Both trainers say that how long it will take to see results varies from person to person, but in general, Smith says if you do crunches for 10 to 15 minutes at least three times a week, you'll likely notice a difference in four to six weeks.
Doing 100 crunches (proper crunches and not ``half-crunches'' or ``cheat crunches'') per day IS fairly effective in developing and strengthening your abdominal muscles, especially when paired with doing sit-ups, and side bends / oblique crunches to give your entire core set of muscles a good thorough workout.
Doing crunches every day may not allow your abdominal muscles sufficient recovery time, which could lead to fatigue or strain. Variability: It's beneficial to include a variety of exercises in your routine. Focusing solely on crunches can lead to muscle imbalances.
For Muscle: Do three to five sets of 15 to 20 reps. If needed, progress the crunch by holding a weight plate at your chest — as long as your form remains perfect. For Endurance: Once you're able to perform at least 20 reps per set with perfect form, aim for four to five sets of 25 to 35 clean reps each.
Crunches or other ab workouts help strengthen your core, but they won't get rid of belly fat. You can't target fat loss in one area. Focus on losing overall body fat with a balanced diet and eating fewer calories.
Aerobic exercise includes any activity that raises your heart rate such as walking, dancing, running or swimming. This can also include doing housework, gardening and playing with your children. Other types of exercise such as strength training, Pilates and yoga can also help you lose belly fat.
Unfortunately, sit-ups and crunches can't eliminate visceral fat directly. You can't reduce fat from specific parts of your body by exercising that body part; our bodies simply don't work that way. With sit-ups or other abdominal exercises, you're toning the abdominal muscles but not burning intra-abdominal fat.
If you can do 200 crunches in 10 minutes, that means you are burning around just 47 calories. That sucks, right? It's not impossible to do 200 crunches in 10 minutes. It's the rate of a moderate-intensity workout.

Go for abdomial muscles workout
So this three times in the week. Crunches and leg raises for three sets of 20 repetitions should be done. Also, do planks by holding your body in a push-up position on your elbows for 30 to 60 seconds for four sets.
The Bottom Line. So, what happens when you perform 100 squats every day? The short answer is amazing things. Your legs will become stronger and more defined, your butt will become firmer and more shapely, and your overall fitness level will improve.
Abdominal exercises such as crunches or sit-ups do not specifically burn belly fat, but they can help the belly appear flatter and more toned. Other exercises that can help whittle the waistline and tone up the belly include bicycles, planks, and side planks.
To burn off visceral fat, your first step is to include at least 30 minutes of aerobic exercise or cardio into your daily routine. Studies show that aerobic exercises for belly fat help reduce belly fat and liver fat. Some great cardio of aerobic exercises for belly fat include: Walking, especially at a quick pace.
Sit-ups can give you firmer abs, toning your stomach and making you sweat. Beginners should start with two or three sets of eight to 12 repetitions. How many sit-ups a day should you work up to? Once you've strengthened your lower back, you may be able to handle 15 to 25 repetitions for each set.
It's a lot and it tires out the core muscles which means your form can deteriorate, putting your lower back and neck at risk of injury. That said, I love this exercise as it targets all of the major muscles in your core, but doing fewer reps is enough to reap the rewards.
Although crunches help build muscle, they don't burn a lot of calories. It's nearly impossible to lose weight or belly fat using crunches alone.
The Sit-Up Myth
Sit-ups are a common physical activity that women and men perform to help strengthen abdominal muscles. In reality, classic sit-ups are proven to be ineffective at reducing belly fat and increasing core strength. Additionally, research shows crunches can even be bad for the spine.
With consistent effort and proper form, planks can help reduce belly fat significantly, making you look leaner in no time!
