Physical activity practiced on a constant, regular basis contributes directly to the improvement of the structure and functions of different organs and body systems. It can also counteract the appearance of some anatomic and functional deterioration and contribute to the correction of certain deficiencies caused by improper conditions of life/work in people’s life. This study analyses two forms of physical exercise - Aerobic Step and Pilates. The goal of the study is to identify the effects of practicing Aerobic Step and Pilates exercises on the bodies of those who practice these forms of physical exercise. The hypothesis of the research is that practicing on constant/regular basis different types of aerobic exercises combined with efficient nutrition ensures optimum physical condition for everyday activities. The activity was carried out at the “Beauty Centre” aerobic hall from Timisoara, Romania. The study was carried out between February and May 2013 on a sample of 25 people subjected to anthropometric and functional measurements (size, weight, hip perimeter and body weight index, percentage of muscular tissue) both before (initial test - It) and after (final test - Ft) Aerobic Step and Pilates programmes. Results show the efficiency of these programmes as pointed out by the diminution of hip perimeter, by normal IMC, and by the increase of the active muscular tissues.
