The Lock-N-Float was engineered specifically for the Bulletproof Isolator to create a modular training platform instead of another universal lever arm. Built around a precision-machined center-loaded Lever Arm, the system allows you to add purpose-built attachments without sacrificing rigidity, biomechanics, or versatility.

Start with the Lock-N-Float Lever Arm, then expand your system with the Leg Pads Add-On, the Curl/Dip Attachment, or both. Every component was designed from the beginning to work together as one integrated Isolator platform rather than a collection of unrelated accessories.

The Lock-N-Float is the modular performance platform built specifically for the Bulletproof Isolator.

Traditional universal lever arms are designed to fit as many systems as possible. That versatility often comes with compromises in geometry, leverage, rigidity, and movement quality. The Lock-N-Float was engineered differently. Because it was designed specifically around the Bulletproof Isolator, we were able to optimize the lever geometry, center loading, attachment interface, and Lock-N-Float mechanism as one integrated system.

Start with the Lock-N-Float Lever Arm, the required foundation of the platform. From there, expand your Bulletproof Isolator with the Leg Pads Add-On, the Curl/Dip Add-On, or both.

Build Your Lock-N-Float Platform

Lock-N-Float Lever Arm — Required Base
The foundation of the system. Designed specifically for the Bulletproof Isolator with curved, center-loaded lever geometry and Lock-N-Float functionality.

Leg Pads Add-On — Optional
Transforms the Lever Arm into an adjustable lower-body training station for leg extensions, leg curls, and additional lower-body movements.

Curl/Dip Add-On — Optional
Transforms the same Lever Arm into an upper-body station for preacher curls, machine-style dips, leverage manipulation, and mechanical drop-set variations.

Add Both
Expand one compact Bulletproof Isolator platform into a highly versatile upper- and lower-body training system.

1. Lock-N-Float Lever Arm — The Foundation

The Lock-N-Float Lever Arm is the heart of the entire platform. Its curved, center-loaded architecture reduces effective leverage distance compared with traditional long universal lever arms, helping reduce unwanted flex and creating a more rigid, controlled feel under load.

Instead of placing resistance far to one side of an extended lever, the Lock-N-Float brings the load closer to the center of the system. This creates more balanced resistance and gives the entire platform a more stable foundation for every attachment that follows.

The signature Lock-N-Float mechanism gives you two distinct training modes:

  • Lock Mode: Keeps the system synchronized for maximum stability, controlled tracking, and rigid movement.
  • Float Mode: Allows controlled independent movement with compatible attachments, increasing stabilization demands and making left-to-right differences easier to feel.

Every Lock-N-Float add-on is designed to mount to this Lever Arm, allowing your Bulletproof Isolator to continue expanding without replacing the core platform.

2. Leg Pads Add-On — Lower-Body Expansion

The Lock-N-Float Leg Pads transform the Lever Arm into a purpose-built lower-body station for the Bulletproof Isolator.

The telescoping pad system can be adjusted for different users, exercises, and body positions while supporting movements including seated leg extensions, seated leg curls, prone leg curls, and additional lower-body variations.

Use the Leg Pads in Lock Mode when you want both sides moving together through a stable, synchronized path. Switch to Float Mode to allow independent movement and expose differences in strength, coordination, or movement quality between your left and right sides.

Because the Leg Pads operate from the same center-loaded Lever Arm, you retain the rigidity, balanced resistance, and compact footprint of the Lock-N-Float Platform.

Leg Pads are an optional add-on and require the Lock-N-Float Lever Arm.

*Leg pads use original Isolator pad material.

3. Curl/Dip Add-On — Upper-Body Expansion

The Curl/Dip Add-On transforms the same Lock-N-Float Lever Arm into an adjustable upper-body station for preacher curls and machine-style dips.

Three adjustable width positions allow you to move between narrow, medium, and wide configurations. These changes do more than alter comfort — they change leverage, elbow positioning, peak contraction, and the overall feel of the movement.

Dedicated knurled curl handles provide a secure grip during curl variations, while removable knurled dip bars allow you to quickly convert the platform for machine-style dips without adding another dedicated machine to your gym.

Because you're working with a lever system, changing hand position also changes mechanical advantage. Shorter positioning generally increases felt load, while longer positioning gives you additional mechanical advantage. That makes the system especially useful for leverage manipulation and mechanical drop sets without necessarily changing the weight.

The Curl/Dip Add-On is also compatible with Bulletproof T Flat Palm Grips and can be paired with the Adjustable Weight Arm for additional positioning and counterweight options.

The Curl/Dip Add-On is optional and requires the Lock-N-Float Lever Arm.

One Bulletproof Isolator. A Growing Training Platform.

