CD102.5’s Big Room is the spot to see intimate performances by the indie radio station’s top hitters, but soon it will also be the spot to get jamming in a different way. Jen Borman, local fitness guru and potential national star, and the radio station will present Rock Hard Workout Club starting Feb. 28. The Thursday night classes ($20 each) will feature an hour-long boot camp-style workout by Borman set to remixed music played live by DJ Lance. A “party” follows each class, complete with drinks — meaning organic smoothies — by artist and bartender Amandda Tirey Graham. Sign up or get more details here.
