ACHY? Try a “step stretch”

As we spend more time indoors, production of painkilling endorphins begins to drop, leaving 55% of us feeling achy right now. But according to British researchers, deeply stretching your calf muscles for 30 seconds can increase flexibility for 90 minutes—and signal your brain to release endorphins. To do: Rest the pads of your feet on a step and let your heels drop or pull your toes toward you while sitting on the floor.
