One of the advantages of weight lifting for senior citizens and/or obese senior citizens is the safety of the practice. No sudden moves, controlled weights and easy postures, this modality heads, by far, the ranking of what this specific group should do. Through a good physical evaluation, followed by adequate prescription, professional follow up, the benefits generated to heath and welfare are enormous. Usually when an obese elder shows up at the gym, he or she gets the same treatment and training program of a young individual. Aerobic exercises, medium and long periods are prescribed. There´s the first mistake, since obese elders, besides having an overweight due to their big fat mass, loose muscle mass quickly. Hence, those individuals have great difficulty in carrying their bodies through a long walk, climbing a flight of stairs or simply getting up. More than reducing their fat max they need to urgently gain muscle mass so they can have extra strength to carry, without so much suffering, their bodies during aerobic exercises. Gaining muscle mass has another great advantage that will be very important for the weigh loss. By gaining muscle mass, they increase their metabolic taxes, making them burn more calories, even when resting. Another great advantage of weight lifting for the obese elders is the protection the increase of muscle mass will generate to the motion system. Articulations and bones will be stronger and protected, baring the impact of a long walk, besides the stronger muscles giving better posture and balance. When this preparation is not done before or during aerobic activities we verify that the people who belong to this group perform such activities with suffering on their faces. Articulations hurt, bones ache, there is a huge general discomfort. If one wants to make the practice of physical exercises something enjoyable so people can do it regularly and incorporate it to their everyday habits, convincing someone who is suffering during practice is impossible. Pain or discomfort are signs something is not going the way it was supposed to go and something should be done so this individual, who needs those exercises so much, don´t look at it as a bad thing. Obesity grows in an enormous speed scaring health authorities. Obesity in elders is positively growing and those individual need special care and evaluation. Few gym are prepared to work with this public that, besides specific care, need patient professionals because going to the gym, for many of those individuals, consists in breaking a taboo. Gym everywhere, open your doors and minds, for more and more special groups are arriving by the day and, if taken good care of, they are clients for life!
