Unfortunately when time comes to work out your abs you either don’t feel like doing it or you are simply to tired. You have to keep in mind the fact that you cant have a great body without strong and well shaped abs. In order to do so here are two exercises. The first one is the Decline crunch.
For this exercise you have to position yourself on a decline bench in such a way that your feet would be locked in at the top. Place your hands at the sides of your head or on your chest and raise your body up to a sitting position. You should do at least 4 sets with 30 to 50 reps. If you find it easy to do, you could hold a weight plate across your chest or simply make a twist bringing the left elbow to the right knee and vice-versa.
The second exercise is a little bit harder and it is called Knee/hip raise on parallel bar. This is mainly for working out your lower abs and it can be done on a knee raise apparatus. You need to support yourself on your elbows and lift your legs up until they are parallel with the ground, then slowly lower them. It is important to try not to swing and to keep your legs together while doing this exercise. 4 sets consisting of 20 to 30 reps will do just fine.
