A visit to any gym at a peak time
and you’ll see it all. Some might be lifting heavy while others might be
working with lighter weights. Then you’ll get the members who spend hours on
the cardio machines leaving a trail of sweat behind them and then you get the
ones who train in a sweat jacket like they’re trying to make weight for an
event. The interesting part is that often they all have the same goals which are
to build muscle and lose fat.
In this article I’ll be looking at how
to train for gaining muscle and what different types of training routines are
commonly used by gym members and I’ll try to include examples of when I’ve used
them myself.
Types of Muscles
Some of the boring stuff first.
Muscles in the body can be split into three main categories which are smooth,
cardiac and skeletal muscle.
Smooth muscles are found in organs of the body
where movement is necessary to perform their task. For example the stomach
needs to churn food and the intestines need to move this along further down the
digestive tract which is done by smooth muscles found in these organs. Smooth
muscles are not consciously controlled. Cardiac muscle is found in the heart
and also contracts involuntarily. Finally skeletal muscle is controlled consciously
and is what enables us to move around. This is the muscle we are concerned with
building and making bigger, (not to neglect the importance of having a big
heart).
Skeletal Muscle Hypertrophy
Skeletal muscle can be trained and
as a result of this training it will adapt. These adaptations can vary but
we’re interested in making it grow. This adaptation is called hypertrophy. For
a muscle to grow it must be subject to a certain stress which we apply by
forcing the muscle to perform a movement against resistance. When the muscle is
continuously subject to this stress it begins to adapt. When this stress is
removed the muscle will tend to revert back to a smaller size as it doesn’t see
the need to remain big and maintain this adaptation. This is seen in astronauts who spend a long time in
space. As there is no gravity in space
the resistance on an astronaut’s body is removed and the muscles in the body
have no resistance to work against. They lose muscle size very quickly and
regain this muscle size when they reintroduce the stress on their muscles
caused by gravity on Earth.

So to get a muscle to continuously
grow we need to keep training it and furthermore we have to keep increasing the
stress we subject the muscle to. This is known as progressive overload.
Progressive Overload
Using the astronaut example we can
see that when they are back on Earth they go back to their original size but
they won’t continue to grow past this. This demonstrates the importance of
progressively overloading the muscle for it to adapt beyond its current size.
If the gravitational pull of the Earth became stronger overnight we would all
become swole in a few months just by keeping posture against this increased
force.
Now there are a number of ways with
which we can overload the muscles and apply stress to stimulate growth
including increasing weight, increasing reps and sets and increasing how
frequently the muscle is trained.
Thinking back to all the different
people in the gym doing all sorts of sets and reps ranges you can see that
people tend to differ in what they believe is the best way to stimulate muscle
growth. There have been many different routines that have incorporated
different techniques to overload the muscles such as forced reps and drop sets
and many people tend to stick to certain ways to overload the muscle simply due
to preference but few look into what works best.
Most training routines will work
and cause some growth in muscle size but whether or not they are the best for
muscle growth is debatable. Two of the most popular training routines, HIT and
High Volume Training are where a lot of these techniques stem from and they
have been adapted in many ways.
HIT (High Intensity Training)
Popularised by Mike Mentzer
throughout the 80s and later adapted and reintroduced by Dorian Yates, HIT is a
style of training which many lifters swear by. This style of training focuses
on working towards a max effort set where you will perform certain number of
repetitions which usually fall in between a rep range of 6-8 reps where the aim
of the set is to take your muscles to complete failure. Complete failure is
when you cannot perform another rep without sacrificing form and this was
thought to be the ultimate stimulus for growth by HIT fans.

The sets building up to this max
effort set are often considered warm up sets and are not taken to failure. When
you are on your final set a training partner or spotter can be quite important and
can help you perform assisted reps or other techniques such as rest pause reps
can be used if training alone. Using this style of training you would usually
train each muscle once a week or once in a micro cycle (more on training cycles
in the follow up to this article).
