    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.

    Skeletal Muscle Structure

    In this episode of the AlignedPosture Podcast, I break down the basic anatomical structure of skeletal muscle, starting with the smallest components — the actin and myosin myofilaments — and building all the way through to the tendon and bone. We cover how myofilaments form sarcomeres, sarcomeres form myofibrils, and how these sit within muscle fibres, fascicles and the whole muscle. I also explain the three main connective tissue layers — endomysium, perimysium and epimysium — and how they help organise the muscle before blending into the tendon. This episode is designed to give you a simple, easy-to-follow understanding of how a muscle is built without getting lost in unnecessary detail.

    Planes of movement

    In this episode of the Aligned Posture Podcast, we explore the three planes of movement covered within the OriGym Level 3 Personal Trainer course: the sagittal, frontal and transverse planes. You’ll learn how each plane divides the body, the main joint actions that take place within it, and common exercise examples such as squats, lateral lunges and rotational movements. We also look at why the body rarely moves in just one plane at a time, how multiplanar movement applies to everyday life and exercise, and why understanding these planes can help personal trainers assess movement and create more balanced programmes.

    Advanced Stretching Techniques

    n this episode of the AlignedPosture Podcast, I explore the advanced stretching techniques commonly covered within the OriGym Level 3 Personal Trainer course.   We look at active and passive static stretching, dynamic stretching, ballistic stretching and PNF techniques, including hold-relax, contract-relax and reciprocal inhibition.   I also explain when each method may be appropriate, the key safety considerations for personal trainers and why improving flexibility is not simply about forcing the body into a greater range of movement.   From an AlignedPosture perspective, we also consider how posture, joint position, breathing, stability and the nervous system can influence feelings of muscular tightness.   For more information, visit alignedposture.com or connect with me on Instagram at @AlignedPosture.

    Explaining the Left AIC, Right BC Pattern

    In this episode of the AlignedPosture Podcast, we explore the Left AIC–Right BC pattern and explain how it can influence the pelvis, ribcage, spine, shoulders and overall movement.   We break down what the pattern means, why the body may become biased towards one side, and how these imbalances can affect breathing, posture, walking and muscle tension. We also look at why tight muscles are not always simply short, and why stretching alone may not correct the underlying issue.   Finally, we discuss where to begin when addressing the pattern, including improving breathing mechanics, restoring pelvic and ribcage position, reconnecting with the left hamstring and inner thigh, and gradually rebuilding balanced movement between both sides of the body.   This episode is ideal for anyone interested in posture, biomechanics, PRI concepts and understanding how the body adapts to asymmetry.   To learn more, visit alignedposture.com.   You can also contact or reach out to me on Instagram at @AlignedPosture.

    Types of Synovial Joints and key features of them

    In this episode of the Aligned Posture Podcast, we explore the different types of synovial joints found throughout the human body and why they are so important for movement, posture, and overall joint health.   We break down the main categories of synovial joints, including hinge, ball-and-socket, pivot, saddle, condyloid, and gliding joints, and look at how each one helps the body move in different ways. This episode also outlines the key features that make up a synovial joint, including cartilage, synovial fluid, the joint capsule, ligaments, and the role these structures play in reducing friction, supporting movement, and protecting the joint.   Whether you are studying anatomy, improving your understanding of human movement, or looking to better understand how the body stays mobile and aligned, this episode gives you a clear and practical introduction to synovial joints and their role in everyday movement.

    Lift List with Safety Cues Part 1

    In this episode, we begin our Lift List with Safety Cues series by breaking down key strength-training exercises and explaining how each movement fits into a well-structured workout programme.   Part 1 focuses on identifying whether each exercise is a free weight, fixed resistance, or bodyweight movement, while also highlighting whether it is a compound or isolation exercise. Alongside each lift, we cover essential safety cues to help improve technique, reduce injury risk, and build confidence in the gym.   Listeners will learn how to recognise different exercise types, understand the purpose of each movement, and apply simple coaching cues for safer and more effective training.
