Weight Training - Pulsing Lunges

The final segment of this weight training circuit is my favorite.  Do it long enough and you get a great burn.  To round out this series of weight training, what better model to show you what's what than a bad-ass chick.

This girl is not afraid to get in your face and make you train right.

For this exercise you want to start down in the lunge position.  Rest your weights on your shoulders.  Your back leg is going to be extended fully, toe planted on the ground.  Your bent knee should be at a 90 degree angle, your thigh perpendicular to the floor.
Keeping your back leg straight the entire time and both feet planted throughout, straighten your front leg, and then return back into a lunge.  Repeat 10-15 times and then switch legs and do another 10-15 reps.

I like to do five full circuits, so when all is said and done, each leg has pulsed 75 times.  It's the deep burn.
