Slow down there, Hercules! After 300 crunches, you might feel the burn in your abdominal muscles ?but you probably have not burned that many calories. The sad news is that crunches just aren’t a giant calorie-burner, particularly when compared to other physical activity.
However, if you are looking to build up a sweat and burn calories, cardiovascular activity that uses the large muscle groups to boost your heart rate is a significantly better use of your time.
Calories Burned Crunching
The average person completes about 30 crunches in a single minute, meaning it’ll take you about 10 minutes to complete your 300 crunches. Exactly how many calories you burn in this time depends in your size and the intensity of your crunches.
If you weigh 150 pounds and it is a moderate challenge to pump out your 300 crunches, expect to burn about 50 calories. Even when you’re employed at an intense speed to get the exercises done and it takes half the time, you may experience the identical caloric burn. You just worked harder for five minutes.
Heavier, deconditioned people will burn more calories doing 300 crunches. If you happen to weigh 250 pounds, for instance, you may burn 85 calories in 10 minutes of crunches working at a moderate intensity. If doing these crunches constitutes a vigorous intensity that leaves you sweaty and breathless, you may burn approximately 150 calories in the ten minutes.
Comparative Calorie Burns
The calories burned during 300 crunches is roughly equivalent to those burned in a 10-minute walk done at a 3 mph pace or 10 minutes of moderately intense jumping jacks. Running, cycling or swimming for 10 minutes burns significantly more calories.
69 calories in 10 minutes of moderately paced swimming
96 calories in 10 minutes of running at 5 mph (a 12-minute mile)
A 250-pound person burns:
190calories in 10 minutes of running at 6 mph (a ten-minute mile)
165 calories cycling at 12 mph

Crunches strengthen the muscles of your middle ?mostly the rectus abdominis, which forms the ridged six-pack envied by so many. The obliques on the sides of the waist assist each time you crunch. While working these muscles does not burn a variety of calories, it provides valuable strength to your core.
Performing 300 crunches in a row is likely to be excessive, as you’ll likely lose focus as you fatigue and, consequently, your form suffers. An excessive amount of repetition of the crunch movement may also lead to injury or pain within the neck or back. Instead of going for volume, go for quality. Move slowly through each crunch and feel the action of pulling your belly button in toward your spine as you lift your torso skyward.
An entire Core Routine

2. Bicycle Crunch
Lie in your back and lift your knees so your legs form a 90-degree angle at your hip and knee joints. With the hands gently resting behind the top, lift your torso and twist your right elbow to the left knee while you simultaneously extend the precise leg. Repeat in the alternative direction to complete one repetition. Complete 10 to 20 total repetitions to focus on your obliques.
3. Bird Dog
Position your body on all fours and extend your right arm forward, left leg back ?then switch. This move helps strengthen the stabilizing muscles of your spine. Aim for 10 to 15 repetitions.
