1) You Live Longer. Lifting weights will increase or at least maintain your muscle mass. Research done at UCLA demonstrated a positive correlation between longevity and higher levels of muscle mass in older adults.

 
2) Stronger Bones. Strength training increases bone mass and density. This helps to reduce the incidence of fractures from slips and falls.

3) Improvements in Mood. Strength training not only can help you burn off some steam, but it also has a positive effect on hormones that make you feel better called endorphins. People that lifts weights tend to have higher levels of endorphins which have been shown to increase levels of satisfaction and happiness.

 
4) Improves Sleep. Studies have shown that people who strength train tend to sleep better at night. Part of that reason is that strength training elevates your body temperature. As the body begins the cool down process and core temperature drops, signals are sent to the brain that it’s time to shut down and go to sleep.

 
5) You Lose Weight Faster. Research shows that weight lifting tends to target certain muscle fibers (type II) in your body that burn calories at a faster rate than doing cardiovascular exercise alone. Adding two days of strength training was enough for beginners to show improvement!

6) Improves Self Confidence. Study after study shows that people who lift weights tend to have higher levels of confidence and worry less than those who do not lift weights.

 
7) Improves Flexibility and Mobility. Exercises that utilize a full range of motion have been shown to improve flexibility even better than stretching alone.

8) Helps Decrease Abdominal Fat. Fat stored around the midsection is related to an increased risk of chronic diseases that include diabetes, certain types of cancer, fatty liver disease and cardiovascular diseases. Strength training has been shown to help reduce abdominal fat, especially when combined with caloric restriction.

 
9) Helps Lower Blood Sugar Levels. Skeletal muscle helps increase insulin sensitivity. It also reduces blood sugar levels by removing glucose (blood sugar) from the blood and sending it to muscle cells. As a result, greater muscle mass can help improve blood sugar management.

10) Makes You Stronger. Gaining strength allows you to perform daily tasks much easier, such as carrying heavy groceries or running around with your kids. Furthermore, it helps improve athletic performance in sports that require speed, power, and strength.
