This three part class consists of 40 minutes of low impact aerobics, with a long gentle warm-up leading up to more vigorous low impact movement to music, followed by a cool down to bring heart rates down gradually. Next is 30 minutes of resistance training to build strength and improve muscular endurance, using weights and a variety of resistance equipment. Finally, 20 minutes of stretching and relaxation help to improve flexibility and joint mobility, with emphasis on breathing to relax and release tension.
