Flexible, limber, pliant refer to that which bends easily. Flexible refers to that which is capable of being bent and adds sometimes the idea of compressibility or expansibility: a flexible piece of rubber hose. Limber is especially applied to the body to refer to ease of movement; it resembles flexible except that there is an idea of even greater ease in bending: a limber dancer. Pliant stresses an inherent quality or tendency to bend that does not require force or pressure from the outside; it may mean merely adaptable or may have a derogatory sense: a pliant character.

Something that is flexible is easily bent without breaking.

The word flexible can refer to bendable physical objects or to intangibles like a person's mind, which can be changed. It can even refer to work environments that can adapt schedules and benefits to fit a worker's individual needs. Being physically flexible usually means good health, with no pain in movement. In all, it's great to be flexible, to be able to bend without breaking and bounce back, ready to keep going.
