The ab exercises need to get more difficult as the body training progresses. The best sit ups for medium difficulty level may be performed on a Swiss ball or an incline bench. Other people put a weight on their chest while exercising to increase the difficulty. Once you no longer have problems performing an exercise, you need to move on the superior training level. Use heavier weights or change the legs position when performing the sit ups. You’ll see for yourself how hard it becomes to do the sit ups with the legs lifted in the air.
Pedaling is also possible while doing sit ups, but the advanced will handle such exercises most of the times. Leg movements with the right knee touching the left elbow and the left knee the right elbow increase the efficiency of the best sit ups. There are a few tips and tricks designed to boost the efficiency of the best sit ups. For instance, you should always keep the abdominal muscles slightly tight while sitting up so as to improve the training. Once you get in the maximum raised position you should hold it for a second before bringing the torso back on the ground.
Watch the hands position. The exercises are easier when you hold them behind the head, but the best sit up are those that are performed without any head support. From behind the head, you can move the hands to the sides, then on the chest and finally on the sides when the time is right. The sit ups also work in combination with twisting crunches for the training of the waist muscles or the obliques. Raise the shoulder blades from the ground and instead of bringing them towards a vertical position, do a twist to the side. This should allow you to work out all the abdominal muscles in one.
