Medicine ball exercises develop the core differently from standard ab exercises and that difference matters. A crunch, a plank, and a hollow body hold all develop core strength through static or slow movements. A medicine ball slam, a rotational throw, and a woodchop develop core power: the ability to produce force rapidly through the trunk in the rotational, flexion, and extension patterns that determine athletic performance.
A complete core training programme includes both strength and power. The medicine ball provides the power component that bodyweight exercises cannot replicate.
Why Medicine Balls Are Specifically Effective for Core Training
Rotational loading: Most ab exercises load the core in the sagittal plane (forward-backward: crunches, leg raises, planks). The core must also produce and resist force in the transverse plane (rotational: throwing, swinging, hitting). Medicine balls allow rotational loading that develops this transverse plane core power.
Throwing mechanics: When a medicine ball is thrown or slammed, the core must accelerate the load rather than merely holding position against it. This acceleration training specifically develops the explosive core function that transfers to athletic power sports.
Anti-rotation development: When a medicine ball is caught after a throw, the core must instantly absorb and resist the rotational and impact forces. This reactive anti-rotation develops the core’s protective function against sudden external forces.
Load variety: Medicine balls come in weights from 2 to 20 kilograms, allowing progressive overload through the same movement patterns. This progressive overload is not available from bodyweight-only core exercises.
Medicine Ball Ab Exercises by Movement Pattern
Category 1: Rotational Exercises
Rotational exercises develop the obliques and the transverse plane core power most relevant to throwing, hitting, kicking, and all rotational sport skills.
Medicine Ball Rotational Throw (Against Wall)
The primary rotational power exercise.
How to do it:
- Stand perpendicular to a solid wall with the feet shoulder-width apart
- Hold the medicine ball with both hands at hip height on the side away from the wall
- Rotate the hips and trunk explosively toward the wall, throwing the ball against it
- Catch the rebound and immediately rotate back to repeat
- Complete all reps on one side before switching
Muscles targeted: Obliques (internal and external), transverse abdominis, hip rotators, serratus anterior
Sets and reps: 3 sets of 8 to 10 per side
The rotational throw cue: The rotation should be initiated by the hips, not the arms. Think of the arms as connectors that transfer the rotational force from the hips to the ball rather than as the primary power producers. Hip-initiated rotation produces significantly more force than arm-dominated throwing.
Medicine Ball Woodchop
A diagonal rotational movement that develops the obliques through a large range of motion.
How to do it:
- Hold the medicine ball with both hands above one shoulder
- Rotate and drive the ball diagonally downward toward the opposite hip in a chopping motion
- Follow through until the ball is near the opposite hip or thigh
- Return to the starting position under control
- Complete all reps on one side before switching
Variation — Low to High: Reverse the pattern, starting with the ball near one hip and driving it diagonally upward toward the opposite shoulder. This variation emphasises the lower obliques in the initial phase.
Sets and reps: 3 sets of 10 to 12 per side
Russian Twist With Medicine Ball
A seated rotational exercise developing the obliques through a shorter range at a higher rep range.
How to do it:
- Sit on the floor with knees bent and feet either flat on the floor (easier) or raised (harder)
- Lean the torso back to approximately 45 degrees
- Hold the medicine ball at chest height
- Rotate the torso to one side, tapping or moving the ball to the floor beside the hip
- Rotate to the other side
- One rotation to each side equals one rep
Sets and reps: 3 sets of 20 (10 per side)
Seated Rotation Pass (Partner)
A partner-based rotational exercise that adds a throwing-catching element to the seated rotation.
How to do it:
- Sit back-to-back with a partner with knees bent
- One person holds the medicine ball and rotates to pass it to the partner on one side
- The partner receives it on the same side, rotates to the other side, and passes back
- This creates a continuous rotational circuit
Sets and reps: 3 sets of 20 total passes (10 per direction)
Category 2: Anti-Rotation and Stabilisation Exercises
These exercises develop the core’s ability to resist rotation and maintain stability against external forces.
