Sometimes to change habits is sufficient for changing the whole lifestyle. How you look at your life, your body and your relationships can heal, empower and create the life you want.
Life is motion and you can feel every interaction with each person you meet. Learn to standup and be all you can be. You will see your life become what you want it to be.
The best solution of course is combining physical and mental improvements together with an empowerment plan and regular coaching. It will take into account your individual dreams and your assessment of your current situation in life.
