emoticon Hi, QBASSIST.

It all depends on your *MAIN* goal.

*For me*
I want to GAIN muscle!

*For others*
They want to be ferme/fit/fat free and cut!

Once the cardio is done, the quality of our LIFTING will most likely suffer.

(( Our energy sources may be used up ))

Since we reap the most benefit from the last two or three reps of weight lifting...

It's essential that you have the necessary energy to achieve those reps.

(( So, I wouldn't do 3 X 10 minutes of cardio in between my sets, during my session ))

That fuel ( energy ) may not be available if you do a hard cardio workout prior or in between your sets, to your weight training program.

Consistently training in a WEAKENED state, actually lead to decrease in strength over time because it discourages your muscles from being adequately challenged.

*Cardio burns fat and carbs*

If you do your cardio first or during weight training...

The carbs may not be there to fuel your weight training session.

So, if you want to BUILD/GAIN muscle...

You should do weight training first.

Also, another reason some people believe in ---–


When it is stopped abruptly...Blood tends to accumulate in the lower body.

With reduced blood return, cardiac output decreases and lightheadedness may occur.

Because muscle movement helps to get the blood back to the heart, it is good to continue some muscle activity.

Easy cycling, walking, or any other cardiovascular exercise at low intensity will be recommended as cool-down activity...

After weight training. emoticon

Take care, emoticon emoticon

This is excellent info! I have a question regarding a scenario that isn't brought up.

I've read about mixing cardio into your resistance session to promote higher EPOC. For example, doing 10 minute cardio sessions spread throughout your resistance training.

Using a simple lower body + core resistance day as an example:

dynamic stretching
10 minute elliptical warm up
squat sets
leg press sets
10 minute heavy bag
leg curl sets
Romanian dead-lift sets
10 minute speed bag
standing calf raise sets
reverse crunches
10 minute stationary bike cool down
isometric stretching

Assuming nutritional requirements are met, what are your thoughts on this type of routine?

Though the gym I belong to is very limited in it's cardio resources (3 stationary bikes, several bags and 1 treadmill), I'm trying to incorporate this into my routine. I also plan to start stretching at home and then riding my bike or jogging to the gym (2 miles away) on non-leg days for my warm up and cool down. I will also incorporate a speed rope on non-leg days.

Thanks again for this epic article of a post!

Following these two simple instructions will guarantee success:

1. Take a baby step forward.
2. Repeat step 1.

(( Cardio...Before or after weights ? ))

This is a frequently asked question and one over which a wide spectrum of opinion exists even though it may seem like trivia if you're new to weight training.

Yet, as with many issues in the exercise sciences, answers to complex questions can be blurred by qualifications and exceptions and tempered by the exercise goals you have set -- weight loss, muscle, strength, sporting prowess, appearance and so on.

The following attempts to clarify the issue and provide some clear direction.

(( Cardio and Aerobics ))

Aerobic exercise, often called ‘cardio’ for short, is any exercise at an intensity at which oxygen can be sustainably supplied to large muscle groups over time and which places consistent demands on the heart and lung system, the cardiorespiratory system.

Cardio is something you do at a sustained pace over a longer period of time rather than in short bursts of energy such as in interval running or lifting weights.

Cardio is walking, jogging, distance running, swimming and cycling; and using treadmill, stepper, cross trainer and rowing machines in the gym.

Blood glucose and stored glucose and fats are the main fuels used in aerobics.

(( Training with Weights ))

In contrast, lifting weights is an activity practiced in short bursts of anaerobic (without oxygen) activity.

In effect, ‘anaerobic’ doesn’t mean that we stop using oxygen, it just means that the activity is of such an intensity that the muscle's requirement for oxygen is exceeded, resulting in metabolic products such as lactate and an eventual inability to continue at that intensity.

Stored muscle glucose and phosphocreatine are the main fuels used in strength training.

Now that you're clear on the essential difference between aerobics and weight training, let’s consider this in the context of doing cardio before or after a weights session.

I’ll assume that a ‘session’ is one visit to a gym for the purposes of a workout.

Let’s examine the scenarios I propose...

***Scenario 1 - Cardio after Weights***

You walk into the gym and do a warmup on the treadmill for 10 minutes, but you don't want to do too much cardio because you reckon you need the energy to max out your weights session.

Anyway, you heard that you'll burn more fat if you do it after the weights.

Saves energy for weight lifting. emoticon

This may seem to be good logic; however, doing 40 minutes of cardio at moderate pace is not going to deplete enough energy to prevent you from lifting well.

As long as you've replaced your carbohydrate glucose stores after any previous exercise session with proper eating, the body will have stored up to 500 grams, or a pound of glycogen.

A jogging or running treadmill session of 40 minutes may use about 600 calories of energy, depending on your size and pace.

Of this, some fuel will be fat, some will be stored glucose and some blood glucose.