Medicine Ball Pallof Press
One of the most effective anti-rotation core exercises, using a medicine ball in a cable or band position against a wall or with a partner.
Partner version (most accessible):
- Stand perpendicular to a partner
- The partner holds the ball and presses it against your hands at chest height, providing a sideways resistance
- Press the ball straight out from your chest and hold for 2 to 3 seconds
- Return to the chest
- The core resists the rotational force created by the sideways resistance
Sets and reps: 3 sets of 10 per side
Medicine Ball Single-Leg Stand
Holding a medicine ball while balancing on one leg develops the core stabilisation required for single-leg athletic stance.
How to do it:
- Stand on one leg
- Hold the medicine ball at chest height
- Rotate the ball and trunk to one side, then the other
- The standing leg and core must stabilise against the rotational movement of the ball
- Complete 30 seconds per side
Sets: 3 per side
Category 3: Flexion Exercises
Flexion exercises develop the rectus abdominis (the six-pack muscle) and the hip flexors through the forward-bending core movement.
Medicine Ball Crunch
The weighted version of the standard crunch, adding progressive overload to the basic movement.
How to do it:
- Lie on the back with knees bent
- Hold the medicine ball at the chest or extended overhead
- Crunch the torso upward toward the knees
- Hold briefly at the top
- Lower slowly
Overhead variation (more demanding): Holding the ball overhead with arms extended increases the lever arm, significantly increasing the rectus abdominis demand.
Sets and reps: 3 sets of 15
Medicine Ball Sit-Up to Chest Pass
Combines the sit-up with an explosive chest pass, developing both core strength and upper body power simultaneously.
How to do it:
- Lie on the back with knees bent, a partner at the feet
- Hold the medicine ball at the chest
- Perform a full sit-up
- At the top of the sit-up, explosively chest pass the ball to the partner
- The partner returns the ball and you lower back to the floor
- Catch the ball on the way down and repeat
Sets and reps: 3 sets of 10
V-Up Pass
An advanced core exercise combining hip flexion with a partner pass.
How to do it:
- Lie on the back with the ball held overhead
- Simultaneously lift the legs and the torso to form a V shape
- Pass the ball to a partner at the peak of the V
- Lower back to the floor
- Receive the ball from the partner and repeat
Sets and reps: 3 sets of 8 to 10
Medicine Ball Leg Raise
Using the medicine ball between the feet adds resistance to the standard leg raise.
How to do it:
- Lie flat on the back
- Hold a medicine ball between the feet (gripping with the inner arches)
- Raise the straight legs toward the ceiling against the additional weight
- Lower slowly under control
- Do not allow the lower back to arch during the lowering phase
Sets and reps: 3 sets of 10 to 12
Category 4: Anti-Extension Exercises
Anti-extension exercises develop the core’s ability to resist extension forces: the core quality most relevant to posture, lower back protection, and overhead stability.
Medicine Ball Rollout
The medicine ball version of the ab wheel rollout, one of the most demanding anti-extension core exercises.
How to do it:
- Kneel on a mat with the medicine ball in front
- Place both hands on top of the medicine ball
- Roll the ball forward by allowing the arms to extend overhead
- Keep the hips extended (no hinging at the hips)
- Roll as far forward as control allows, then pull the ball back
Sets and reps: 3 sets of 8 to 10
Medicine Ball Dead Bug
The dead bug (as covered in the exercise for psoas muscle strengthening article on this site) with a medicine ball adds load to develop the anti-extension core quality with greater demand.
How to do it:
- Lie on the back with knees at 90 degrees above the hips
- Hold the medicine ball between the knees and the hands (pressing inward from both directions)
- Slowly lower one leg toward the floor while maintaining the ball position
- Return and alternate
- The ball pressing creates an irradiation effect that increases overall core activation
Sets and reps: 3 sets of 8 per side
Category 5: Power and Plyometric Exercises
These exercises develop core power through explosive movements that cannot be replicated with bodyweight.
