SESSION NOTES: Heavy Barbell Conditioning (420)

This session contains one element of each of the four major barbell movement types, through a combination of powerlifting and Olympic weightlifting. Movement types include anterior chain (or squat-based), posterior chain (or deadlift/hip hinge), upper body press and upper body pull.

The inclusion of all movement types ensures musculo-skeletal balance, and also creates a ‘blood shunting’ effect, where your body is required to deliver oxygen and fuel, and remove waste, from large and alternating muscle beds.

This session isn’t the most effective method of getting strong, nor is it the best way to build cardiorespiratory endurance, however, it is highly effective at achieving a mix of both in one session as a form of concurrent training. Percentages are programmed rather than weights to ensure the correct stimulus, that both cardiorespiratory endurance and muscle strength are trained equally.

It trains your ability to move heavy weights under cardiorespiratory duress.

The requirement of the reps of the complex to be unbroken means that time under tension is maximised, removing the ability to strategise to make the session easier.

This session delivers benefits from both resistance-based training, and cardiorespiratory training.

Resistance training (using your muscles to lift heavy weights, either external weights or yourself) makes you stronger. Strength is one of the greatest predictors of both your lifespan (how long you live) and your healthspan (how long you live in a healthy state).

Resistance training like this will also improve your flexibility (by going through a full range of motion), posture and coordination. It will also build stability around your joints and spine to give you a healthy musculo-skeletal system and reduce joint and back pain.

The session will minimise losses in bone mineral density and will improve your balance. Strength and balance are the two strongest predictors of falls later in life, so this is an effective way to train fall prevention, and insure your independence into old age.

This session increases your lean muscle mass and muscle fibre size. Muscle is a metabolically active tissue, so increasing it will maximise how much energy your body burns at rest. This makes it an effective session to reach healthy levels of body fat, both visceral fat (around the organs) and subcutaneous fat (under your skin). After this session, your body will go through a prolonged state of ‘EPOC’ (excess post- exercise oxygen consumption), meaning you’ll continue burning energy long after you finish training – further aiding healthy body composition.

The cardiorespiratory element of this session also has considerable health benefits, with this session creating favourable changes to cardiovascular disease (including reductions in blood pressure) and respiratory disease. This session will also lower your resting heart rate and increase blood flow to the brain.

As a result of this style of session, you will experience changes in blood chemistry, including favourable effects on cholesterol, blood glucose, triglyceride and lipid levels.

The heavy levels of resistance in this session are designed to increase your strength – increasing both your one rep max, and your ability to lift submaximal weights. By being stronger, you can lift more weight, and you will be able to lift submaximal weights faster and for higher reps because they’ll be at a lower percentage of your max.

As strength is an element of power, getting stronger will also improve your ability to move faster – beneficial for more power-based, explosive movements (like Olympic lifting).

This session will also improve the efficiency of your fast-twitch muscle fibres (those responsible for lifting heavy and fast), and will improve your neuromuscular efficiency (your ability to turn on a very high percentage of your muscle fibres).

The primary benefit of completing resistance training under cardiorespiratory duress from a performance perspective is to improve the ability of your body to sustain repeated muscle contractions.

This session achieves this by training the glycolytic and oxidative energy systems which generate ‘ATP’ (adenosine triphosphate) which fuels movement. By completing this session and training these energy systems, we’re able to raise the lactate threshold, the intensity at which hydrogen ions begin to accumulate, causing cell acidity. Raising this threshold allows you to exercise at a higher rate for longer, with less fatigue.

As a result of this session, you’ll experience performance-boosting changes in intramuscular substrate storage (increasing energy availability for muscle contractions) and increased enzyme activities (increasing the rate of energy delivery to the muscles).

Additionally, the repetitive muscle contractions create positive changes at a muscular level.

The high repetition movements in this session train the ability of your muscles to resist fatigue – increasing their stamina. This comes from improvements in the efficiency of slow twitch (fatigue resistant) muscle fibres.

As a result of the volume of repetitions, this session will increase the mitochondrial density in your muscle cells, allowing them to more efficiently convert energy into fuel. This means you can sustain higher rates of muscle contraction before fatigue or failure.

The higher volumes will also increase capillary density in your muscles, allowing for efficient delivery of oxygen and fuel, and removal of waste products (further adding to the fatigue resistance).

These muscular changes also occur in the ventilatory muscles, particularly with the need to breath and brace while lifting heavy loads, improving breathing efficiency.

The cyclical nature of the complex improves the ability to move the barbell around the body quickly and efficiently.

​

Aim to get three sets completed in the first 10 minutes, leaving ten minutes for the remaining two sets.

Beginning at the indicated percentage, you should aim to make relatively large weight increases between sets one and two, and between sets two and three. As you progress through the five sets, the weight increases should become smaller as you get closer to reaching your max.

This session is about balancing movement speed (cycling quickly through the reps of the complex) while also ensuring you’re not working at too high a rate too early (which can cause you to hit a threshold). Don’t be afraid of pausing at certain points of the complex for a couple of breaths in the latter sets.

In the rest intervals, you should complete active recovery (keep moving), to help to ‘buffer’ hydrogen ions out of the blood and maximise your recovery for the next interval.

You should feel equally limited by your cardiorespiratory endurance and strength/stamina. It should be difficult both because the loads are heavy, and because you’re breathing hard.

In each set, your rate of perceived exertion should increase, beginning at 6/10 in the first set, and progressing to 7, 8, 8.5 and 9/10 in subsequent sets.

As this is based on a percentage of your own max, you shouldn’t need to reduce the weights. If you have a low ‘training age’ (haven’t been training for long), you may need to ‘scale up’, increasing the weights to ensure that you’re equally limited by both ‘heaviness’ and ‘breathing’.

Modify around injuries with exercises as close as possible to the stimulus of the movement you’re modifying.

A common issue we often see in this session is making too small jump in sets two and three. Set four should be very challenging, don’t wait until the final set before working at a very high rate. All sets, in particular three, four and five, should be completed at a high level of exertion.

Lying down, or resting passively in the rest intervals (though it feels good at the time) will also impact your performance in the following work interval.

Sacrificing form and technique under fatigue is a danger here. Although this may get you a higher score in the session, it will damage your technique and will blunt your long-term health and performance gains.
