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]
