to your body and don’t push beyond your limits. You can watch the video on the Criss. We’ve also included a video, so you can really master the technique.

Pro Tips for Safe and Effective Criss-Cross Crunches

Here are some tips for getting the most burnout from this excellent cross-body ab exercise:

Go slow and controlled – no jerky momentum.
Keep knees bent at 90 degrees throughout.
Don’t strain your neck – go only as far as comfortable.
Tighten your core to get a deep contraction.
Exhale on the crunch, inhale on return.

With perfect form and consistency, the bicycle crunch will transform your core into a solid block of granite.

Avoid These Criss-Cross Crunch Mistakes

When performing the criss-cross crunch, there are some common form errors that can creep in. Being aware of these mistakes will help you maximize the effectiveness of this exercise and avoid injury.

One frequent issue is doing the crunches too quickly. The rapid momentum typically causes you to swing your bent leg or opposite arm rather than keeping the movement controlled. This significantly reduces tension on the ab muscles, limiting training benefits.

It’s crucial to do criss-cross crunches slowly and with precise form. No swinging or flailing! This focused control keeps those abs engaged the entire time.

Another key mistake is clasping your hands tightly behind your neck. Interlacing your fingers and pulling with your arms can yank your head up unnaturally. This risks injury to the delicate cervical vertebrae.

Instead, just lightly touch your fingertips to the back of your head without gripping. This still stabilizes without wrenching your neck.

Take Your Core Workout to the Next Level

Ready to feel the ab burn? Add the criss-cross crunch to your next core training session for serious results. With just a soft surface and good form, you can sculpt shredded abs and obliques in no time.