Medicine Ball Slam
The most fundamental core power exercise, developing the explosive flexion and extension that transfers to overhead throwing and overhead athletic movements.
How to do it:
- Stand with feet shoulder-width apart
- Hold the medicine ball with both hands
- Raise the ball overhead by extending the hips and arms
- Slam the ball downward toward the floor with maximum force, simultaneously flexing the trunk
- The slam should be a total body movement: legs, hips, trunk, and arms all contributing
- Catch the ball on the bounce or pick it up and repeat
Which ball to use: A slam ball (as covered in the slam ball vs medicine ball article on this site) is designed to not bounce and is appropriate when catching the rebound is not desired. A standard medicine ball bounces and is used when a catch-and-repeat pattern is preferred.
Sets and reps: 3 to 4 sets of 8 to 10
Overhead Medicine Ball Throw (Wall)
Develops the core extension power relevant to overhead throwing sports.
How to do it:
- Stand facing a wall with feet shoulder-width apart
- Hold the ball at the chest or overhead
- Drive the ball forward and upward toward the wall with maximum force
- Catch the rebound
- Repeat explosively
Sets and reps: 3 sets of 8
Medicine Ball Burpee
A total body power exercise combining the standard burpee with medicine ball handling.
How to do it:
- Hold the medicine ball at the chest
- Squat down and place the ball on the floor
- Jump the feet backward to a push-up position with the hands on the ball
- Perform a push-up on the ball
- Jump the feet forward
- Stand and drive the ball overhead explosively
- Lower and repeat
Sets and reps: 3 sets of 8 to 10

Programming Medicine Ball Ab Workouts
Frequency: 2 to 3 times per week as a dedicated core session, or integrated into the end of lower or upper body training sessions.
As a standalone core session:
The complete workout above, 2 to 3 times per week, provides comprehensive core development.
Integrated into training sessions:
- After lower body training: 2 to 3 medicine ball core exercises, 3 sets each
- After upper body training: Rotational throws and slams pair naturally with pressing and pulling sessions
Progressive overload:
- Increase ball weight by 1 to 2 kilograms when all prescribed reps can be completed with full explosive intent
- Add one additional set every 2 to 3 weeks before increasing load
- Introduce more demanding variations (V-up pass, medicine ball burpee) as strength and coordination develop
Frequently Asked Questions
What weight medicine ball should I use for ab exercises?
The appropriate weight depends on the exercise and the goal. For power exercises (slams, rotational throws), lighter balls (3 to 6 kilograms) allow greater velocity and better develop explosive power. For strength exercises (weighted crunches, rollouts), heavier balls (6 to 12 kilograms) provide the progressive overload needed for strength development. Begin lighter than expected, particularly for rotational exercises where the rotational force can be significant.
Are medicine ball ab exercises better than regular ab exercises?
They develop different qualities rather than one being universally better. Standard ab exercises (planks, leg raises, crunches) develop core strength and endurance effectively. Medicine ball exercises add the power and rotational components that standard exercises cannot provide. A complete core programme includes both.
Can I do medicine ball ab exercises every day?
Low-intensity medicine ball core work (light Russian twists, woodchops) can be performed daily. High-intensity power exercises (slams, rotational throws) produce significant neuromuscular fatigue and benefit from 48 hours of recovery. A practical approach is daily low-intensity core activation with 2 to 3 higher-intensity medicine ball sessions per week.
Do medicine ball ab exercises help with lower back pain?
Core strengthening exercises are a component of lower back pain management, but medicine ball exercises specifically should be introduced carefully for people with lower back pain. The rotational and flexion exercises are generally appropriate and beneficial when performed correctly. High-load slams and explosive throws should be introduced gradually and within pain tolerance. Anyone with significant lower back pain should seek physiotherapy assessment before beginning a medicine ball core programme.
