When Tough Temple Barbell Club and CrossFit merged a year ago in Bethesda, CrossFit Bethesda was born. It’s a gym dedicated to activities such as weightlifting, gymnastics and kettlebell training. Before new clients get going on a fitness regime that’s all about a variety of intense exercises in a short period, they take a four- to six-week class that’s intended to work on form and build strength. Instructors teach each exercise with a focus on reducing the risk of injuries, and small classes boost camaraderie that extends to Facebook groups. One-on-one coaching is available.
