The leg raise exercise helps work and strengthen your lower abs which are typically a hard muscle to target.

Steps :

1.) Start off either lying on a flat bench or lying down on the floor, keeping your hands under your hips to support your back as this will be the starting position of the exercise.

2.) Once in position, keep your feet together and your toes pointed out, slowly raise your legs up towards the ceiling squeezing your ab muscles in the process.

3.) Continue on the motion upward while squeezing your lower abs then once you reach the top position, pause and hold for a count, then slowly return back to the starting position in a controlled manner.

Tips :

1.) You don't have to have a large range of motion for this exercise for it to be effective.