Now the idea of HIT training was to
progressively overload the muscles by continuously adding weight to the bar.
This is where the limitations of HIT training begin as there is only a certain
amount of weight you can keep adding. Although strength does increase over
time, it tends to increase at a diminishing rate. So you notice that your strength
goes up slower and slower over time. Relying on this as the only variable to
change cannot be the best form of overload. This is probably the main drawback
of this type of training. Not to say that it doesn’t work, but it isn’t the
best way to train for hypertrophy.
From my personal experiences with
HIT I found that as a beginner I did see results and some of my biggest
increases in size and strength came from HIT training. But I put this down to
using this training early on in my lifting years at a point where any routine
would yield significant results if performed consistently. I was still training
with a HIT routine until a few years after having experimented with other various other routines but I felt that it wasn't working as
well as it had done before and I decided to move away from it and try a different
approach.
Volume Training
Although volume training is not
really a strict category as much as HIT training is, it is often used to
describe routines that have a high number of sets which are taken to a high
number of reps. These types of routines are typically the ones shown in
bodybuilding magazines where each muscle is hammered by using 4-5 exercises per
body part with 4-5 sets per exercise where you can perform up to 20 reps per
set! (hence the name volume training).
Arnie took a high volume approach
to training and a quick search of any of his routines that he used shows that
he was a big fan of performing a high number of sets per exercise.

The aim of volume training is to
work the muscle in a way where you fatigue it over the course of a workout and
often each muscle is trained once a week similar to the way you would train
using HIT. Volume training uses various techniques to induce overload such as
drop sets and super sets and a big focus of workouts is to get a pump where your
muscle is full of blood from all the sets and reps performed. Arnie was a big
fan of the pump as most of you know.
When I tried using a high volume
approach to training I can say it was probably amongst the most enjoyable
workouts to begin with but over time I found there was little structure to the
routines and I would jump on any machine and just perform 4/5 sets on that
particular exercise. One problem with this was that it was almost impossible
for me to track progress as I didn’t know if I was getting stronger at a particular
movement. I also found that volume training took a lot of time and I could be
in the gym for many hours most of which was training time and not much rest
time.
So What Works Best?
Both of these approaches to
training can get you results but I don’t believe that sticking strictly to one
method is the best way to approach your training. Having a routine which
involves a certain amount of HIT work and high volume work can work a lot
better. So this can be done by having sets where heavy weight is lifted for a
shorter number of reps and having a certain amount of reps where lighter
weights are lifted for a higher number of reps.
The HIT training methods and volume
training methods are just two categories which are often considered to be at
opposite ends of the spectrum when it comes to training variables and they
directly focus on the two primary routes to achieving hypertrophy which are
myofibrillar hypertrophy and sarcoplasmic hypertrophy.
Myofibrillar hypertrophy is when
the muscle fibres are growing larger and this is often the focus of HIT or
tension training where there is particular emphasis on causing damage to muscle
cells through time under tension and heavy resistance. Sarcoplasmic hypertrophy
is the increase in the muscles energy stores, namely glycogen. Volume training
seems to be designed to achieve sarcoplasmic hypertrophy where the high number
of sets and reps deplete these stores with the aim of achieving super
compensation after the workout once your muscle has adapted and is able to hold
more glycogen than before.
Although these are two different
routes to achieve hypertrophy most workouts will achieve an overlap and give
the trainer aspects of both types of hypertrophy.
Some may make an effort to focus on
one particular type of hypertrophy in the belief that it gives their muscles a
better look. Supporters of HIT training argue that myofibillar growth keeps
them looking denser and less puffy whereas volume training may not achieve this
type of look for their muscles. Going by this, volume training might not actually be the best
way to get a leaner look and there certainly isn’t any rationale behind
switching your whole workout to a high rep, light weight routine which is what
many people do when they’re looking to cut (people who say they’re toning aka
toners). It’s probably the worst thing you could do when you’re trying to maintain
muscle while losing fat but I’ll write a whole article on that alone, this is
training for gaining!

