A Beginner’s Guide to Foundational Exercises: Building a Stronger You

Introduction: Why a Solid Foundation Matters

As an athletic development coach, I often use an analogy from architecture to explain the importance of foundational training. Imagine building a structure with bricks. If you rush to build it as high as possible without ensuring the base is solid, the structure will eventually fail. However, if you take the time to build a stable and solid foundation, you create something strong that can be built upon safely.

Your body is no different. This guide is designed to introduce you to key exercises that build a strong, stable foundation for any physical activity. Mastering these movements will not only help you improve your performance but will also be your best defence against common injuries. Let’s get started on building a stronger you.

--------------------------------------------------------------------------------

1. Protecting Your Knees: The Power of Control

The knee is what’s known as a “hinge joint,” just like an elbow or a door hinge. It’s designed to bend efficiently in one primary direction (forward and back). When the knee is forced to rotate or move sideways under pressure, especially during sports, the risk of injury increases significantly. The following exercises are designed to train the muscles around the knee to maintain proper alignment and control.

1.1. The Hop and Hold

The primary purpose of the Hop and Hold is to improve knee control by strengthening the muscles that support and stabilise the joint. To get the most out of this drill, focus on these critical technique points:

1. Target Knee Angle: The goal is to land with a knee angle between 30 and 45 degrees. This specific range is the training zone where the muscles around the knee are most challenged, forcing them to work to build control. Landing too high doesn’t provide the same benefit.

2. Knee and Toe Alignment: It is crucial that your knee stays directly in line with your toe upon landing. You must actively prevent the knee from collapsing inwards (a common issue known as knee valgus).

3. Control is Key: This principle of controlled landing applies whether you are hopping forward, sideways, or as part of a turn. The focus is always on a stable, aligned landing.

1.2. The Lateral (Sideways) Lunge

This is an essential exercise for anyone playing multi-directional sports like football, rugby, basketball, or tennis, where changing direction quickly is a key skill. A major focus of the lateral lunge is learning to change direction efficiently and safely. Here’s the difference between a healthy and an unhealthy movement pattern:

Pushing: Initiate the movement by forcefully pushing the foot into the ground to accelerate (healthy).

Dragging: Plant the foot and then drag the rest of the body, which is unhealthy for the knee (unhealthy).

To perform this move correctly, keep these coaching points in mind:

• Initiate with a “Push”: The movement should always start with a powerful push of the foot into the ground.

• Keep Feet Parallel: Keeping your feet parallel throughout the movement helps train the adductor (groin) muscles. More importantly, it keeps you in a ready position. If you turn your foot out, the only way you can go is in that direction, making you predictable. Parallel feet give you options.

• Maintain Knee Control: The leg you push off from is for acceleration, while the bent leg is working on braking your momentum under control. The knee of this braking leg must face the same direction as your toe and never collapse inwards.

Progressions for this exercise, such as adding a resistance band around your knees, directly target your hip muscles. This provides a perfect link to our next topic, because strong and mobile hips are crucial for providing the support your knees need.

--------------------------------------------------------------------------------

2. Building Your Base: Hip Strength and Mobility

Controlling the hips is one of the most critical factors in preventing lower limb injuries. When the muscles around the hip are weak, the hip can shift or drop when you plant your foot. This instability causes the knee to rotate inward, creating a powerful “shearing force on your knee.” These exercises are designed to build that essential hip control.

2.1. The Hip Series (Part 1)

This series of drills strengthens the muscles around the hip girdle, training them to prevent the hip from shifting when you run, jump, or land. Perform the following sequence of leg movements on one side before switching to the other, aiming for a controlled pause at the top of each lift.

1. Lift leg forward (aiming for parallel to the floor) and pause.

2. Lift leg to the side and pause.

3. Lift leg behind and pause.

The single most important coaching point for this series is: “Don’t swing.” It’s better to do it lower with a controlled pause than to swing the leg high without any control.

