Turkish Get-ups - By the way, Turkish Get-ups work a bit more on all parts of the body, but they work better on the whole core area. The energy goes down from the lower part to the upper part of the body. By doing these, abs like do well and do not stress even on the spine.

Hanging leg raise - Hanging leg raise are better exercise in the coats of the total ups, because the torso is not stable and the body's poised is better than the pull ups. Doing this, the chest stays above and it spreads properly. To work better on the stomach, slow the speed of the hanging leg to slow down.

Split stance cable lift - Instead of bending, half-bending exercises are not only effective but also do not harm the spine. There is no need to put too much weight to do them. Split stance cable lift is also a similar exercise, which makes the core and lower half mussels more advantageous with sit-ups.

Crunches - The lack of standard floor is very effective in working in the stomach and gives more emphasis on the upper part of the stomach. For those who take fats in their chest and upper abdomen, it is a good way to shape upper stomachs that make more definition between stomach and chest.

Bicycle - Optional shoulders for knee bits all major abs work of muscles but focus more on obi objects. I usually recommend doing this exercise with extended legs in the air. When people cycle, they raise one of their legs and studies have shown that when one leg is stretched in that position the stomach is less busy because Hip Flexor is capable of managing the load without assistance.
Side crunch - This practice focuses on the obliques and does not require a higher range of speed. This exercise is best used to extract the obliques at the end of the workout.
Six inches - This practice is really contrary to the pane and becomes very difficult. People usually can take this position half the time of the pane. Be careful if you suffer in the lower part of the back; when planning to do this exercise and make small sets, focus on your form.
