Core stability training is about learning to resist unwanted movement. When your core muscles fire correctly, they protect your spine, reduce back pain, and improve how you move, balance, and hold yourself. According to the American Council on Exercise (ACE), developing core strength is essential for everyday health and well-being, and the most important thing to remember is to avoid using momentum. Instead, perform each exercise with awareness so that the core muscles stay engaged throughout.
This guide walks you through seven core stability exercises from ACE, explains the bracing technique that underpins safe core work, and shares a warm-up circuit that progresses from stabilization to movement. You will also find tips for controlling your low back during the bird dog and a checklist to keep your training safe and effective. For a broader look at how stability fits into core training, see our article on core training explained.
Seven Core Stability Exercises to Resist Unwanted Movement
ACE fitness expert Elizabeth Kovar outlines seven exercises that challenge your ability to hold a stable position while your limbs move. Each exercise includes an alternate version if the main version feels too challenging. If you do not have the equipment mentioned, use your own body weight.
BOSU Bird Dog
Focus: Core stability. Set your left knee on the center of the BOSU dome and place both hands on the floor under your shoulders. Extend the right leg behind you to hip height, keeping the foot flexed. Raise the left arm to shoulder height with your thumb facing the ceiling. Hold for 20 seconds, then switch sides. Alternate version: Perform the exercise on the floor.
Supine Heel Taps
Focus: Core stability. Lie on your back with your arms by your sides. Engage the abdominals and draw the navel toward your spine. Lift the knees to 90 degrees. With control, lower your right foot to touch the floor with your heel, then return it to 90 degrees. Repeat with the left leg and continue alternating. Perform 10 repetitions with each leg. Each repetition should take about four seconds: two seconds to lower the leg and two seconds to raise it back. Alternate version: Keep your feet on the floor and slide your heel on the mat, alternating legs.
Marching Glute Bridge
Focus: Lumbo-pelvic stability. Lie on your back with your hands by your sides. Lift your hips and hold a glute bridge. Lift the right foot off the floor to 90 degrees at the hip and knee. Return the foot to the floor, then lift the left foot to 90 degrees and return to center. Keep the hips lifted and maintain a neutral pelvis as you alternate leg lifts for 20 repetitions. Alternate version: Hold a static glute bridge with both feet on the floor for 30 or more seconds.
Stability Ball Dead Bug
Focus: Core stability. Lie on your back and lift your knees to 90 degrees. Place a stability ball at the knees and press your hands and legs into the ball. Engage the core muscles and draw the navel toward the spine. Extend the left arm and right leg while continuing to hold the ball with your left leg and right hand. The straighter the limbs, the more challenging the exercise. Make sure the knees stay at 90 degrees when returning to center; letting the calves touch the hamstrings makes the exercise easier. Complete 10 repetitions on each side, alternating which arm and leg are extended with each repetition. Alternate version: Perform the exercise without a stability ball and keep your knees at 90 degrees as you lower. This is similar to the Supine Heel Taps but with the addition of the arms.
Forearm Plank with Toe Taps
Focus: Core stability and hip strength. Position your body into a forearm plank with your arms resting on the dome side of a BOSU balance trainer. Begin alternating lateral toe taps: the right foot pushes away from the body, touches the floor, and then returns to center. Repeat with the left leg. Complete a set of 10 repetitions on each leg. Alternate version: Perform a static forearm plank with feet hip-distance apart and the forearms on the floor.
Side Plank with Torso Rotation
Focus: Core strength and shoulder stability. Position your body into a forearm side plank with both legs extended. Lift the top arm over the chest and then rotate with your rib cage to draw the hand underneath the ribs. Repeat this motion for 10 to 12 repetitions, then perform on the other side. Alternate version: Perform the exercise in a modified side plank with your bottom shin on the floor.
Single-Leg Deadlift
Focus: Posterior chain strength. Hold a set of dumbbells and stand tall with feet hip-distance apart. Lift the right foot off the floor and hinge the pelvis to glide over the top of the left leg. The head and the foot should counterbalance each other. The lowest hinging point should be when the body is parallel to the floor. Keep the pelvis as neutral as possible. Complete 12 repetitions on each leg. Alternate version: Perform the exercise without dumbbells or complete a deadlift with both feet on the floor.

