The Depletion Workout – Two Hours,
Really?
The depletion
workout can be a deciding factor for many considering Body Opus. While Dan is vague about sets, reps and even
exercises, he was adamant the depletion workout would take up a lot of time in
order to be effective.
Dan writes
the goal of the depletion workout is to, “…deplete muscle glycogen, not to make
Hamlet-length monologues into the ralphing pail.” You deplete muscle glycogen to increase your
store of glucose to glycogen converting enzymes before you replenish your
glycogen stores, or “carb-up.” Carbing
up is a trick bodybuilders stole from endurance athletes. Endurance athletes did it to extend the
amount of time they could compete without “hitting the wall.” We do it in Body Opus to supercompensate
muscle glycogen levels and cause what Dan describes as, “…kinetic anabolic
expansion.”
On page 315
Dan states he was unable to, “…finish Friday’s whole body depletion workout in
less than two hours…” during my first
attempts at Body Opus, I stuck to that mindset and my depletion workouts
clocked in around two hours. Over the
three years I have been doing Body Opus, several things have changed my view
and approach to the depletion workout.
Sustainability – Since I plan to do Body Opus over
the long term, does carving a two-hour chunk out of my life every week make for
something I can do over the long term?
For me the answer is no. I needed
to deplete glycogen, but are there ways that are more efficient?
Goals – The depletion workout and the
weekend feeding schedule laid out in the book are aimed at bodybuilders
preparing for a contest. An athlete
would do Body Opus over successive weeks leading up to the contest. I am not competing, so when I come out of the
recomposition over the weekend, I’m looking at another week of Body Opus. My rationale is that I can still deplete,
still carb up without being as stringent as the plan in the book.
Workouts – Dan left the actual exercises vague
so readers could plug in exercises that worked for them. The circuit recommendation was innovative for
its time; however, myriad exercise protocols emerged since Body Opus. Of particular note are Charles Staley’s
Escalating Density Training (EDT), and Kenneth Jay’s Viking Warrior
Conditioning. More on these later.
In revamping
the depletion workout, I used Dan’s dictum of “exploring the limits of
slackness” in my approach. I asked
myself, “What exercise protocols can I use to do the most depletion in the
shortest amount of time?”
Charles
Staley’s Escalating Density Training is a system that pairs antagonistic
exercises (exercises that work opposite muscle groups, such as bench press and
row) for a 15-minute session. Charles
recommends using a weight that allows you to do 10 reps, but not 12. In the example of bench press and rows, you
would do eight reps of bench press (Exercise A1), then immediately do eight
reps of barbell (or dumbbell) rows (Exercise A2). EDT is about fatigue management, and as Dan
says on page 313, the depletion workout is a fatigue training session.
The goal of
the EDT session is to complete as many sets (A1 followed by A2) within 15 minutes.
As you get fatigued, rather than
increase your rest between sets, think about decreasing the reps per set. Charles suggests performing triples (3 reps),
doubles (2 reps) and even singles to keep cranking out the reps up to the 15-minute
mark.
EDT is a
completely self-regulating system. When
it comes to popular bodybuilding routines (“4 sets of 12,” “8 sets of 8,” “10
sets of 10,” etc.) I am always left with the question of whether I actually
accomplished anything. Another question
is “how much do I increase the weight by?”
With EDT, the
goal is to increase the volume of each workout.
Volume, for EDT purposes, is defined by rXw, where r=repetitions and
w=weight. If the total number of reps
for bench press is 100 and the weight used is 135 lbs, then the volume is
13,500. My goal for the next workout
would be to perform more repetitions and increase that volume. Since the time (15 minutes) does not change,
performing more repetitions means you are performing more work. Increased volume over successive sessions
confirms you are progressing.
Charles also
devised a novel weigh to determine not only when to increase your weight within
EDT, but by how much. When you have
increased your volume by 20%, you may increase the weight by 5% or 5 pounds,
whichever is less. Charles’ book “Muscle Logic” lays it all
out. What I like about EDT is the fact
that each session is 15 minutes, and you probably need a countdown times like
the Gymboss to get strict about that.
With the 15-minute
sessions, you could string two or three together for an intense depletion
workout. I usually work from larger
muscles (chest/back) down to smaller muscles (bicep/triceps). “Muscle Logic”
has a great section of possible A1/A2 combinations, as well as tips on getting
the most out of EDT. When I used EDT for
my depletion workout, I would perform four sessions, two upper body and two
lower body pairings. While that clocks
in at an hour of training, once you factor in rest between sessions and
equipment set up, most workouts took about 90 minutes.
When I was
pressed for time, I would pare it down to three sessions and if I did not
tarry, could knock out a depletion workout in an hour. For the shortened depletion, I would perform
two upper body sessions and one (heavy) lower body session. Instead of the depletion workout being an
unknown black whole of time on Friday, EDT imparts a level of precision on that
workout. In addition to strength
training, the continuous nature of each session, combined with the fatigue
management challenges imparts an aerobic training aspect to the session.

Kenneth Jay’s
“Viking Warrior Conditioning” takes precision to another level. Where EDT sets the length of the session at
15 minutes, Viking Warrior Conditioning gives you 15 seconds to perform a
specified number of reps, followed by 15 seconds of rest that equals one set. Rinse and repeat. Did I mention there is only ONE exercise for
this protocol? That’s right, kettlebell
snatch. The ultimate goal is to perform
80 sets, which will take you exactly 40 minutes.
With Viking
Warrior, Kenneth Jay singled out the kettlebell snatch as an exercise that
addresses not only overall strength, but when using his 15-second work/15
second rest protocol, has specific cardiovascular impact. “The Dane of Pain” as he is known, claims Viking
Warrior Conditioning will positively influence ejection fraction.
I used Viking
Warrior Conditioning for my workouts during the week, so using it for my
depletion workout was a logical progression.
I like that it is scalable. If I
only have 30 minutes to work out, I know my goal is 60 sets (at 15:15 you’ll do
two sets per minute). The snatch is a
whole-body exercise that engages the core.
Of course, Kenneth gives you the complete testing routine that shows how
many reps per set for the 15:15 protocol.
When training
for an upcoming 5k, I can fold in treadmill runs with the Viking Warrior
Conditioning by doing 10 sets of snatches using the 15:15 protocol, then
following that with 10 minutes (or one mile) on the treadmill. After four sessions of these, I am depleted.
So, that’s my
story on the depletion workout. I think I
have found an alternative to Dan’s recommended two-hour depletion workouts, but
your results may vary. I had specific reasons
for the choices I made and you’ll have to factor in your own situation in
making decisions about the depletion workout.
EDT and Viking
Warrior Conditioning are great tools to make workouts more efficient. For me, time is a factor. I don’t have the time to spend two hours in
the gym, or even working out at home. I
also like the precision of both systems, as well as the ability to see and
chart gains. If I ever get to a point
where I really want a pumped “after” picture, I probably will revert to the
two-hour depletion workout and a variation of the feeding schedule, but only
for a weekend.
Stay strong!
