Optional progressions / 3 EXERCISES

Basic Core Exercises

Progress at a level that suits your ability. These exercises are optional; seek individual guidance where needed.

Choosing your support and starting level

General instructions for the following exercises: Beginners should perform the following exercises with their body nearly in a vertical position (leaning on a tall counter). As you become stronger, set your body closer to a horizontal position (doing the exercises against a lower stable surface until you are strong enough to do the exercises on the floor). Be sure to breathe freely and deeply during each exercise. When holding a position, align your head and neck with your back, keep your body straight, steady and firm.

Please note: you may find it more comfortable to lean on your elbows instead of your hands.

ILLUSTRATION 01

Back Core

Repetitions & holds

5 repetitions · holds start at 2 seconds, building to 5 seconds

Place your hands on the surface you use for this exercise, with your stomach facing up. Keep an approximately 90-degree angle between your arms and your chest/trunk. Keep your body straight, with your head and neck in line with your trunk. As your ability develops, gradually use a lower support, progressing towards performing the exercise on the floor.

ILLUSTRATION 02

Front Core

Repetitions & holds

5 repetitions · holds start at 2 seconds, building to 5 seconds

Place your hands on the surface you use for this exercise, with your stomach facing down. Keep your arms at approximately 90 degrees to your chest, with your body straight and your head and neck in line. Start with a stable support at a comfortable height, such as a kitchen bench. Gradually use a lower support as your strength develops.

ILLUSTRATION 03

Side Core

Repetitions & holds

5 repetitions per side · alternate sides · holds start at 2 seconds, building to 5 seconds

You may want to use your free hand to hold on to an object in front of you (a chair), as this exercise will challenge your stability. With your left side down, support yourself through your left forearm and elbow on a stable surface, rather than through your hand. Keep your upper arm at approximately 90 degrees to your chest. Keep your body straight, with your head and neck in line and without rotating your head. Rest your right arm along the side of your body when not using it for optional support. Then repeat the exercise with the opposite side.

Side Core · optional chair assistance
Optional assisted side-core demonstration: the forearm and elbow support the body on a stable surface, while the free hand holds a chair for additional stability.
