5 Most Effective Leg Building Exercises
 

Squats. The king of all muscle building lifts. 'Nuff said.
Front Squats. Another top choice of bodybuilding beef kings. Front squats can be tricky to learn, but you will be rewarded with big wheels.
Stiff Leg Deadlifts. Beef up your hamstrings!
Leg Press. If you don't have access to a squat rack this is your next best bet.
Barbell Lunge. Lunges are another quality leg-building staple.

You think lunges are better than hacks :p what craziness is this.

I love front squats :P
