It is important to understand that though it is all called "weightlifting" the amount of weight and intensity is dependent on the person doing it. Exercise at an older age is simply adjusted according to your abilities, needs and concerns. Part of learning to strength train is learning to move well and move naturally. One of the most important elements of exercise as we get older is the development of balance and stability throughout our entire body. This means balance when we stand, walk or kneel. It also means the ability to move comfortably though life. Without working on your balance and stability your weightlifting and strength will be limited and less efficient. Though we may imagine weightlifting as just putting weights on a bar and lifting it. The truth is that knowing how to move will increase our abilities to gain strength and muscle much more effectively.
