Document Summary

Most recently, post workout stretch is best. Before workout, muscles slacken, and thus are weaker. Flexibility is the ability to move a joint through its normal range of motion. Looking to modify a muscle"s range of elasticity. Joint structure (no altering possible): 50% resistance comes from this. Muscle tissue fascia: the connective tissue reduces flexibility: 40% resistance. Ligaments (bone to bone) and tendons (bone to muscle) also limit flexibility: 10% of resistance. Skin: has some elasticity and prevents extreme movement. Most we can do is alter muscle tissue fascia. Types of flexibility: ballistic stretching: muscle spindles contract suddenly and forcefully. Not good: static stretching: slow, gradual stretching of gto. Frequency: min 2-3 days/week, max every day. Contract-relax method, contracting muscle prior to stretching helps muscle to stretch further. A slipped disc won"t only hurt your back, it will mess with the surrounding muscles. For our back, we want to avoid over-flexion or over extension.
