RPE stands for “rate of perceived exertion”. More simply, RPE is just asking yourself how difficult was the set you just performed or, how many more reps did I have in reserve (RIR). This rating of how difficult a set was or how many reps you had left can be reflected or detailed using a 1-10 scale. 1 being almost no effort at all (I could do 9+ reps) and 10 being absolute maximal effort (I couldn’t do anymore reps or add anymore weight). Depending on the coach or how you personally get the most out of RPE, will dictate whether you opt for a more FEEL based approach on RPE or a reps in reserve based approach (neither of which are wrong, just different). An easy example to explain this would be an athlete who moves a weight, with what looks like relative ease, but then reports that it felt very hard and heavy. This athlete may be better off making their RPE judgements based off of bar speed and reps in reserve, as opposed to how difficult the set felt. This is where RPE can become a little tricky but also very individualised and custom to a particular athlete. Oftentimes, a mix of both bar speed/RIR and perceived effort is the best course of action and works very well for managing fatigue.
Below are two attached graphics that do an excellent job at illustrating the differences between these two approaches or different ways of phrasing the same RPE.
So why do we use RPE?
The most attractive thing about RPE and why it is so widely used is its built-in auto regulation. It considers how you feel on any given day and what your preparedness level might be for a particular session and matches that with your training. If you’re particularly stressed, under-slept or have any external factors affecting you negatively, RPE is an excellent tool to use to match our readiness to train with the weights we’re about to lift. On days we feel less than average, our weights might go down a little bit and on days we feel super strong, we can push the envelope and up our weights. This style of training manages fatigue brilliantly and stops athletes from digging their metaphorical fatigue hole even deeper, by continuing to add load to the bar on days they already feel tired and fatigued on.
How to implement RPE:
Now that you’ve got a better idea of what RPE actually is from a theoretical standpoint, it’s time to learn how to implement it practically into your training.
There are many ways to start implementing RPE into your own training and everyone has a different approach or method. The first thing to note is that you need to know what an RPE 10 feels like to be able to know what an RPE 9 and RPE 8 feel like too. You don’t have anything to draw from if you’ve never experienced true maximal exertion. A tool I’ve commonly used with new lifters is using machine AMRAPS to teach RPE. I will assign a set load to their main compound movements and attach an RPE rating to an accessory movement, let’s take an AMRAP set @RPE 8 on a hack squat for example. Before the set begins, I’ll ask the athlete to take a set weight on this machine to what they think is an 8 RPE or to when they think they have 2 reps left in reserve instead of asking for a number of reps. Most of the time they will stop far earlier than what an RPE 8 or 2 RIR is. Once they stop and say that the set is at RPE 8 or 2 RIR, the set will continue and I’ll ask them to perform an AMRAP to see if their prediction was accurate. Most newer trainees miss the mark by up to or more than 5 reps. This kind of tool can be very useful in teaching a new lifter what 2 reps in reserve actually feels like and gives them a lived experience to draw on what an RPE 8 actually feels like. The same approach can be used with more experienced trainees who misjudge their RPE as well. Using this approach on machines gives you a safe environment to practice high effort sets without technical breakdown and learn to feel what hard training feels like and what these 7,8 or 9 RPE sets are. Once they’ve spent some time learning with AMRAP sets like these on machines, you can start the transition to their barbell training (this can be done at the same time if you like).
In my experience, the best way to start learning RPE with the barbell is to set up a camera and film your set: Before watching the video, give the set an RPE or RIR rating directly after finishing the set based on the graphics above. Proceed to watch the video (and/or send it to your coach for their RPE estimate) and give yourself a new RPE or RIR rating based on how the set looked on camera, did the RPE match the bar speed or was your perceived exertion during the set higher or lower than what you saw on the video? With continued practice and diligence with this process, your personal connection to what an RPE 6 or RPE 8 is will become more accurate and you will slowly begin to experience and make use of the advantages RPE based training can have over a more static approach like the sole use of percentages.
Common mistakes with RPE:
RPE can be difficult to use, and the FEEL based aspect can sometimes make lifters rely too much on emotion and can cloud their judgement on how a set feels. Some common mistakes I see with those new to RPE are:
Thinking an RPE 8 -9 is a max out.
Thinking an RPE 6-7 is a warm up .
Picking loads for their sets without doing an exercise first to see how you feel.
Not understanding their personal connection with RPE (lifters who move slowly undershooting because the bar speed slowed down).
