How effective are abdominal crunches?
Like situps, crunches help you build muscle. But unlike situps, they work only the abdominal muscles. 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.
How many sets of abdominal crunches should I do?
How many crunches should an individual do every day? 10-12 repetitions and three sets of crunches will be good enough. In addition, you may do three sets of two or three variations to engage the other muscles in the stomach.
Why do I shake when doing crunches?
If your body shakes the first time you do crunches, there’s no need to panic. This quivering is your body’s natural reaction to the lengthening and shortening of your muscles. You’re putting demands on your abdominal muscles that they’re not used to.
Are planks better than crunches?
While the humble crunch can work wonders for your core, the plank provides optimal results when it comes to aiding sports performance, rehab and general fitness. So, if you really want to maximize the benefits of your core training the increased muscle activation you get with a plank means it’s the way to go.
Is my core weak?
Lyons suggests two quick at-home tests to determine whether or not your core is weak. “You should be able to hold a hollow hold—your low back is pressed into floor, legs and arms hovering in the air, and core ignited—for at least 10 seconds. And you should be able to hold a plank for at least 50 seconds,” she says.
Is shaking after a workout good?

Are planks enough for abs?
A proper plank engages your abs, yes, but also your shoulders, back, glutes and quads. Planks are billed as the must-do ab move if you’re serious about developing a strong core.
Why do I shake when I do the plank?
“Shaking or quivering during a plank is totally normal. This just means you’re pushing the muscle contraction to its limits and challenging its endurance capacity,” says David Jou, PT, DPT, co-founder of Motivny in New York City. The same goes for shaking during other exercises, according to Dr. Jou.
