Everyone gets bored of ab crunches and sit ups, and to be honest, they are a great workout. However, the plank exercise (a.k.a. isometric holds) can be a much more effective way of tightening your mid-section and toning your abs. Here’s a video tutorial on how to do the plank exercise:
Give it a try for a few weeks. It’s important to note that you probably won’t be able to do this hold for a minute at a time, at least, not right off the bat. So do the plank exercise as long as you can, three individual times in a workout. Take note of how long you can hold it for and chart your progress weekly. You’ll see that you can do the exercise for longer and longer each time!
