2. Product Features
The Everlast Omniflex Free Standing Heavy Bag is designed for dynamic training with several key features:
- High-Grade Shock-Absorbing Foam: Provides a responsive and protective striking surface.
- Nevatear Outer Shell: Engineered for lasting durability and functionality.

- Low-Profile Base Design: Facilitates a wide range of strikes, including punches, kicks, and knee strikes.
- Adjustable Height: The bag can be adjusted to a maximum height of 67 inches to accommodate various user heights and training preferences.
- Fillable Base: Designed to be filled with water or sand, providing approximately 130 lbs of stability when filled with water.
3. Package Contents
Please verify that all components are present before beginning assembly:
- Heavy Bag Striking Surface
- Adjustable Pole/Shaft
- Omniflex Spring Mechanism
- Base Unit
- Assembly Hardware (bolts, washers, adjustment knob, Allen wrench)
4. Setup Instructions
Follow these steps carefully for proper assembly:
- Unpack Components: Carefully remove all parts from the packaging and lay them out on a clean, flat surface. Ensure all components listed in Section 3 are present.
- Assemble the Pole and Spring: Attach the Omniflex spring mechanism to the bottom end of the adjustable pole. Secure it firmly using the provided bolts and washers. Use the Allen wrench to tighten.
- Attach Striking Bag: Secure the heavy bag striking surface to the top end of the adjustable pole. Ensure it is aligned correctly and fastened tightly with the designated hardware.
- Connect to Base: Insert the assembled pole and spring into the central opening of the base unit. From the underside of the base, secure the pole using the remaining bolts and washers. Tighten all connections securely.
- Fill the Base:
- Option A (Water): Remove the fill cap located on the base. Use a garden hose or a large funnel to fill the base with water. The base holds approximately 130 lbs of water. Fill until the water level is just below the opening. Securely tighten the fill cap to prevent leaks.
- Option B (Sand): For maximum stability, sand can be used. This process is more labor-intensive. Use dry, fine-grain sand (e.g., pool filter sand) and a large funnel. It is recommended to have assistance for tilting and rolling the base during filling to ensure even distribution and full capacity. Securely tighten the fill cap after filling.
- Adjust Height: Loosen the adjustment knob on the adjustable pole. Raise or lower the heavy bag to your desired training height. Once set, tighten the knob securely to lock the bag in position.

5. Operating Instructions
To ensure a safe and effective workout:
- Stability Check: Before each use, confirm that the base is fully filled and stable, and all connections are tight.
- Protective Gear: Always wear appropriate boxing gloves to protect your hands and wrists from injury.
- Dynamic Training: The Omniflex neck allows the bag to move and react to strikes, providing a dynamic, reflex-like workout. This movement is an intended design feature.
- Strike Variety: Utilize the low-profile base design to practice a wide range of strikes, including punches, kicks, and knee strikes.
6. Maintenance
Regular maintenance will extend the life of your heavy bag:
- Cleaning: Wipe the striking surface with a damp cloth and mild soap as needed to remove sweat and dirt. Avoid using harsh chemicals or abrasive cleaners, which can damage the Nevatear material.
- Hardware Check: Regularly inspect all bolts and connections, particularly the three screws holding the pole at the bottom and the two bolts at the base of the spring. Tighten them as necessary before each session to prevent loosening due to vibrations.
- Base Integrity: Periodically check the base for any signs of cracks or leaks. If using water, ensure the fill cap remains tightly sealed.
- Storage: Store the heavy bag in a dry, temperate environment. Avoid prolonged exposure to direct sunlight, extreme temperatures, or excessive moisture, which can degrade materials.
7. Troubleshooting
Common issues and their solutions:
- Issue: Bag moves excessively or tips over during use.
Solution: Ensure the base is completely filled with water or sand to its maximum capacity (approximately 130 lbs with water). Verify the fill cap is securely closed. Insufficient weight in the base is the primary cause of instability. - Issue: Assembly bolts loosen during use.
Solution: This is a common occurrence due to vibrations from striking. Regularly check and tighten all assembly bolts, especially those connecting the pole to the base and the spring mechanism, before each training session. For a more permanent solution, consider applying a thread-locking compound (e.g., Loctite, not provided) to the bolt threads, though this may make future disassembly more difficult. - Issue: Bag swings too much after strikes.
Solution: This is an intended feature of the Omniflex design, providing a reflex-like workout that challenges timing and footwork. It is normal for the bag to move dynamically. Adjust your striking technique to control the bag's rebound, or incorporate dodging and weaving into your routine to adapt to its movement.
