In this article we'll be covering one of the best leg exercises which is known as the stationary box lunge.  For this exercise you'll need a sturdy box, the height of which will depend on your personal flexibility and your athleticism but just know that the higher you go off the floor the harder it'd going to be on the flexibility of your buns and your hamstrings.  If this is the first time that you'll be doing this exercise I recommend not using a box or weights but just using the flat floor or use something sturdy that is the height of an average textbook which will allow you to be one or two inches off the floor.  Once you get the feel for this exercise you can work up to using a box that is about four inches tall. 

Once you've become familiar with the motion of the lift you can add dumbbells, if you're an entry level lifter I'd recommend using fifteen to twenty pound dumbbells, if you're an intermediate to advanced lifter you can use twenty five to thirty pound dumbbells.

To get started you'll grab a set of dumbbells and put both feet on the box.  You'll stride forward putting your weight on your left leg and then lean your upper body back and push your hips and buns back like you're sitting back in a chair and lower your back knee down and lightly tap the floor and then raise yourself back up and that'll be one rep.  So this exercise will work your balance a little bit as well and get those stabilizer muscles firing.  If you're doing this lift correctly you'll feel a really good stretch in your right thigh and really feel this one working your left leg.  As you sit back and lower yourself like you're sitting in a chair with each rep the dumbbells should be landing at right about the heel of your forward foot.  With each rep it's important to focus on not letting your front knee go past your toe, if you find yourself doing that it means that you're not sitting back enough as you lower yourself.

A great finishing technique that you can use with this lift is on your last couple of reps, once your knee has tapped the ground, instead of raising it up all the way only raise it up a couple of inches and then back down and repeat that four or five times before raising yourself up all the way.  After you've done your left leg, wait about a minute to catch your breath and begin working your right leg.  By adding this workout on your leg workout days you'll be able to not only strengthen your legs but also improve your balance.
