The only gym in Marshalltown, IA, the YMCA-YWCA is where it’s at! Body Pump and Body Combat group fitness classes are the best, but you need to buy a Class Pass to have access. Totally worth it, though! People actually wear nice workout gear to this gym, which is different than every other Y I have been to, so I felt a bit underdressed in my old T-shirts and shorts, but they did the job! Highly recommend if you are visiting or live in Marshalltown.
