You shouldn’t do the same exercises every day… while that sentence holds truth in most conversations, some exercises can be performed every day, and are even encouraged to – walking, for example. But here we are talking about the best 3 core exercises that you can, and should, do every day for better strength and stability.
Core stability is a crucial aspect of fitness that often goes overlooked. Unlike dynamic core exercises that involve a lot of movement, core stability exercises focus on limiting excessive or unwanted motion at the spine. This stability is essential for anyone looking to improve their performance in key gym exercises such as squats, deadlifts, bench presses, and even more complex movements like cleans and snatches. By incorporating these stability exercises into your routine, you’ll not only enhance your strength but also reduce the risk of injury, ensuring your spine remains resilient under load.
One of the most effective ways to achieve core stability is through the McGill Big Three, a set of exercises developed by Dr. Stuart McGill, a renowned back expert. Dr. McGill has dedicated his career to studying the spine and developing methods to prevent and rehabilitate spinal injuries.
His research has shown that stabilizing the spine and understanding its mechanics are key to avoiding common back issues. The McGill Big Three exercises are designed to brace the spine, lock it into place, and allow movement to occur around the hips instead, providing a solid foundation for all your physical activities.

To help you with that and the 3 best core exercises to do every day, we lean into the expertise of Dr Aaron Horschig.

So let’s check out the 3 best core exercises to do every day for strength and stability.

Best 3 Core Exercises to Do Every Day for Strength and Stability
The McGill Big Three consists of the curl-up, the side plank, and the bird dog. These exercises specifically target different parts of the core, ensuring a comprehensive approach to stability.
Unlike traditional ab workouts that involve flexing the spine, these exercises emphasize maintaining a neutral spine position and activating the core muscles to hold it steady. By practising the McGill Big Three regularly, you can expect to feel more powerful and stable during your workouts, leading to improved performance and reduced likelihood of injury.
These exercises aim to limit excessive or unwanted motion at the spine, ensuring better stability and resilience under load. Let’s dive into each of these exercises:
1. The Curl-Up
Objective: Strengthen the front of the core without moving the spine.
Instructions:
- Lie on your back with one leg bent and the other straight.
- Place your hands under your lower back to monitor movement.
- Brace your core by tightening the abdominal muscles.
- Slightly lift your head and shoulders off the ground, holding this position for 10 seconds.
- Return to the starting position and repeat for six reps.
Tips:
- Keep your head and shoulders low to avoid straining your neck.

Integrating the 3 Best Core Exercises into Your Routine
Incorporating the McGill Big Three into your daily routine is essential for enhancing core stability and overall gym performance. These exercises should be performed regularly to maximize their benefits. Start by including them at the beginning of your workout as part of your warm-up routine. This ensures that your core is activated and ready to support your spine during heavier lifts.
Begin with the curl-up exercise, which targets the front of the core without flexing the spine. Hold this position for 10 seconds before lowering back down. Repeat this for six reps, ensuring your lower back remains neutral throughout the exercise.
Next, move on to the side plank, which strengthens the lateral core muscles and the glute medius. Hold this position for 10 seconds before lowering back down. Perform six reps on each side, maintaining proper form to avoid any twisting or sagging of the hips.
Finally, incorporate the bird dog exercise, which targets the back of the core and improves coordination between the upper and lower body. Hold this position for 10 seconds before returning to the starting position. Switch sides and repeat for six reps on each side. Focus on slow, controlled movements to maintain stability and prevent any unwanted motion in the spine.
