Some recent medical studies have shown a new idea regarding senior’s and exercise. The most common exercises advised were walking (jogging), biking and swimming. But there is now indications that resistance training (weight training) may have a better effect in the long term abilities as we age. These studies indicate that seniors loose muscle tissue at a much faster pace as we age, and that the regaining of that muscle tissue takes much longer. Also they advise seniors to have 1 gram of protein per kilogram of weight each day. To determine your weight in kilograms divide your weight in ponds by 2.205. An example would be a person weights 160 lbs. to find that kilogram weight 160 divide by 2.205 + 72.6 kilograms. That should ingest 1 gram of protein for each kilogram of weight, in this case it would be 73 grams of protein per day.
