"Most people think we only have five senses, but we really have a six: our brain telling us where we are in space," says Gonzalez-Wallace.
To train and strengthen this sixth sense, "begin in the semi-lunge position and close your eyes. Then, at the same time, raise your left leg so your thigh is parallel with the floor and raise both of your arms out to the sides, but no higher than your shoulders. Then switch legs," he says. Repeat 8 times for each leg.
