You must prepare yourself ready to have core abdominal training, if you wish to flatten your abs and build up 6 pack abs. The path which you have selected to carry on your agenda must be the least hazardous and the easiest.
You can lift the legs above the ground. Then your lower part of the body should be kept at right angles. This is also a method of doing crunches. This is cited as the safest manner to execute crunches.
The least hazardous abdominal exercises are found based on the work to contraction ratios. The best exercise for the rectus abdominus (six pack abs) according to their measures was the one that worked the abdominal muscles really tough, but put the least force on the joints of the lower back.
Many of the frequent abdominal exercises have been tested to find out their work compression indices. The maximum has been scored by the exercise in which you lift your legs and keep your hips at 90 degree. This is because the exercise puts more pressure on the abdominal muscles than on the lower back.
According to the previous inquiry, the exercise which worked the hardest on the abdominal muscle is the hanging double straight leg rises. In this you need to hang from a bar and tend to lift both of your feet in front of you.
This would appear to be the best exercise for working the stomach because it works the abs harder than crunches, but the disadvantage of this exercise is that it also puts the most force on the lower back.
Why do hanging leg lifts put so much pressure on the back?
Your lower back faces the challenge and experiences the force, whenever you move your legs. This is not a risky thing if you are flexible enough and strong enough to control the movements of your pelvis, lower back and legs.
In fact being able to hold your pelvis and legs is essential for anyone who is looking to improve their core strength and function and is even more important for anyone involved in athletics, recreationally or competitively.
The hip flexor is the muscle which helps you in bending your hips and moving your thighs closer to your chest and this muscle is attached to the spine. Therefore, when the muscle is at work and is tight, you tend to pull the spine. The force on the lower back is due to the inflexibility and the weakness of the abdominal muscles.
More force is given to the lower back joints, when it is arched. So to get freed from the pressure and the pain lift your feet off the land and keep the hips at right angle. Benefits and risks for every exercise vary. But their pros and cons are sure to occur. You must select your own exercising routine based on your body’s fitness levels.
