Human trunk support

You strengthen an abdominal muscle, the back by bodily sensation training, and do you not tighten a presumptuous stomach?

The stomach is tightened when I strengthen an abdominal muscle, the back and leads to low back pain improvement.

I maintain a posture for 15 seconds, and this application takes a break for ten seconds.

I perform this three sets.

There is it more strictly if taken the ease for this posture when I put up one leg this time and train.

As you are free, you have you confirm a flow, and please try it once.

※Attention
・With some smartphones, a vibe does not work. As it is out of control of Android, I cannot support it.
・I use the net communication only by an advertisement, operation situation confirmation. I do not use it at all elsewhere.
