Answer

Building leg muscle is something in today's society that isn't thought of as much as upper body strength that most people crave, and this is what the majority of the population start to think. However it is just as important as any other body muscle.

Exercise for our legs? Running. Its continuous movement of legs, requiring muscular endurance around the calves, quadriceps and thigh muscles. Continuous use of the legs in strength training will force the body to first:

• Loose the fat around these areas mentioned. Then shortly afterwards...
• Build muscle in these areas.

There's also cycling. Continuous leg movement which targets the upper leg rather than the calves, however can be still beneficial. Setting the bike on a high gear forces the thighs and quadriceps to work harder, although the calves will not receive as much of a workout.

Squats are good, using the proper technique will help build leg muscle quickly. However its important to make sure you can comfortably do a good amount of squats with the weight you've set yourself. If you can only do five or so, you're at risk of damaging your muscles and back. If you can do heaps without stopping, you're not working out and should probably select something heavier.

Of all these activities though I would choose running. It develops leg muscle very prominently if done persistently and can bring other vital fitness benefits including increased cardiovascular performance.
