One of the most important aspects of a running program is consistent warm up.
As you may already know, warming up has shifted away from static stretching (reach and touch your toes for 30 seconds). This is because this kind of stretching is not sufficient at preparing the muscle tissue for repetitive contraction, and can actually lead to early fatiguing, loss of performance, and injury.
A good warm up routine includes dynamic stretching and muscle contraction in positions that mimic the mobility demands of the activity/ exercise. When going through your next running warm up, try these movements instead!
