An exercise specialist helps clients plan and carry out fitness regimens in a variety of settings. These specialized trainers often work in a hospital, rehab facility, or another clinical setting. You can also find employment at health clubs and gyms. Your responsibilities in this career include monitoring a client or patient's exercise and teaching them the proper techniques so that they can carry on with their exercise program after leaving the facility. An exercise specialist may teach methods to increase strength and cardiovascular fitness, but you should also focus on things such as flexibility, balance, and functional performance.