Bracing: The Foundation of Core Stability
Before you move, you need to create stiffness. ACE’s exercise library describes this as bracing: you stiffen your torso by contracting your abdominal and core muscles. In the reverse crunch, for example, you gently exhale, stiffen your torso, and then lift your feet off the floor while maintaining that tension. Another ACE article, “Train This, Not That: The Core Edition,” explains bracing as tightening your core muscles as if you were about to be punched in the stomach.
Bracing is central to the McGill curl-up, one of the exercises recommended by spine biomechanics researcher Dr. Stuart McGill. Unlike a traditional crunch, the McGill curl-up keeps the lumbar spine still. To perform it, lie flat on your back with only one knee bent. Place your hands under the small of your back to monitor movement, ensuring your back does not press into the floor. Brace your core, then lift your head and the tops of your shoulders while keeping your spine in neutral. For an added challenge, lift your elbows off the floor. ACE suggests trying this for six to 10 holds, each lasting 10 seconds.
Bracing also applies to the bird dog and side bridge. In the bird dog, you find a neutral spine and gently brace the core before extending your limbs. In the side bridge, you line up your elbow, shoulder, hip, and heel, brace tightly, and push the ground away from you. Hold for 10 seconds and repeat four to six times. To reduce intensity, perform the side bridge from the knees. These techniques help you build stability without placing excessive stress on the spine.

A Warm-Up Circuit That Progresses from Stabilization to Movement
ACE fitness expert Pete McCall recommends a total-body warm-up that starts with core stabilization exercises and then adds movement. This circuit gradually increases intensity and prepares your body for resistance training or other physical activity. If you are short on time, doing two sets of two core and two bodyweight-movement exercises can be effective, but adding more sets helps ensure you are completely warmed up.
Perform the following exercises in order, resting as noted:
- Hip bridge: 2 sets of 10–12 reps, 30 seconds rest between sets. This increases glute activity and stretches the hips and low back.
- Bird-dog: 2 sets of 10–12 reps, 30 seconds rest between sets. This stabilizes the spine while the arms and legs move.
- Plank: Hold for 20–45 seconds, rest 30 seconds, repeat. Engages muscles that stabilize the lumbar spine and shoulders.
- Side plank: Hold for 20–45 seconds, rest 30 seconds, repeat on the other side. Engages lateral core stability and shoulder stabilizers.
- Side lunge: 12–15 repetitions on each side, rest 45 seconds, 2 sets. Develops hip and outer thigh muscles.
- Push-ups: 2 sets of 6–10 reps, 45 seconds rest between sets. Modify as needed.
- Bodyweight squats: 2 sets of 12–15 reps, 45 seconds rest between sets. Keep the chest up, sink back into the hips, and press through the feet to stand.
This sequence moves from holding steady positions to dynamic lower- and upper-body movements. Once you learn it, you can use it as a warm-up or, by adding more reps and sets, turn it into a total-body workout when you are traveling without equipment.

Controlling the Low Back During the Bird Dog
The bird dog is an excellent exercise for teaching your body how to stabilize the lumbar spine during arm and leg movement. According to ACE’s exercise library, the degree of hip extension and shoulder flexion you can achieve is determined by your ability to control against movement in the low back. As you raise your leg, you might notice an increase in lumbar lordosis, or low back sagging. Only raise your limbs to heights where the low back position can be maintained through the combined actions of your core and abdominal muscles.
To help monitor this, you can place a light bar across your hips, parallel to your waistline, or across your shoulders. This provides visual feedback on any rotation or tilting. Your head should stay aligned with your spine throughout the movement. Never exceed your body’s capacity to control movement in the low back. If you need back-friendly alternatives, explore our back-friendly modifications.
Core Stability Checklist
Use these reminders to get the most from your core stability exercises while staying safe:
- Engage your core before you move. Brace as if preparing for a light punch to the stomach.
- Avoid momentum. Move slowly and with control, especially during the lowering phase.
- Keep your spine neutral. Avoid excessive arching or rounding, particularly in the low back.
- Stop if you feel pain.
- Progress gradually. Start with the alternate version of an exercise if the main version is too challenging.
- Use equipment only as directed. If you do not have a BOSU, stability ball, or dumbbells, use your body weight.
- Breathe normally. Do not hold your breath during holds or movements.
Frequently asked questions
Can core stability exercises reduce belly fat?
No. Core exercises train the muscles of the trunk; they do not reduce fat in one specific area.
How often should I do core stability exercises?
ACE suggests adding core stability exercises to your current workout routine, and its warm-up circuit can be used before each strength session.
Are these exercises safe if I have back pain?
Core training is not a treatment for back pain. If you have back pain, an injury, or a medical condition, speak with a doctor or physical therapist before trying new exercises. Stop any movement that causes pain, and consider working with a qualified professional who can tailor exercises to your needs.
