Make your obliques scream!

There is one exercise you don’t afford to miss if you want strong obliques.

I remember when I was in the French kayak team: this exercise was in the program almost in a daily basis, along with a few core movements.

The obliques are important muscles for power rotations of the torso (important in kayak!), but also for low spine stabilization.

The starting position could be a challenge for some people; if so, move to an easier exercise.
Lie on your back, legs straight; spread out the arms on both side for stabilization.
Lower your legs to one side, don’t let them drop, keep control; touch the floor, keep the legs straight all time, not easy but here is the real challenge: back up, still legs straight. Same thing on the other side.
Do not allow your torso move up on one side: keep the opposite shoulder in contact with the floor, so your obliques have to do the job for controlling the movement of the legs.
With this exercise, you'll get real obliques!