Finally, I want to talk a bit about
power training. Power training is where a large load is lifted for a short
number of reps creating enormous tension on muscles. This can be thought of as
an extreme at the opposite end of the training spectrum to volume training as
there is hardly any depletion of energy stores apart from creatine phosphate
and ATP. Power training is usually performed on compound movements such as
squats deadlifts and bench press with a break of over 3 minutes per set to
allow creatine stores to be replenished.
Power training, apart from creating
the largest tension on muscles also creates the biggest strength adaptations
resulting in strength gains. However, since the time under tension is not as long
as it might be while using a HIT training routine or even volume training because of the lower rep
range, power training shouldn't be used alone for achieving hypertrophy but is
a very useful addition.
I’ve found that since I’ve started
power training my strength increases have complemented my hypertrophy gains and
also I’ve found power training to be the most enjoyable type of training, apart
from when I almost broke my back. Adding weight to the bar and aiming to beat
your previous best can be a highly motivating factor and I’ve found that it
helps me make consistent progress. Adding a number of power sets to your
workout can mean you’re spending a lot more time in the gym because of the rest
needed in between sets to fully recover which is something to consider when designing your routine.
Putting it Together
Now that we’ve covered both HIT and
Volume training and understood how they can achieve myofibillar and
sarcoplasmic hypertrophy we can start to make a routine with the addition of
some power work to help some strength gains.
Where most micro cycles will train
each muscle once per week there has been a lot of research showing that this isn’t
the optimal way to train. Where one might perform 10 sets on a muscle group
they would be better of splitting that workout into 2 separate workouts both
consisting of 5 sets. This is because you get to have a better workout each
time as you aren’t going to be exhausted half way through the workout. More importantly, this allows your muscles to have twice as many periods where it has been
stimulated for growth allowing greater muscle protein synthesis amongst many
other factors which add to your gains.
When you begin training each muscle
twice a week from having trained it once a week for most of your life you might
notice that you find yourself to be very sore or still fatigued from your
previous workout but it is important to push through this as it only lasts a
short number of weeks after which you adapt to the increased frequency.
So when training each muscle twice
a week it doesn’t necessarily mean that you’ll have twice as many work outs
because you can begin to pair more muscles together since you won’t be
performing as many sets as you might have done before. Also you want to
structure your routine so that you can include some power work along with tension
work and a certain amount of high rep work so that you get the best of strength
gains as well as myofibillar and sarcoplasmic adaptations. I like to perform
most of my power work towards the start of the week and then perform the
lighter work towards the end of the week as I find this to be the best way for
me to lift the heaviest weights in the power workouts.
The routine that I’ve stuck to for
the longest since incorporating these techniques has been an upper/lower split
where I train both upper body and lower body twice a week. I focus on power
workouts for the first two workouts and the second set of workouts would focus
on a higher rep range and more tension and high rep work. This can be further
broken down into smaller workouts if you find that some workouts are becoming
too long but this depends largely on how much time you have to go to the gym.
Also an important factor when
training is to keep a track of what you’re lifting in the form of a training
log. This is critical to progress because it helps you understand your
improvements in strength and allows you to better achieve progressive overload.
Furthermore, I also like to keep a
track of rest time in between sets and typically like to keep them within the
same range throughout my workouts. This eliminates any changes in strength being down
to a longer rest and I get a better understanding of my strength gains. Rest periods
are usually a between 1 minute – 90 seconds for high rep ranges and 90 seconds –
2 minutes for any tension work that falls into the 8-12 rep range. With power
work I’ll take as long as I feel I need but I still keep a record of how long
was taken which is usually anywhere between 3-6 minutes.
I’ll leave here for now and look
more into routines in the following article and look at exercise selection. I’ll
also start look at periodization and different ways to keep the gains coming while
breaking through plateaus. I’ll also be explaining how training hard and training
smart are two very different things and it’s not always best to take yourself
to failure each time especially if it’s going to be at the expense of sacrificing
total training volume which is the ultimate growth stimulator over time.
