The Butler Public Library, 218 N. McKean St., will host a tai chi demonstration with Bill Weber at 1 p.m. Tuesday, Nov. 15.

Join Weber, a certified tai chi instructor with more than 20 years experience, as he demonstrates various forms of tai chi.

Depending to a certain extent on the type of tai chi being practiced, it is considered very safe for people of all ages, as it exercises joints and muscles without placing too much stress on them. Therefore, this also makes tai chi an ideal form of exercise for people with either rheumatoid or osteoarthritis, as well as offering a wide range of other benefits.

Wear loose fitting clothing and athletic shoes. A participation waiver is required.
