The Most Realistic Striking Experience — Finally, One Person Can Handle It
A water-filled punching bag delivers something no sand or filler bag can: fluid resistance, no hard spots, and joint-friendly impact absorption. The OHMY FLEX 22" 210LB Water Punching Bag is built from heavy-duty black PVC and holds up to 95kg (210lbs) of water — giving you the most authentic striking experience available.
But once filled with water, that 210LB weight is too heavy for most people to lift manually. That's why we engineered the Easy-Lift 3:1 Pulley System — a complete solution that lets one person raise and lower the bag effortlessly.
3:1 Easy-Lift Technology — Lift 210LB with Just 70LB of Effort
By combining one self-locking fixed pulley and two moving pulleys, our system creates a 3:1 mechanical advantage that reduces lifting force by two-thirds. Lifting a water-filled 210LB bag requires just 70LB of effort — easily manageable by anyone.
Patented Self-Locking Pulley — Adjust Anytime, Lock Anywhere
The self-locking fixed pulley (200KG rated) features our patented self-locking design. Unlike ordinary pulleys that require knots or cleats to hold a load, our patented mechanism locks automatically through gravity at any height:
Pull the rope — the bag rises smoothly to your desired height
Stop pulling — the pulley locks instantly, holding the bag securely exactly where you want it
Want to fine-tune? — Just lift slightly to release the lock, then lower smoothly to a new position
No buttons, no levers, no complex mechanisms — just intuitive, effortless height adjustment whenever you need it. This patented technology makes one-person operation simple and safe.
Premium Stainless Steel — Built to Last
We don't cut corners on hardware. Every pulley in this system is crafted from high-quality stainless steel:
• Self-Locking Fixed Pulley: Cast stainless steel, 15.5cm x 7cm, 750g, rated for 200KG load capacity. Combines fixed mounting with auto-lock functionality.
• Moving Pulleys (2 pcs): Precision 304 stainless steel, smooth-rolling design, each rated for 200KG load capacity — providing ample strength for your water-filled bag.
Stainless steel means no rust, no corrosion, no coating to chip or peel. These pulleys will outlast your training space.

• 6m Polyester Rope — 11.5mm diameter, black, UV and abrasion-resistant

210LB Water-Filled Bag — The Most Realistic Striking Experience
The bag itself is a 22-inch black water punching bag with a 210LB (95kg) capacity when filled with water. Water-filled bags offer:
• No hard spots — unlike sand or filler bags that settle and clump
• Joint-friendly — water absorbs impact, reducing stress on wrists and elbows
• Realistic feel — the fluid movement mimics the resistance of a real opponent
• Adjustable weight — fill to your preferred firmness (not required to be 210LB)
