Most everyone gets depressed from time to time, and many cases do not need drugs, counseling, or hospitalization. What we eat and drink, and how much activity we have in our lives, can directly affect our mood. When we load our bodies up on sodas, fried fast foods, potato chips, and desserts, our moods changes. At first, we may feel more energetic. But once the sugar or carb high wears off - here come the blues.

Some cases of depression are more serious, and do require a doctor's intervention. When someone is suicidal or hearing voices, they need immediate medical care. But for the cases where it's a feeling of blahs and a lack of energy, putting on a pair of tennis shoes and doing some exercise can help turn it around.

Exercise creates endorphins, which are the body's "feel good" chemicals. People pursue this through through many personal activities. But taking a simple walk or doing a little bit of dancing can give your body and mind that natural high it needs - and unlike the one created by sugars and starches, you won't crash back down into depression afterwards.

Even seriously depressed people, once they are out of medical danger, are likely going to be told by their doctors and therapists to walk or do some form of exercise every day. They are going to feel better when they don't eat junk food.

Weight gain is also depressing in itself. Making small changes, like even one walk a week or dropping a few sodas a week, can and do add up over time. Then you can fit into those exercise pants you always wanted but felt you might never get to wear. Walking up the block requires minimal time investment, and no money.

Exercise is nature's antidepressant. Even if you aren't depressed, it can stop you from getting that way. There really are more benefits to fitness and good eating than a healthy, fit physical body. When striving for success in your fitness and diet regimen, don't forget you also need to take care of your mind.

Some people dread the word lunges when it comes to exercise, but lunges are one of the best exercises to work your lower body. They can help tighten and tone your calves, hamstrings (back of your legs), quadriceps (thighs) and also slim down your hips and stomach, while lifting your butt. That is a lot for a simple exercise. Add in some arms raises or biceps curls with weights and you can get in a total body workout. Best of all, there are different variations of lunges that work to specifically target a certain muscle in your lower body.

Here is how to do the basic lunge:

1. Stand with your feet approximately hip-width apart with your hands on your hips or down by your sides holding dumbbells.

2. Take one big step forward with one of your legs.

3. Bend the knee of your front leg until your thigh is parallel with the ground as you also bend the back leg so that the knee comes down towards the ground. The back leg should be balanced on your toes.

4. Raise yourself back up and step your front leg back to the starting position.

5. Do your set on your one leg and then switch your lead leg to work both legs evenly.

As mentioned, there are quite a few varieties of lunges that you can do. With a static lunge you don't take your step forward, but just drop your back knee down into a lunge position. Side lunges are a little bit different movement as you are taking a step out to the side and lunging that way instead of stepping forward. A side lunge works more of your inner and outer thigh as well as your hips.

You can also add other fitness equipment into your lunge workout. Add resistance bands under your feet to make your legs work harder. Or place your back foot up on a step to switch the focus of the exercise almost entirely on the front leg and thigh.

Be sure that you have a good pair of tennis shoes on when doing lunges so you do not injure yourself.

Lunges are a great exercise to add to your exercise routine. They also make a great addition to any circuit training routine as well. If you want toned and tighter legs and butt, then you need to start practicing your lunges.
