Rick Robertson (foreground) leads Wayne Snively (back left), Linda DeLuca (back right) and his other students through the stroking bird's tail formation of Tai Chi during his class at the Newberry Springs Senior Center Wednesday.

Robertson, who was introduced to Tai Chi through classes at Barstow Community College, said he and his students go through a routine of 24 moves or postures a practice that became popular in the late 1950s about three times each class.

"We do a lot of striking moves, but we're doing it very slowly and rhythmically," Robertson said, adding that the martial art helps people maintain their strength, flexibility and balance. "We have a rule here: Nobody gets hurt."

Robertson's class is open to anyone and is at 6 p.m. Wednesdays at the Newberry Springs Senior Center. People are asked to give a $5 donation for each class they take. The senior center is located at 33383 Newberry Road.
