Adjustable Multi Horn

Adjustable Multi Horn Core Product

The Adjustable Multi Horn takes the classic triple weight horn idea and reimagines it from the ground up. Instead of being locked into a single resistance profile, you control how the load hits you at every point in the rep — start, mid-range, finish, or all three.

By changing arm angle, horn position, and horn configuration, you can engineer the resistance curve you want, whether you're chasing brutal overload or smooth, joint-friendly tension.

Key Features

• Adjustable Arm Angles: Tilt each arm to shift resistance into different phases of the lift. Emphasize the bottom, mid-range, or top of the rep by simply changing the angle.
• Movable Weight Horns: Slide each horn up or down the arm to adjust torque relative to the pivot point. Plates farther from the pivot feel heavier and more aggressive; plates closer feel smoother and more controlled.
• Modular Horn Configuration: Run triple- or double-horn setups in seconds. Use all three horns for full-range loading, or remove the front or back horn to reduce starting weight and completely reshape the loading curve.

Why It’s in a League of Its Own

Traditional single-horn systems restrict your options. Fixed triple-horn systems only give you basic start/mid/finish biasing.

The Adjustable Multi Horn gives you control in three dimensions:

• Angular control — adjust arm angles to shift which phase of the rep gets overloaded.
• Positional control — move weight horns to change torque and “feel” rep by rep.
• Configuration control — choose double or triple horn setups instantly for different loading curves.

No other horn system gives you this level of freedom over how resistance shows up across the entire range of motion.

Engineered for Versatility

• For Use With: Fully compatible with the Bulletproof ISOLATOR.
• Adapters (Optional): Adapters make it work with most major jammer arm systems.

Choose the ISOLATOR version, the Jammer Arm version, or both — and keep the same familiar, tunable feel across your favorite movements.

Built-In Counterweight (Isolator Version)

When paired with the ISOLATOR, the Adjustable Multi Horn uses a built-in counterweight to keep starting resistance manageable instead of feeling glued to the floor.

• Prevents overly heavy or awkward first reps.
• Perfect for high-rep, high-control work where feel matters more than ego.
• Makes advanced strength curves accessible for lifters of all levels.

Compatibility & Safety

• Compatible: Bulletproof ISOLATOR (primary design intent).
• Optional: Jammer arm adapters for most major jammer arm systems.
• Not Intended For: Solo Stand — do not use this product on the Solo Stand.

Set it up on the right platform, follow the install instructions, and you’ll get a tunable, brutally effective resistance tool that still plays nice with your joints.
