The Right Way to Warm-Up
You've heard it for years: "Stretch before you sweat."
As it turns out, your PE teacher was wrong!
When researchers at the University of Zagreb in Croatia looked at more than 40 years of studies, they found that static stretching, like touching your toes and holding, reduces strength by more than 5 percent. Explosive muscular performance, which you use during box jumps or doling out a hard tennis serve, by as much as 3 percent. What gives?
"Static stretching briefly loosens tendons, so the time needed to transfer energy to initiate movement takes longer," Says study author Goran Markovic, PH. D.
P2 Personal Training says to swap old-school stretches for dynamic moves like jumping jacks and high kicks, which activate the muscles you'll use later in your workout.
