Joint mobility is not the same thing as muscle flexibility, when exercising with
mobility drills you will not feel much of a stretch, were with flexibility you will feel the stretch this is important and shows your using the correct method.
A muscle doesn’t always have to be stretched to put a joint through its full
range of movement.
For example, you will achieve complete hip flexion if you
stand upright and bring your knee towards your chest.
Not much of a stretch, right? To stretch one of the muscles that oppose hip flex ion, the
hamstring, you will have to raise your leg with your knee straight or nearly
straight.
Its important to use both these methods in your training plan, as years and mileage pile calcium deposits on your joints and promote connective
tissue growth in all the wrong places. Your youthful well-oiled hinges come to a
grinding halt.
