How does crunches work on stomach

As one of the major core muscles, it provides stability for the body. If you build your rectus abdominis and have low enough body fat, you will see the six-pack abs that many people desire. Doing crunches correctly is harder than it looks.

Avoid these errors so they can be as effective as possible. This not only strains the neck, but it takes away from working your abs. You want to originate the movement in your abs, not from your head. To keep your neck in proper alignment and not moving, place your fist under your chin. The crunch is a subtle movement, lifting the shoulder blades just a few inches off the floor.

Jerking the shoulders up adds momentum and reduces the effectiveness of the exercise. It takes time to build strength in the abs, so it's best to take your time and do the move slowly rather than using momentum to get the body up.

It's easy to let your shoulders fall to the floor but a more effective approach is to keep the tension on the abs throughout the entire movement. You never want to completely relax the shoulders onto the floor. In the past, it was recommended to keep your back flat against the floor throughout the entire movement. Now it is believed it is better to keep a neutral spine.

That simply means your spine is in the strongest position to support you. A quick way to find it is to rock the pelvis back and then forward and then allow your pelvis to relax somewhere between those two extremes. If your back arches too much, that may mean your abs need time to build strength. Try propping your feet on a step or platform to give your back some support. If your goal is having flat abs or displaying your six-pack, the truth is that spot reduction just doesn't work.

In addition to building your six-pack muscles, you will need exercises that burn fat. When you exercise, your body draws energy from the entire body, not just the part you're working. High-intensity interval training has been shown to target belly fat. If you're new to HIIT training, start with beginner interval training and work your way up to more advanced training.

Lifting weights not only helps you lose body fat, but it can also specifically help you lose belly fat. Studies have shown that people who lift weights along with doing cardio have less belly fat than people who don't. Examine your diet. You've probably heard that flat abs are made in the kitchen and there's a reason for that saying. Often your diet is where you can make the most progress with losing belly fat.

But crunches don't address the fat itself. For that, you'll need to take a whole-body approach with cardio, diet and strength training. Once you're ready to work on muscle definition, it's important to remember that crunches alone can't create that toned look on your entire belly and waistline area.

The American Council on Fitness reminds core enthusiasts that the basic crunch only works on the rectus abdominis, also known as the "six-pack muscles.

Traditional crunches don't work your obliques, the muscles located at the sides of your torso. For those, you'll need to add variations like oblique crunches. Or you might opt for single exercises like the plank, which works more core muscles , along with back, shoulder and leg muscle groups.

While you can't magically target your belly fat alone by doing crunches for abs, working them into your fitness plan can be part of a whole-body, fat-burning strategy.

Mayo Clinic notes that muscles burn more calories at rest than fat cells do. While cardio and dietary changes are important for fat-burning, building muscle mass in your core will also contribute to overall increased metabolism. As a part of an overall strategy of increasing metabolism, Mayo Clinic recommends strength training at least twice a week.

Along with stomach crunches, equipment-free strength training can include pushups, squats and planks. Your abs are part of your core, which are the major muscle groups of your torso. That's why crunches, reverse crunches and other abdominal workouts can be a part of strengthening your core, as Harvard Health Publishing points out. The main drawback to situps is the possibility of lower back and neck injuries. By hooking your feet together during a situp, you can get a decent workout for your lower legs, too!

This intense muscle isolation makes them a popular exercise for people trying to get six-pack abs. This also makes them ideal for strengthening your core, which includes your lower back muscles and obliques.

Doing so can improve your balance and posture. Another consideration is your current fitness level. Crunches build up the abdominal muscles over time, but can cause significant back pain for beginners. Both situps and crunches are helpful for strengthening and developing core muscle.

Over time, a stronger core can also improve your posture and reduce your risk of back injuries later in life. However, neither exercise burns fat. The only way to attain a flat and muscular stomach is to combine these exercises with a healthy, low-calorie diet and regular fat-burning aerobic exercise.
