Bodybuilding Defined: AMRAP, Intermittent Fasting & The Stomach Vacuum

bodybuilding defined

We all know that feeling of sitting in on a meeting as everything said flies over your head – you know it’s English but none of the terms make sense and no one wants to be stopping every sentence to ask for an explanation.

Now, think about turning up at the gym, full of pre-workout, as your bro decides today is centred on the progressive overload stage of his periodization programme where he is focusing on compound movements but will be stopping each set just short of failure. First, you are probably going to need a new gym buddy but, before you start looking, here are the definitions you need to keep your knowledge growing alongside those muscles.


You might recognise this term from some training plans – something like 70% 1RM AMRAP – so what does it mean? AMRAP is short for ‘As Many Reps As Possible’ and calls for you to discard the usual 6-12 rep range and go until failure. AMRAP sets can be particularly effective at the end of a workout or body part split as a ‘burnout’ but should generally be saved for isolation exercises or when you have a spotter available.

Intermittent Fasting

Not so much a diet as a way to structure your day of eating, Intermittent Fasting involves setting a window of time each day during which you will consume your full calorie allocation. For example, you might choose to eat from 12pm to 8pm each day (not continuously – don’t get carried away!), leaving the remaining 16 hours each day as a period of fasting. The benefits of this include the increase of human growth hormone, lower insulin levels and an increased metabolic rate.

The Stomach Vacuum

Look at any series of pictures from the classic-era of bodybuilding and you will quickly come across freakishly contracted mid-sections; something that has almost died out in the current climate of distended guts and mass monsters. Utilised as both a pose and an exercise, the stomach vacuum involves the isometric contraction of the abdominal muscles – basically, empty the air out of your lungs and pull your belly button to your spine. If you are utilising this as an exercise – and it can be an effective abs movement – hold for time and perform for reps.

Eat Big to Get Big? 10 Meals a Day??

eat big to get bigUnfortunately, I’m not one of the lucky ones who struggle to put on weight and I’m definitely not someone who has trouble eating enough food, that’s for sure. Having said that, I also don’t want to be anywhere near 100g of chicken with 50g of rice 5 or 6 times a day.

So, do you need to eat big to get big? We know that eating in a caloric surplus is required to gain muscle but does that mean eating up to 10 meals a day, Rich Piana style??

A recent Japanese study measured muscle retention in fighters cutting weight over a six week period, finding those who ate 6 meals per day were left with greater gains than those on 3 meals. However, the subjects were on a fairly crazy 1,200 calories per day and other studies were completed using subjects on low protein diets.

So, given that there isn’t much we can draw from that, lets look at some other myths that need to be debunked around frequent eating…

  • eating more frequently DOESN’T increase your metabolism
  • eating more frequently DOESN’T increase protein synthesis
  • your body CAN easily deal with more than 30g of protein per meal

But what about the thermic effect of food (the energy your body expends to process your meals)? Won’t you lose the impact of this if you eat less meals? Nope. The thermic effect has been shown to average at roughly 10% of your overall caloric intake meaning it doesn’t really matter how you break that down over the course of the day!

So, the number of meals you eat per day is another one that should come down to personal preference. As long as you are hitting your calorie / macronutrient goals, research doesn’t really support the benefits of eating up to 10 meals per day. As is always the message – find a routine that works for you and that you can maintain over time.

Personally, I find it easier to eat 3 large meals as it helps me feel fuller, more satisfied and is easy to plan around work / time in the gym.

Are you lucky enough to eat and eat without gaining weight? How do you structure your meals throughout the day??

Supplement Wars: January 2018

I’m always on the lookout for that magic supplement that is going to supersede sub-par genetics and dietary misdemeanours. I know I’m never gonna find it but the search is fun and measuring the impact of new additions to my supplement stack lets me continually monitor and improve performance and nutrition.

Supplement Wars is a monthly round-up of new additions that I’m enjoying at the moment and what isn’t cut out for a permanent space on the shelf!


I was after a caffeine free pre-workout that would allow me to continue my indulgence in the black stuff (read more about the impact of caffeine here). This is the first PHD product I’ve tried and consists of a mix of protein, arginine, norvaline and much more.

I add around 8g of citrulline malate to this to form my pre-workout drink and consume 30 minutes before hitting the gym. Admittedly, it doesn’t offer the focus or energy boost that you expect from a caffeine-based supplement but you do get an excellent pump which generally sustains through the whole workout.

At around £15 for 20 servings, it is decent value for money and the raspberry lemonade flavour is a winner.


I’m a big fan of protein bars but will be the first to admit that the quality, taste and micronutrients content varies wildly across brands.

Avoiding the chalky, heavy nightmare of some ‘snacks’, the Cyclone bar in Chocolate Caramel flavour tastes (mostly) like a normal chocolate bar. Packing 20.3g of protein and an additional 3g of creatine helps push me towards my daily goals – the bars are filling enough to plug the gaps between meals and super convenient when out and about.

Coming in at 213 calories with 8.5g of sugar puts it around average in its class but, as with most protein bars, keep an eye on that sugar content to make sure it doesn’t push you over your daily target.

Have you tried any new supplements this month? What is your go to pre-workout??
