What are oblique crunches?

Oblique crunches are a bodyweight abs exercise. They’re similar to a conventional crunch but they involve a twisting movement.

What muscles do oblique crunches work?

Oblique crunches are an isolation move, so they only work one muscle group. They predominantly target your side abs, which are also known as your obliques. But you will also get muscle activation across the rest of the abdominals.

How to do oblique crunches

• Lie on your back with your knees bent.
• Bend your arms to place your fingertips to your temples.
• Using your abs muscles, crunch up to begin to lift your shoulders off the floor. As you do so, twist to one side to bring one elbow towards the opposite knee. They won’t actually touch but that’s the direction you’re moving in.
• Lower slowly to the start and repeat.

What’s are the most common oblique crunches mistakes?

It’s easy to almost entirely miss out on abs muscle activation. You do that if you yank your neck off the floor. So try to keep a light contact with your fingertips on your temples. And try to relax your neck as much as possible.

The best oblique crunches alternative exercises

Dumbbell side bend

Equipment needed: Dumbbell
Why do it: This is a great alternative to oblique crunches because it is easy to execute.
How to do it: Hold a dumbbell in one hand by your side. Place the fingers on your free hand to your temples. Bend to the side holding the dumbbell. But make sure you move in a controlled way. Don’t let the dumbbell pull you further than you can control. Once you have reached your end range, return to the start. Complete all of your reps on one side then repeat on the other.

Equipment needed: Pull-up bar
Why do it: The benefit you get with this hanging knee raise variation that you don’t get with oblique crunches is that it develops your grip strength.
How to do it: Hang from a bar with your arms straight. Bend your knees and raise your thighs. As you do so, twist to one side to contract your obliques. Slowly return to the start and repeat, this time twisting to the other side.

Why do it: When you do oblique crunches your abs may not get much time under tension in the set. Your abs are under constant tension with this move and that’s what makes it so effective.
How to do it: Start with your knees bent, your feet on the floor and your fingers to your temples. Bring one elbow and the opposite knee in to meet each other while straightening your other leg. Then bring the knee on your straight leg in to your opposite elbow. Repeat that alternating movement for the duration of the set.

Alternating heel touch

Equipment needed: Bodyweight
Why do it: This alternative to oblique crunches looks really easy but it is deceptively tough. It’s simple but effective.
How to do it: Lie on the floor on your back with your knees bent and your arms by your sides. Slightly raise your head and shoulders off the floor. Reach to touch your heel with your fingertips. Then reach to touch your other heel with your opposite hand. Alternate sides for the rest of the set.
