Endless crunches with or without equipment perfectly designed to build your abs and burn the tummy fat right off are certainly useful and should be incorporated into a comprehensive exercise routine.
On the other hand, there is one particular exercise that will tone your abs like no other.
Experienced gym-goers will hopefully agree that a plank is by far the most significant exercise when it comes to a good abs workout.
You goal should be to plank for up to 5 minutes a day. You should be planking in intervals and the sum of all intervals should equal 5 minutes.
The length of each interval depends on your fitness level, but this length should not concern you much. As long as you plank for 5 minutes a day, even if you have to rest 10 times to get there, you will have rock-hard abs without a single crunch!
Planking may seem easy but it’s a very demanding, total-body-exercise that engages all muscles, even those you never knew you had. It is one of the exercises regularly done in yoga classes as it strengthens the core muscles and makes you more equipped to do yoga postures that require a strong spine. By planking every day you are sure to improve your shape and see the first results within 4-6 weeks.
