Armed only with a laminated sign on a stick stuck into the sand and his Beach Yoga With Brad Facebook page, Brad Keimach offers light to moderate yoga at the shoreline each weekend for a suggested minimum donation of 10 bucks — which is, without a doubt, better than paying $19 to a stanky studio. Get your Namaste on with the seagulls and beach bums on a strip of sand just out from Barnard Way and Sea Colony Drive in Santa Monica. You'll enjoy your downward dog with seafoam tickling your heels. Keimach has taught yoga for 12 years (four on the beach), and student yogis can count on his encouraging, sunny disposition even when the weather is gray and cloudy. Oh, and he's conducted concerts with the New York Philharmonic at Carnegie Hall and studied under Leonard Bernstein. An educator, music historian and conductor, he says of the connection between yoga and composing and performing classical pieces, “Both require deep inner work, and both have an outer manifestation.” Thanks to Brad, your weekend workout's outer manifestation can get you a nice tan, too. bradkeimach.com.
