high vs. low impact, or combo?

[junglist]

im going to attempt training both high and low impact resistance/cardio.

im thinking of training in two-week splits. week one: heavy/slow rep schemes, long breaks, light cardio
week two: light/quick rep schemes, short breaks, intense cardio.

im thinking this may speed up my metabolism and aid in getting leaner and harder. give me some size but speed, strength and endurance as well.

im still stretching before/after workouts, find I dont get sore anymore but my muscles are no doubt exhausted. I did chest tues, felt absolutely nothing sore on thurs and went to do shoulders. I could even lft the weights! I didnt have any tell-tale signs of exhaustion prior to the workout but damn i worked them hard..

anyone care to comment on low-high impact splits? would it be better to do it every other workout?

if you are a bb'er looking to keep mass, go low intensity-if not, you can go high intensity

I like the idea but I am unsure of how the intense cardio will affect your LBM. I'm cutting up right now and basically all that I have done to change my routine is to wait around 40-60 seconds in between my sets instead of my usual 120 seconds. Do you warmup before your stretching at the beginning of your workout?
