Lifting weights is a great way to work out, increase your personal energy level, and develop good muscle tone, as well as a way to bulk up. For many guys bulking up is the primary goal of losing weight and girls have for a long time resisted the idea of lifting weights for fear of bulking up. Fear no more ladies, by building muscle tone you are eliminating fat and burning those pesky calories.
In addition to those goodies is the energy boost that lifting weights provides. If you lift weights early in the day you will have an initial boost of energy, if you find that you are sluggish near the middle of the day, try lifting weights then. I believe you will find that lifting weights will provide just the spurt of energy you will need in order to make it through the remainder of your day. Others find that lifting weights late in the day is relaxing and prepares them for a good nights rest.
In today's world where obesity is becoming more prevalent in young and old alike, developing a habit of lifting weights on a daily basis is a great way to tone your body and help your body passively burn calories. If you haven't considered this as part of your daily fitness regimen, then perhaps it is time you do.
