The rectus abdominis, sometimes referred to as the “abdominals,” are the abdominal muscles located at the front of your body. Crunches are a core workout that’s great for building a strong core.
Crunches also engage the obliques, as well as the muscles in the pelvis, lower back, and hips, which are part of your core.
This well-known workout has several versions, each focusing on a different section of your abs. You need to learn how to do crunches safely and effectively if you want to get the most out of them and avoid injury. The pros and cons of each type of crunch are listed below, along with professional advice on how to do the most popular varieties safely.
Types of crunches
There are many varieties of crunches to choose from. Starting with the four basic types listed below can be helpful and may seem less daunting because of it. Each focuses on certain abdominal muscles:
- Simple basic crunches: Focus on your rectus abdominis
- Bicycle squeaks: Target your rectus abdominis. Oblique muscles by doing only bicycle crunches.
- Reverse crunches: Target the rectus abdominis, transverse abs, and obliques with reverse crunches.
- Crossover crunches or cross crunches: focus on the rectus abdominis and oblique muscles.
Basic crunches:
My best advice for this kind of crunch is to not strain your neck or pull it towards your chest. Put your head on your hands and visualize yourself holding a tennis ball between your chin and your chest to avoid this. Instead of focusing on your legs, push your torso skyward.
- Lie flat on your back with your feet hip-width apart.
- Your elbows should be apart as you bend your knees and place your fingers behind your ears.
- Take a long breath.
- Exhale, tighten your abdominal muscles and raise your head, neck and shoulders to the sky.
- Take a deep breath, then reset your posture.
- For five rounds, repeat 10 to 12 times.
bicycle squeaks
You should “avoid squeezing your fingers behind your head” when doing bike crunches. Before picking up the tempo, make sure you have the movement in place. Think big: Focus on fully extending your leg and maintaining a wide-open elbow position throughout each rep.
- Lie on your back with your elbows wide open and your fingers behind your ears. Bring both legs into a table pose while maintaining a hip-width separation by contracting your abs (your knees should be directly over your hips and your ankles should be in line with the knees.
- Rotate your body so that your left elbow touches your right knee while bringing your right knee in towards your chest and lifting your shoulder blades off the ground at the same time. Stretch your left leg while keeping it above the floor.
- Switch sides while maintaining a wide-open elbow position and pressing your navel against your spine. It is a repetition.
- For five rounds, repeat 10 to 12 times.
Reverse crunches
Reverse crunches can be done well by “going slow and controlling each stride with your abs.” Also, try not to roll too far. In the upstroke, only your tailbone and hips should be lifted off the mat. When your back begins to sag further from the ground, stop.
- When you’re on your back, place your feet hip-width apart on the floor. Maintain a relaxed posture with your arms at your sides. Keeping your legs hip-width apart, steadily raise them to tabletop position by contracting your abs (your knees should be directly over your hips and your ankles should be in line with the knees. C This is where it all begins Neutral spinal alignment with a small natural curvature in the lower back Take a long breath.
- Exhale as you curl your hips and knees toward your chest while contracting your abs; as you curl, your hips should lift off the surface. Maintain a 90 degree angle between your knees. Maintain a natural swing in your neck and loosen your shoulders.
- With your hips back on the mat and your knees over your hips, still bent at 90 degrees, gently return to the starting position. Inspire.
- For five rounds, repeat 10 to 12 times.
Cross Crunch
My best advice for this kind of side crunch is to visualize a tennis ball between your chin and your chest instead of letting your neck do the work. On the way up, be sure to fully engage your abs and on the way down, be sure to control the movement. Put your attention on the actual timing of your breathing.
- Lie flat on your back with your feet hip-width apart. Your elbows should be apart as you bend your knees and place your fingers behind your ears. Place your left ankle on your right knee, crossing your right leg over your left. Take a long breath.
- Exhale as you contract your abs and raise your upper body off the mat so your right elbow is aligned with your raised left knee. Tighten your abs and twist your body to the left.
- As you carefully lower your upper body to the mat, breathe.
- For five rounds, repeat 10 to 12 times.
Benefits of crunches
Improved posture and stronger core
Crunches target a variety of muscles in your core or torso, much like any core workout. They help teach these muscles to work together more effectively, which can improve your stability and balance.
Strengthening your abdominal muscles will help you feel more comfortable doing everyday tasks and exercising. Your body uses your core muscles the most during many physical activities, including sitting, walking, lifting weights, and playing sports. Working on your core strength can also help you stand and sit more upright, which can lessen any back pain you may be experiencing and prevent your muscles from tiring quickly.
You will expend energy
The question of how many calories crunches burn is often asked, but the answer is elusive. Your age, level of muscle mass, general physical condition, and length of sit-ups will all impact the number of calories you can expect to burn. Crunches don’t burn as many calories as aerobic activities (like jogging), but they still have some calorie-burning potential.
There is no equipment required
Crunches have a major advantage in that no additional equipment is required; all you need is a small area of ground to lay down on. This implies that you can accomplish things without difficulty wherever you are, be it at home, in a hotel or elsewhere.
Reduced back pain
Your risk of lower back discomfort and muscle injury may increase if your abdominal muscles are weak. Exercises like crunches can strengthen them, which can help you avoid injury, relieve back discomfort, and speed up the healing process after a back injury. However, before doing sit-ups if you have a back or neck problem, consult a doctor. If they are sure about you, they can check. To avoid aggravating an injury, it is also advisable to consult a personal trainer to ensure that you are performing the action correctly.
It is recommended to take joint support for flexibility bones.
Side effects of crunches
Only your core is the focus
Crunches engage a limited set of muscles, but they’re great for strengthening your core. You need to use other workouts besides cardio to get a full body workout. Recommendations say you should get at least 150 minutes of moderate-intensity activity per week, including strengthening exercises on at least two days.
It can cause injury
Your spine flexes when you contract, which adds pressure there. Crunches can put extra strain on your neck and spine if you already have back pain or aren’t doing the exercise correctly. This could lead to a new injury. This also implies that if you are over 65 and have a history of back or neck injuries, crunches may not be the best exercise for you. Before doing sit-ups, consult a doctor and consult a personal trainer if you are unsure.
When to consult a doctor
If you have neck or back problems, avoid doing sit-ups until you’ve spoken to a doctor about their safety. After the first trimester of pregnancy or as soon as your belly starts to “show”, you must avoid cracking; however, if you are pregnant, consult a doctor for more specific advice.
If abs are causing pain in any part of your body, stop training and see a doctor as soon as possible.
If you experience any of the following symptoms after doing sit-ups, call an ambulance or go to the emergency room right away:
severe back pain, difficulty with your buttocks or genitals, and numbness and weakness in your legs deciding when to poop or urinate.
Carry
The crunch is often considered the ideal workout for the abs. However, it is not a functional core exercise, as it only works the abdominal muscles.
Crunches may not be for everyone as they can lead to neck and back pain. Instead, try other exercises, such as the bird dog or mountain climber. Not only do these exercises work many core muscles, but they also reduce pressure on your spine.
Consult a personal trainer if you want to do crunches. They can provide guidance, adjustments, and substitutes to keep you safe while helping you get the ideal core exercise.
