Being i switched from the normal warmup(jog, static stretch, drills), the dynamic competition warmup is great. I just ran a 10.3ht 100m last saturdayat a development meet, first time i ran over the distance since early december, and i cruised.(there might have been a little wind behind me, not sure). this kind of warm up rocks! Id suggest it to every sprinter who does the "normal warmup". just thought i should share….sorry
