Inner muscle training

When I lie down my back, I can get up without rebound or guarding. 


but if I bend my knees, I cannot do that.


Some people can do both. How can I do that?

You know I go to the gym almost everyday as to shape up my body.

Maybe this is one of the best examples?


I am considering if I should have a personal trainer.
