i Love what you call "walking lunges" I've always called them Lunge Steps. They are the Killer. I've started with 2/25 walking the lenght of the basketball gym. They are way easy to over do.'
I have worked up to 2/150... Now that will get you ready for anything!!
The advantages to doing a moving lunge over a stationery one are many. You are using you body weight for resistance, and typically doing more so that you are building muscle endurance and strength. It develops the body's proprioceptive sense... balance and awareness of where you are in space, which is excellent for all sports. Plus it works the core a little more.