2.2. Happier Hips Sequence (Thanks to Steve Myrland for showing me this).

This sequence is designed to develop both hip and hamstring mobility, helping them become both “strong and long.”

• Stance: Begin with your feet wider than shoulder-width apart, with both feet facing forward.

• No Collapsing: Never let the knee of the supporting leg collapse inward. This is the same principle of knee alignment we discussed in the first section—it starts at the hips and is essential for protecting the joint. Keep that leg “strong and long.”

• Tension in Feet: Press your feet firmly into the ground, “almost like they’re gripping,” to maintain tension and stability.

The core exercise involves shifting your hips from side to side while reaching down towards the ground. As your mobility improves, you can progress from simply touching the ground to reaching behind your heels.

Once you’ve built this foundational hip control, you can begin to challenge your body with more complex movements that integrate both the upper and lower body.

--------------------------------------------------------------------------------

3. Full-Body Coordination and Strength

After establishing control at the knee and hip, the next step is to challenge your body with more varied movements. The following exercises require coordination between your upper and lower body, which is essential for athletic performance.

3.1. The Squat Matrix (thanks to Kelvin Giles for showing me this).

The Squat Matrix is a dynamic way to practice the squat in the many different foot positions that can occur during sports. Frankly, it’s a bit more interesting than just doing 40 standard squats in a row. The sequence involves performing squats in eight different stances:

1. Normal Squat

2. Feet Together

3. Feet Wider than Hips

4. Feet Super Wide

5. Staggered Squat (Right Foot Forward)

6. Staggered Squat (Left Foot Forward)

7. Cross-Legged (Right over Left)

8. Cross-Legged (Left over Right)

To make the matrix more challenging, you can add “funky arms”—making different symmetrical or asymmetrical shapes with your arms to purposely get yourself off balance and challenge your stability. For an even greater challenge, try performing the sequence with your eyes shut.

3.2. Walking Medicine Ball Series (thanks to Vern Gambetta for showing me this).

This series trains an athlete’s ability to separate the movements of their upper and lower body. This skill is critical in sports like rugby, netball, or soccer, where you might need to pass a ball or push off a defender while your lower body is moving. The series uses three main rotational patterns with a medicine ball:

• Loop: A circular motion with the ball, like a loop.

• Side-to-Side: A tight rotation with the ball close to the body or a long rotation at full arm’s length.

• Figure of Eight: A “kayaking” action that moves the ball above the head and then below the knees.

It is very important that an athlete can lunge forwards and backwards safely and with good control before adding the complexity of the medicine ball movements.

These exercises build general athletic capacity. Now, let’s address a specific problem created by our modern lifestyles.

4. Counteracting Modern Life: The Three Uncommon Postures (thanks to Dr Ed Thomas for showing me this).

Most of our daily lives are spent in just a few positions: upright, flexed (like sitting on a sofa or at a desk), or lying down. This is also true for sports like cycling or rowing, where you are flexed a lot. Our bodies become accustomed to these limited postures. By intentionally training “uncommon postures,” we can counteract these effects and help keep our spines healthy and mobile.

Extension:

Bending backwards, the opposite of a flexed or slouched position.

Brachiation:

Hanging from the arms or feet (using boots).

Inversion:

Being upside down.

Here are simple, beginner-friendly ways to incorporate these postures into your routine.

4.1. Extension Exercises

• Watching TV while lying on your stomach.

• The Scorpion exercise (lying on your stomach and rotating one leg over your body to combine back extension and rotation).

4.2. Brachiation (Hanging) Exercises

• Simply hanging from a pull-up bar with straight arms.

• Hanging with your feet on the floor as an anchor and rotating your body left and right.

4.3. Inversion (Upside Down) Exercises

• Placing your feet on a Swiss ball and walking your hands back and forth.

• Doing a handstand against a solid wall for support.

By building a strong foundation and exploring a wide range of movements, you prepare your body for anything life throws its way.
