In order to keep balance you must keep moving.
Basic Stretching facts
We loose 10% of our range of motion for every 10 years we age, unless we take an active role in maintaining or improving our flexibility.
Many factors affect flexibility such as: age, dehydration, adhesions, lack of elasticity of connective tissues in muscles or joints, muscle tension, gender, hormones, length of ligaments or joints, lack of coordination and movement, inflammation, pain, fear, body mass, temperature, medication, training, vocation, postural misalignment, repetitive movements and more…
Flexibility must be balanced with strength to be fully functional.