Benefits of RPE:
Gives you the opportunity to handle heavier weights or PR during training blocks (specifically on singles) when you feel really strong. Most percentage based programs won’t call for a single at above 100% of your max so you don’t usually hit PR’s when running percentages during a meet prep.
Gives autonomy to the lifter so they can feel in control of their own training.
Drawbacks of RPE:
Can be poorly used if the athlete is inexperienced or hasn’t mastered their load selection.
Some athletes enjoy/need to be told what to do re: weight selection.
Stop blaming muscles, start blaming your movements
Your scapulars have 17 muscles connected to each of them. Your pelvis is connected to over 30 muscles. Over 100 muscles are connected to your foot. Reducing your movement down to muscles can get very messy very fast. You have over 600 muscles in your body and only about 206 bones in your body. Start giving more love to the movements of your bones. It will make your life easier.
So when breaking down a human movement remember to always start proximal before moving distally (I explained this in my previous blog). So for movements involving your hips we always look at what the sacrum and spine is doing.
Is it tucking/Counternutating enough while squatting (posterior pelvic tilt)? Is it extending/ Nutating the right amount during a hinge (anterior pelvic tilt)? Is your hips and ribs stacked through the whole movement? These same principles apply to your sternum and scapula but will be talked about on a later date.
Remember….. strength IS a Skill
What is Strength?
Strength is all about force production. In the world of barbell sports it is about how much weight you can lift, squat, snatch, clean and/or press. In the physiology world it is about how well your Central Nervous System (CNS) can stimulate the most amount of large muscle fibres in the least amount of time. This means there are two major factors: your CNS (coordination) and the size of your muscles.
This is where the difference between strength building and strength expressing exercises become really important.
Let’s use my favourite lift as an example. We use Low Bar Squats to express our strength but High Bar, SSB and Front Squats to build it. The reason why is because the more upright your squat is the more force is going through your legs and less through the muscles around your spine. Your legs (quads and glutes) have a much larger capacity of growth compared to your erectors.
This is where the fun part comes in: training. Just like every other skill that you do practice indeed makes perfect and the cool thing is that this practice, especially when done right will also help grow these important muscle fibres. So if you want to get better at squatting, yes you do want your quads to get bigger but only doing leg extensions isn’t the best way to get there, doing more squats is.
By now most of you would have heard of this duo once or twice in the context of rehab and/or performance. This blog is to cut through the fluff and help you get a better understanding of what everyone (including us) keeps talking about.
Breathing is the key
Stretching ≠ improving mobility
You need to be stable to be mobile
Mobility vs flexibility – what’s the difference?
Mobility is different to flexibility. Flexibility is passive and Mobility is active. I am a perfect example of this. When someone puts me into position I have a ton of passive internal rotation of the femur, but when I try to get there myself I cramp really fast.
Remember stretching only has a short term effect. The real thing that will improve your mobility is learning how to move properly. We all know by now that we are stuck in certain patterns and postures. For example, I am super extended with a duck butt (anterior pelvic tilt). What that means is that my center of gravity is naturally tipped forward. This adds more pressure on my ankles and decreases my dorsiflexion. I can do all the ankle stretches in the world, but until I learn how to get out of my duck butt by learning how to stack I might as well hit my head against a brick wall.
Are my ankles tight or am I just shit at squatting?
The majority of the time people blame their ankles on their poor coordination. Remember squatting like every movement is a skill, just like how a musician has to practice for years to be good at their craft we too need to practice getting into positions. The most important factor for getting into these positions is being able to stay stacked and subsequently use the prime movers of the exercise.
The stability we talk about is in the context of strength-skill and force production, and less in the terms of bosu balls. The more stable you can be, the less energy is lost unnecessarily. This is where I introduce to you a new concept called ‘proximal to distal’. I mentioned it before in the ankle mobility example.
Put it simply, the more stable your spine can be, the more force you can transfer through your hands and/or feet. Or put it another way: the less stable the hip and scapular the more jacked up the ankles and forearms are. This is mitigated through a good quality rib-cage and pelvic stack.
So what is a stack?
A stack is when you are able to get into and maintain a neutral spine throughout a movement. An effective brace is only properly utilized when you have stacked your hips and ribs over one another. Take a look at the examples below, can you spot which one is incorporating a proper stack?