A reasonable estimate is that you would use around 80 to 100 grams...
(3 or 4 ounces) of stored glucose out of, say, 400 grams that you have available.

You can see that you have plenty left in reserve for strength training.

What's more, if you replace some of this used fuel with a sports drink or energy bar before you start the weights, you’ll only be a little depleted from when you walked in the door.

(( Burn more fat ))

Now this one really sounds attractive, the idea being that if you deplete some carbohydrate stores, particularly blood glucose, with an initial weights session, you'll be in fat burning mode.

Theoretically this makes some sense but the fat burning zone is a mythical construct and what really matters is how much energy you expend overall.

Score for Scenario 1: sounds good, but in reality only 2 points out of 5.

***Scenario 2 - Cardio before Weights***

You get stuck into the cardio first up for 40 minutes because you think you will be too tired to tackle it at the end of the weights program.

You understand you will expend more energy with cardio when you're fresh, so you can use more energy overall in the session, which is what you're aiming for.

(( Fresh legs for better cardio ))

If you do your cardio before you lift, there’s little doubt you will do this part of your program more efficiently, which probably means at higher intensity and with a higher aerobic fitness outcome.

Heavy legs and arms after weights are not conducive to a good cardio session. I’ve tried both sequences many times, and running first is my preference even without the technical considerations.

As explained, cardio of moderate output expends considerably more energy than an equal session of weights, so if you want to maximize energy output for weight loss and aerobic fitness, doing a solid cardio session is essential.

Doing cardio first will maximize your output.

On the other hand, with attention to fueling, refueling and fluid intake, you will still be capable of a strong weights session after your aerobic session.

(( Strong arteries ))

It's also important to know that aerobic exercise is important even for specialist weight lifters and bodybuilders from a health perspective.

Cardio helps keep the arteries elastic, which is beneficial for cardiovascular health.

This is called ‘arterial compliance’ and several studies have shown that this worsens in weight trainers who do little aerobic exercise.

(( Study Shows Cardio before Weights is Beneficial ))

A study from the Human Performance Research Center, Brigham Young University, Provo, Utah, examined what happened to ten men who did resistance only, run only, resistance-run, and run-resistance sessions.

(‘Resistance-run’ means weights before cardio and vice versa.)

Here’s what they reported:

1. EPOC, the measure of the afterburn or energy output after you stop exercising was greatest when cardio was done before weight training.
2. Running after a weights session was physiologically more difficult than doing it before lifting weights.
(This has implications for efficiency and possibly safety.)
3. The researchers recommend “performing aerobic exercise before resistance exercise when combining them into one exercise session”.

This was not a large study, so the results should be interpreted with caution.

Nevertheless, this is in line with my own experience with this training sequence, and also that of some members at the gym.

Other research found that 'running economy' is also impaired after a weights session, another reason why the weights-cardio sequence is less efficient.

Score for Scenario 2: the evidence is not quite in yet, but I’ll score it 4 out of 5 for doing cardio before a weights session.

(( Cardio Killed My Muscle ? ))

Some weight trainers are reluctant to do much cardio training because they believe it produces catabolic hormones like cortisol that break down muscle stores for fuel thus interfering with the anabolic muscle building process.

Although this subject is worthy of a more complete article on weight training nutrition and metabolism, a brief response is that you can protect muscle from this process by ensuring adequate nutrition before, during and after a session and by keeping aerobic training to under one hour if you have muscle building goals.

Forty or so minutes of cardio within an adequate nutritional environment is not going to hurt your muscle.

In fact, in view of the discussion above, doing cardio after weights could be more damaging to muscle as 'beaten up' muscle strives to deal with the burden of aerobic activity.

Your immediate post-weights activity should be dedicated to maximizing the anabolic environment.

This is time for building up not breaking down.

You achieve this by eating sensibly and adequately and by resting and sleeping -- and by not doing cardio after weights.

(( Summing Up ))

Here are my recommendations:

1. Do most of your aerobic exercise before your weights program if you do both in the same session.
2. Complete your weights session, cool down then immediately concentrate on recovery, repair and rebuilding rather than additional exercise.
3. Consider separate sessions for cardio and weights on different days. This is a popular option when weight loss is not the primary goal.
You could also experiment with separate sessions on the same day, but you need to get your refueling right with this approach.
4. If weight loss is a primary goal, doing both on the same day with cardio first may offer some advantages in increased metabolism and energy expenditure.
5. If strength, rather than hypertrophy (bigger muscles) is a goal...
You probably should do cardio and weights on separate days because the heavier lifts may not go as well after doing cardio first.
You need to be as fresh as possible for those 4RMs.
6. You could mix and match upper and lower body workouts.
For example, treadmill running and upper body weights one day and lower body weights and swimming another day.
7. Don't get too hung up on this whole idea; if it suits you to reverse the order occasionally, it won't be a problem.

Take care, ~*Latisha*~ emoticon
