Train Hard. Use It Right.
Please review these safety, setup, care, and usage guidelines before using the Core Bomb.
Improper use may result in serious injury and/or death.
Use the Core Bomb only as intended and as outlined in this guide.
Thank You for Choosing the Core Bomb
If you have any questions about the product, please contact our customer service team at info@corebomb.com.
Before first use and before every workout, inspect the Core Bomb for any signs of damage.
- The polyurethane ball should be one solid piece with no cracks or splits.
- The stainless-steel bar should be straight with no bends, cuts, or holes.
- One end should have a welded cap to prevent the ball from sliding off.
- The opposite end should have a flanged handle that can be securely screwed into place.
- The quick-release clip should fit snugly onto the bar.
Use the Core Bomb as Designed
The Core Bomb is not designed to support your entire body weight.
Use it only for push-ups, planks, rollouts, and other movements where either your hands or feet remain grounded.
Secure the Ball Before Swinging
When using the Core Bomb as a mace or swinging club, make sure the ball is firmly positioned against the welded-cap end of the bar.
- Position the quick-release clip snugly against the ball so it cannot slide.
- Make sure the flanged end cap is screwed in tightly before use.
- Maintain a secure grip on the stainless-steel bar at all times.
If you have difficulty maintaining grip, an easy-add rubber grip is recommended.
A small amount of tape may also be placed at the very end of the bar near the flanged end cap.
Adding Weight
If you add external weight to the Core Bomb for mace or club swings, do not add more than 10 pounds without using a second quick-release clip.
When using more than 10 pounds of external weight, double the clips to help keep the load securely in place during overhead swings.
Keep It Clean and Moving Smoothly
Use a soft, damp cloth for regular cleaning.
Fully remove the ball periodically and clean the inside surfaces to remove dirt and abrasive debris that could cause minor scratching or interfere with smooth movement.
Use It for Training — Not Demolition
The Core Bomb includes a lifetime warranty on the stainless-steel bar, including the flanged end cap, and the polyurethane ball under normal use.
The quick-release clip includes a 1-year warranty for personal use and a 6-month warranty for commercial use.
The Core Bomb is not intended to be used as a demolition tool.
Sledgehammer-style strikes should only be performed against a soft and/or rubberized target designed to absorb impact, such as an old tire.
Start Controlled. Progress With Confidence.
Before training, wear appropriate clothing with no loose items, hanging jewelry, or necklaces.
Make sure you have at least 10 square feet of open space around you and at least 10 feet of clear ceiling height when training indoors.
Keep children and pets away while the Core Bomb is in use, and only one person should use the device at a time.
Consult your physician before beginning any exercise program.
- Move the quick-release clip to the very end of the steel bar against the flanged end cap and lock it in place.
- Beginners should use carpet or grass to reduce the amount of roll. Only experienced users should attempt planks or push-ups on hard flooring or concrete.
- From your knees, grip the bar about shoulder-width apart and position the ball directly between your hands.
- Once the bar is under control, lift your knees from the ground and hold a plank position with your shoulders directly over your hands.
- Use a wider foot position as a beginner and narrow your stance as balance and control improve.
- Once you can hold a stable plank for 30 seconds, begin practicing push-ups by lowering your chest toward the ball and pressing back up.
- Beginners may perform push-ups from their knees.
- As your skill improves, experiment with hand placement, bar angle, and controlled side-to-side ball movement.
- Position the ball against the welded end cap and move the quick-release clip tightly against the ball.
- Confirm that the flanged end cap is tightly screwed in.
- Grip near the flanged end cap with one hand and place the other hand closer to the ball, leaving space between your hands for control.
- Stand with your feet slightly wider than shoulder width and begin swinging slowly from side to side.
- Swing through both directions under control.
- As you become more comfortable, gradually reduce the space between your hands until they are together, similar to holding a baseball bat.
- Gradually increase swing speed as control improves, but never swing at maximum speed.
- Switch hand positions regularly so both sides receive equal work.
- Always keep both hands on the bar while performing these swings.
- Once comfortable, you may progress to golf-style swings, shovels, rows, and other multiplanar movements.
Mace swings, single-arm mills, standing rollouts, and other advanced movements are not detailed in this guide.
