If you are looking to tighten up your tummy, there are few exercises as simple and effective as a plank.
Not to be confused with the strange and lazy planking craze that took the internet by storm in 2011, planks require some serious strength.
Holding one's entire body weight with your hands and feet might sound simple, but holding the pose for even a minute can result in a serious sweat session — not to mention it'll also cause your body to tremble!
But the longer you can hold it, the better it will be for you. According to Men's Fitness, holding a plank builds muscles in your back and abdominals, protecting you from injury and burning fat at the same time.
And performing planks can also help correct spinal curving in scoliosis patients, The Wall Street Journal reports. In fact, 17-year-old Gabi Ury, who holds the record for holding the longest plank at 1 hour, 20 minutes and 5 seconds, lives with scoliosis and is missing muscles in her calfs, glutes and parts of her abs.
So no excuses, get planking to start building your muscles. Below, we list 20 plank moves to help get you started and go to the extreme.
