If you are someone familiar with the various kinds of exercises, you must be aware of the benefits of crunches as well! If not, fret not, we got you covered here! Crunches are abdominal exercises that mainly target your core muscles. Those chiseled 6-packs you see and adore are all a result of rigorous training that involves a variety of crunches, such as bicycle crunches, oblique crunches, twisted crunches, swiss ball crunches, and v-sit crunches along with other exercises. They are great core workouts that strengthen your core muscles with your own body weight. These work by flexing and releasing your core abdominal muscles helping lose fat and build lean muscle mass alongside. While they don’t need any specific equipment and can be done anywhere anytime, you can do crunches with weights as well!

A 2020 study analyzed the gender-based preference for fitness exercises in North Americans. It was a mixed-method study that involved 342 males and 327 females from the US and Canada. Overall, both males and females reported crunches to be one of their preferred exercises. 64.2% of males and 52.3% of females reported having a high perceived self-efficacy. Only 12.87% of males expressed concerns about doing crunches, as they found them strenuous for their bodies.

Imogen Rose, a YouTuber, took the challenge of doing 200 crunches every day for 7 weeks to understand the changes that it can do to the body. She stated, “Day one: I underestimated how hard this was going to be. My abs were burning the whole way through these first 200 (i).” She admits to having followed a diet plan and also some cardio exercises. By day 5 it got easier to do the crunches and the body got used to it, and by day 7 the stomach had toned down visibly. She added, “My stomach looks noticeably flatter than before.”

Here Are Some Types Of Crunches, How To Do Them, And Their Benefits

1. The Basic Crunch:

The basic crunch is done by lying flat on your back with your knees bent and your hands behind your head, then you rise up to meet your pelvis using the shoulders and the core to maintain and propel you forward. Injuries can happen if you pull yourself forward on your neck or your head, using the strength of your hands. To avoid this risk, half crunches are a good place to start.

Beginners can start with 3 sets of 10-12 crunches daily to work on their abdominal muscles. Gradually increase the number of sets as per your comfort and goals.

2. Reverse Crunch:

Reverse crunches are done by lying flat on your back and putting your leg up at 90 degrees like you do while doing leg raises. Place your hands facing the ground on either side of your body. If you are starting out, you can place your hands behind your hip for added support. Then, using your core muscles in a controlled manner; pull up your legs and hips towards the ceiling while bringing your knees towards your chest. Then return to the start position. During this exercise, try not to use too much momentum or to do it so fast that you hurt yourself. Repeat as many times as you can.

3. Vertical Leg Crunch:

To do vertical leg crunches, lie flat on your back with your arms straight. Lift your legs together and heels facing the ceiling till it is directly above your hips. Then raise your arms to almost touching the feet with your fingers while pulling in your belly button to stabilize your position using your ab muscles. Your torso will look almost like a U shape. Breathe slowly, control the movement and repeat for 8-15 reps.

4. Long Arm Crunches:

To do this crunch, lie flat on your back with your knees propped up. If you want more resistance you can keep your legs straight out. Your arms should be above your head. Clasp them together. Using your core muscles, lift the upper part of your body. Make sure not to strain your neck. Repeat it 8-15 times.

5. Bicycle Crunch:

This workout not only worked the rectus abdominis but also works the upper abs. You can do this workout by lying flat on your back with your hands behind your head. Lift your knees off the floor towards your chest. First, rotate to the right and try to meet the left knee with the right elbow while you extend the right leg straight out, and then do the opposite side by trying to meet the right knee with the left elbow.

protip_icon Quick Tip
Bicycle crunches target not only your upper abdominal muscles but also your obliques, deep abs, hamstrings, and quads.

6. Double Crunches:

This is a basic crunch and reverse-crunch exercise together. Just lie on your back with your knees at a 90-degree angle and hands behind your head. Lift up your hips off the floor like in a crunch and lift up the shoulder blades off the floor like in a basic crunch. Try to squeeze the core and control the position. Then return to the start position.

Pros And Cons Of Doing Crunches
