hey lou, i don’t actually know anyone who has used it and haven’t personally tried it, although i have heard great things about it throughout the industry.
for those of you who don’t know what it is, it is a regimen deisgned by Charles Staley, a renowned trainer/coach and writer throughout the fitness industry. EDT stands for Escalating Density Training. the general idea behind the routine is to fit in as much overall work as possible into the given amount of time, usually two grouped sessions performed under an hour total time, with a rest period in between. one thing Staley emphasizes is to simplify things as much as possible to cut down on distractions. for the most part he throws sets, reps and rest intervals out the window and relies on alternating exercises to maximize the amount of work.
it’s an intense program and people usually see huge gains on it. a lot of people will use it specifically to jack up their arms, but you can definitely make an intense full body split using this regimen. since it’s so intense i would reccomend that you take steps to ensure proper recovery.
i’d give it a try if you haven’t, especially if you are looking for some quick gains in muscle mass.