The most effective way that we teach people how to stack their hips and ribs is through breathing drills. Now, I know what you are thinking: “I have been breathing my whole life, why the hell do I need to be taught how to breathe”. Throwback to my previous blog, we know that we are stuck in certain positions. Breathing drills are a great tool that we use to ‘reset’ our posture. It teaches you what neutral feels like and allows you to know how to brace properly. This is explained further in our Training Fundamentals course that is available on our website.
Hopefully this will help you to do some problem solving of your own – if you have a pesky ankle or wrist, focus on getting stronger rather than stretching till the cows come home.
Most of us use exercise as a method of maintaining our mental health. If we start experiencing pain in our back when we run, squat, do push ups, pick up our kids of the canine, feline, and primate variety; we tend to not want to do those things anymore and our mental health can suffer from that.
So I’m going to paint a word picture for you:
“But Michael, I like doing group fitness because it takes my mind of things and I don’t have to think about what I’m doing”
I hear this one a lot. What I also hear a lot is….
“I don’t do squats, it hurts my knees”
Okay, so you enjoy the group-based environment but you are unable to partake in certain exercises because of knee pain? Why don’t you get someone to have a look at those knees, hips, ankles, back or whatever else could be the cause of that knee pain?
“Use it, or lose it”
“Motion is lotion”
Your body is a lot to think about. You do enough thinking during the day when trying to organise meetings, projects, kids, clients, orders. Why should you add something else to the mix and stress you out further?
Moving efficiently is all about making small wins for yourself and changing your mindset about movement-based challenges. Once we’re able to get a roll going with these small wins, the fundamentals are going to feel so much better and you’re going to experience far less stress. Couldn’t feel your hamstrings during a deadlift but now you can? You had back pain but managed to feel your glutes firing and that back pain has disappeared? That’s a success right there. It gets you pumped. It gets me pumped. These wins will echo into your daily routine, reducing the stress and anxiety of your daily grind.
My biggest challenge in the mental health field is trying to get people to care about how their body moves and have fun while doing it. If your body moves well, you’re much less likely to end up in pain. If you’re not in pain, you’re going to want to keep moving. You keep moving, you hit your health and fitness goals, your brain will thank you for it.
Strength training and moving well is not just good for your pain, it’s good for your mind.
We all grew up being told to ‘stand up straight’ and to ‘stop slouching on the chair”. Nowadays sitting has been described as the new smoking and stand up desks are selling out faster than hot cakes.
What if I told you that these beliefs are possibly causing more harm than good?
Stop labeling your posture as good or bad
Posture only matters when load is involved
You are the only person in control of your body (hopefully)
Okay before I do a deep dive into this topic, let’s define posture.
Posture is the default movement patterns and positions that your body likes going into.
Everything in nature is inherently lazy. Your body prefers to be in certain positions because it is comfortable, and that is completely normal. So labeling a posture as good or bad could be leading you into something called “guarding behaviour”.
What is guarding?
We all have seen those videos of cats overreacting when jumping onto alfoil on the kitchen bench (if you haven’t, stop what you are doing right now and look it up). From now on that cat is going to expect a rude shock whenever it jumps on the counter top – and actively avoids it. You are the same. You learn that a particular movement may cause discomfort so you actively avoid doing it. Let’s use pushing your knees over your toes as an example. The problem lies in the fact that you are not made of glass, you are not fragile and you ARE MEANT TO MOVE.
“Motion is lotion, rest is rust”
Dr. Anne Schuchat
By not moving your knees over your toes what happens is that the muscles in this case your quads atrophy (shrink) and sensitize. This means that when you go to use your knee – your muscle fatigue quickly and starts to hurt. Due to this extra sensitization, what would normally be a 3/10 pain ends up being a 10/10 pain; Unfortunately this can spiral. That is when a good health professional (like one our amazing EP’s) educates you on how to desensitize this area.
When does posture matter?
When force transfer is involved. Be it running a marathon, squatting 300kg or simple picking your kid off the floor. These are times when having a stacked neutral posture matters. If you are able to properly load the prime movers of the exercise it means that you are able to do the activity more efficiently without overloading the secondary/ supportive muscles. There are people who are naturally flexed AKA kyphotic, others who are extended AKA lordotic, and some who are both. The first step is to figure out what posture you have. A good way to know this by looking at your lifts. If you are good at squatting chances are you are probably flexed. And if you are good at deadlifting you are probably extended. After you have figured out what posture you have the next step is to learn how to stack, breath and brace. This is a whole other can of worms that needs to be opened on another day.
