Everyone tells us to stretch before exercise, but does it actually help improve performance and recovery?

Turns out that it depends on the type of sport—and the person. Some sports, like figure skating or snowboarding, benefit from a good limbering up; those that use explosive muscle power, like the bobsleigh, are hindered. Either way, there's some benefit to be had from a warm up—even if it doesn't involve gruelling stretches. This ASAP Science video explains why that's the case. [ASAP ScienceScience]
