Whenever I go to the gym, I notice two types of girls: girls who stick to strictly cardio, and girls who have the bravery to explore the weight room.

I think the biggest factor that stops those "cardio girls" is intimidation. We are intimidated by the men in the weight room. We are intimidated by the heavy weights. We are intimidated by the complex machines that we have no idea how to use.

That was a reality for me at one point of my life. Luckily it's been a few years, and now I'm lifting heavier than a lot of the guys in the gym.

So why, as women, do we need to venture out and explore that daunting weight room?

1. It improves bone density.

Did you know that out of the 44 million people at risk for osteoporosis, 68 percent are women? It is so important for females, especially young females, to prevent bone loss for our years to come. Weight bearing exercises stimulate bone to create density. As you age, your bone density decreases. If you take weight lifting up as a hobby now, you can slow this process!

2. It builds muscle, and muscle speeds up metabolism.

I know so many girls who say "I gain weight if I even look at a cookie." The good thing about weightlifting is, it builds muscle mass. The more muscle mass you have, the more energy you expend. AKA, the higher your metabolism is! I mean, isn't that reason enough to pick up those dumbbells?

3. It increases your endurance.

If you played sports in high school or you're a college athlete, you probably have done some form of weight training. With more developed muscle mass on your body, the better you perform in your sport. For example, if you're a runner, it's important for you to have strong calves and hip flexors. As a swimmer, strong arms and leg muscles. Catch my drift? Muscle mass will help you with any sport you participate in.

4. It will create muscle tone.

Perhaps the most obvious benefit of weightlifting is improving the look of your physique. Weightlifting will build curves, but even curves. Your body will start to look more proportional as you reduce your body fat percentage (a combination of weight training, cardio and diet).

5. It's rewarding.

If you're lifting properly and supplementing your training with proper nutrition, you can build some serious strength. There is so better feeling than being able to lift heavier than you could before. It takes hard work and dedication, but when you're serious, results come fast!

So, what are you waiting for? Get to the gym!
