Fitness is not just aerobic activity . You must increase your muscle strength , too. As we age we are constantly losing muscle mass unless we are involved in activities that increase muscle mass. Consistency is the real key to success. No matter how hard you work out, you can sabotage all of your efforts with poor eating habits.
Water is very important to the proper functioning of the human body.
At all times of year, it is necessary to hydrate properly before, during and after a workout. If necessary, find a friend to join you while you are working out. It is often easier to stick to a workout plan if someone is doing it with you. That is probably the hardest thing to do. It takes up to six weeks to see any results.
