    The Reflexes That Help Us Learn to Move | TLR, ATNR & STNR

    n this episode of the Aligned Posture Podcast, I continue exploring human development by looking at three primitive reflexes: the Tonic Labyrinthine Reflex (TLR), Asymmetrical Tonic Neck Reflex (ATNR), and Symmetrical Tonic Neck Reflex (STNR). Rather than getting lost in complicated terminology, I break these reflexes down from a movement perspective and explore how they contribute to our early development. We look at how a baby gradually learns to interact with gravity, control the head, differentiate between the left and right sides of the body, coordinate the upper and lower body, reach, rotate, crawl and eventually become upright and walk. I also discuss what happens to these reflexes as the nervous system matures and why we should be careful about automatically blaming adult posture or movement problems on a “retained primitive reflex.” The bigger question is: how did the movement we developed early in life help shape the way we move today? A light and practical introduction to TLR, ATNR and STNR — and another piece of the fascinating puzzle that is human movement. 🌐 alignedposture.com 📸 Instagram: @AlignedPosture

    Human Evolution & Movement: Understanding the PRDSMS and PRDPs | PRI

    In this episode of the Aligned Posture Podcast, I explore some of the key concepts from the Postural Restoration Institute’s Human Evolution course, including the Postural Restoration Developmental Sensory Motor Sequence (PRDSMS) and the Postural Restoration Developmental Processes (PRDPs). I discuss how our movement develops from our earliest interactions with the ground and gravity, through reaching, shifting, crawling and eventually becoming upright and walking. We also look at how movement development involves much more than just muscles and joints. Our sensory systems, vision, hearing, breathing, communication and previous movement experiences all contribute to how we learn to organise and move our body. I also share some of my own thoughts on how these concepts can help us better understand adult movement, compensation and why I believe it’s important to assess the whole person rather than simply focusing on where someone feels tight or uncomfortable. 🎧 Aligned Posture 🌐 alignedposture.com 📸 Instagram: @AlignedPosture

    Who I Am, Why I Started Aligned Posture & My Journey With Movement

    In this more personal episode of the Aligned Posture Podcast, I step away from the usual anatomy and biomechanics lessons to share a little more about who I am, where my passion for movement came from, and why I created Aligned Posture. My interest in biomechanics didn’t begin in a classroom. It came from years of dealing with my own pain, recurring injuries and movement restrictions, and wanting to understand why these problems kept happening rather than simply managing the symptoms. I talk about my journey through studying gym instruction, biomechanics and Postural Restoration Institute (PRI) concepts, and how this has changed the way I look at posture, breathing, joint movement and the body as a whole. I also share what I’m working towards with Aligned Posture: helping people understand their bodies, improve their movement and build happy, healthy bodies that allow them to keep doing the things they love. Whether that’s lifting weights, running, improving performance, or simply moving through everyday life with more confidence and freedom. This episode is less about teaching a specific topic and more about introducing the person behind Aligned Posture — my experiences, what I’m learning, what drives me, and where I want to take this journey. 🎧 If you’re interested in movement, joint health, biomechanics or simply looking after your body for the long term, I’d love you to come along for the journey.

    Understanding the Muscles That Move Us

    Have you ever wondered why muscles have names like rectus abdominis, transversus abdominis or latissimus dorsi — and what those names can actually tell us about how the body is built? In this episode of the Aligned Posture Podcast, I break down muscle anatomy in a practical, easy-to-follow way. We start by exploring how position, direction and fascicle arrangement can help us understand muscle terminology, before working through some of the major muscles of the upper body and trunk. We cover the deltoids, biceps, triceps, lats, trapezius, rectus abdominis, internal and external obliques, TVA, diaphragm, intercostals, pectoralis major and erector spinae — looking at where they are, where they attach and the movements they help produce. Most importantly, we begin connecting individual muscle anatomy to the bigger picture: how muscles, joints, breathing and movement work together as an interconnected system. 🎙️ Whether you’re studying anatomy, training in the gym, or simply interested in understanding how your body moves, this episode will help turn muscle names into something you can actually visualise and apply.

    Range of Motion and My Approach

    Range of Motion: Assess, Apply & Reassess In this episode of the AlignedPosture Podcast, I explore range of motion and why measuring joint movement can be such a useful part of understanding how the body moves. I cover some of the key movements of the shoulder, elbow, hip, knee and ankle, including flexion, extension, rotation, abduction, adduction, plantarflexion and dorsiflexion. I also explain how I approach range-of-motion testing at AlignedPosture using a simple process: Assess → Apply → Reassess Rather than simply identifying a restriction, I look to establish a baseline, apply an appropriate movement or repositioning drill, and then reassess to see whether the range of motion has changed. The goal isn’t simply to chase textbook numbers, but to better understand how the individual moves, where limitations or asymmetries may exist, and whether an intervention creates a measurable change. 🌐 alignedposture.com 📱 Instagram: @AlignedPosture

    The 3 Planes of Movemet

    In this episode of the AlignedPosture Podcast, I break down the three planes of movement — sagittal, frontal and transverse — and explain them in a simple, practical way. We look at how flexion and extension relate to the sagittal plane, abduction and adduction to the frontal plane, and rotation to the transverse plane, using familiar exercises such as squats, lateral raises, lunges, Russian twists and chest flys. I also introduce a simple “Forward, Side, Twist” method to help you quickly identify each plane, along with the “Joint, Action, Plane” approach for analysing exercises. Whether you’re studying anatomy, working towards a personal training qualification, or simply want to better understand human movement, this episode will help make the three planes easier to recognise and apply.

    Muscle Movements

    In this episode of the AlignedPosture Podcast, we break down the main muscle groups of the body and the joint actions they help produce. We explore key movements including flexion, extension, abduction, adduction, rotation, plantarflexion and dorsiflexion, while connecting each action to muscles such as the pectorals, lats, deltoids, biceps, triceps, abdominals, glutes, quadriceps, hamstrings and calves. The aim is to make muscle anatomy easier to understand by connecting anatomical terminology with movements you can actually see and perform. Whether you’re studying to become a personal trainer or simply want to better understand how the body moves, this episode provides a straightforward introduction to muscles and their joint actions.

    Type I slow-twitch, Type IIa fast-twitch and Type IIb fast-twitch fibres

    In this episode of the AlignedPosture Podcast, I break down the three main types of skeletal muscle fibres: Type I slow-twitch, Type IIa fast-twitch and Type IIb fast-twitch fibres. We look at how each fibre type differs in terms of contraction speed, force production, fatigue resistance and the types of exercise they are best suited for. I also explain how muscle fibre recruitment changes as exercise intensity increases, and why understanding fibre types can help with training for endurance, strength, speed and power. This episode keeps the science simple and practical, giving you an easy way to understand how our muscles respond to different physical demands.
