There is no such thing as a foolproof way to losing weight, somewhere along the way, you will find that one or two of your most desired routine is actually wrong. But to limit your chance of incurring problems along the way, you may want to recognize the facts behind the routine that you would wish to try beforehand. Basically, this article will tackle about the 9 worst abs exercises you want to avoid. Read and digest the facts here one by one so you don’t end up getting something which will only harm you in the end.

1. Straight leg sit ups - The reason why this is a wrong kind of exercise movement is because of the shearing forces applied on the vertebrae as well as the spinal discs in case you have a flexed and rounded spine. By doing this, it is likely that the pressure is put in the small area of the disc area that can lead to small ruptures. The best thing that you can do to train abs is to opt for the brace and hollow method which is a basic isometric exercise which can strengthen the abs.
2. Straight legged raise – It is very likely that you come across this routine during high school gym class wherein someone is allowed to hold your feet while your knees are locked and the legs are fixed into the floor while you try to perform a wide number of situps. This is actually wrong because doing straight legged situps while your feet are stabilized will create an undue pressure within your lower spine and the movement you do in order to lift yourself from the floor may lead to injury.
3. Electronic ab stimulator – This can be found on many infomercials. In order to establish whether the use of this gadget is for real, many researches were done. In a nutshell, these researches found out that no significant improvements were seen and some people may find that they are already suffering from painful consequences because of too much use of this item. The machine is also available for a very high price!
4. Ab rocker – There are those people who actually get good results from the use of this tool. Do not be fooled though because research found out that this tool is not really helpful when it comes to the rectus abs and oblique abs workout.
   
5. Two-dumbbell side bends – Although this can target the obliques once done properly but you should understand that holding a couple of dumbbells actually negates resistance.
6. Hanging leg raises – You do this by hanging yourself from a bar while your back is arched then you try to raise your legs. The problem with this is that most of the stress is transferred into the hip flexors thus straining your spine in the end.
7. Neck barbell presses – you do this by raising the barbell and then lowered it while positioned at the back of your head hence leading for the head to protrude forward while the shoulders would retract back wards.
8. Poorly timed stretches - Although stretching is vital before and after exercises, wrongly done one can actually lead to muscle injury or worse, bone fracture so be very wary.
9. Crunches or sit-ups done while twisting the torso – these can lead to rupture discs because of the shearing forces exhausted into the spine.