The Lock-N-Float was designed so adding a new movement doesn't mean adding another full-size machine.

Start with the Lever Arm. Add the Leg Pads when you want dedicated lower-body training. Add the Curl/Dip Add-On when you want more upper-body options. Combine both when you want maximum versatility.

As the Lock-N-Float platform expands, your Bulletproof Isolator can continue gaining new capabilities while using the same core Lever Arm you've already invested in.

One Lever Arm. Multiple training systems. Built specifically for the Bulletproof Isolator.

Why It's Better

Traditional universal lever arms and dedicated machines solve opposite problems.

Universal lever arms try to perform dozens of exercises with one oversized attachment, but that can introduce excessive lever length, flex, awkward loading, and compromised movement quality.

Dedicated machines are purpose-built for specific exercises, but they consume floor space and require a separate investment for every new movement.

The Lock-N-Float Platform was designed to bridge that gap.

By starting with one precision-engineered Lever Arm made specifically for the Bulletproof Isolator, then adding purpose-built attachments, the platform delivers dedicated-machine thinking without requiring a dedicated machine for every exercise.

Why the Lock-N-Float Platform Is Different
Designed for the Bulletproof Isolator The Lock-N-Float doesn't need to compromise its geometry to fit dozens of unrelated rack or lever-arm systems. It was engineered around the Bulletproof Isolator from the beginning.
A Better Lever Arm Foundation The curved center-loaded architecture reduces unnecessary lever distance and helps create a more rigid, balanced platform under load.
Purpose-Built Lower-Body Training Add the Leg Pads when you want leg extensions, leg curls, and Lock-N-Float lower-body training without buying a separate dedicated machine.
Purpose-Built Upper-Body Training Add the Curl/Dip attachment when you want preacher curls, machine-style dips, adjustable widths, and leverage manipulation.
Buy Only What You Need Start with the Lever Arm and select the attachments that matter to your training. Add more later instead of paying for components you don't need today.
One Growing Platform New compatible attachments can expand what your Bulletproof Isolator can do while continuing to use the same Lock-N-Float Lever Arm foundation.
The goal isn't to make one attachment that does everything. It's to build one foundation that can keep becoming more capable.

Biomechanics

Because the Lock-N-Float was engineered specifically for the Bulletproof Isolator instead of being designed as a universal lever arm, the geometry of the system could be optimized around the Isolator's mounting position, movement path, and modular attachment architecture.

Lock-N-Float Lever Arm Biomechanics
Shorter Effective Lever Distance The curved Lever Arm brings resistance closer to the center of the system compared with long traditional universal lever arms, helping reduce leverage-induced flex.
Center-Point Loading Centering the load helps create more balanced resistance and reduces the tendency for one side of the system to dominate under load.
Greater Rigidity Reducing unnecessary lever length and unwanted flex creates a more stable platform for transferring force into the movement.
Lock-N-Float Control Lock Mode prioritizes stability and synchronized movement. Float Mode introduces controlled independent movement when compatible attachments are installed.
Leg Pad Biomechanics
Balanced Lower-Body Resistance The center-loaded Lever Arm helps keep resistance more evenly distributed during leg extensions and curls.
Controlled Tracking Lock Mode allows both sides of the pad system to move together for stable, repeatable movement.
Independent Movement Feedback Float Mode allows the pads to respond independently, making differences between the left and right sides easier to identify.
Greater Stabilization Demand Allowing controlled independent movement requires the user to actively control each side instead of relying entirely on the machine to synchronize the movement.
Curl/Dip Biomechanics
Adjustable Width Narrow, medium, and wide positions change hand and elbow position, allowing the movement to be tailored to different users and training goals.
Manipulated Mechanical Advantage Changing handle position changes the effective lever length and therefore changes felt resistance.
Mechanical Drop Sets Users can manipulate leverage or width to change difficulty without necessarily changing the weight.
Stable Isolator Foundation Both curl and dip movements benefit from the same rigid, center-loaded Lever Arm designed specifically around the Bulletproof Isolator.
Compatibility
The Lock-N-Float Platform was engineered specifically for the Bulletproof Isolator. It is not intended to be a universal lever-arm system.
Bulletproof Isolator Compatibility

Every major component of the Lock-N-Float Platform was designed around the mounting architecture and movement capabilities of the Bulletproof Isolator.

Designing the system specifically for the Bulletproof Isolator allowed the Lever Arm geometry, center loading, Lock-N-Float mechanism, and modular attachments to function together as one integrated platform rather than adapting a generic lever arm to multiple unrelated systems.

Product FAQs
What is the Lock-N-Float Platform?

The Lock-N-Float is a modular training platform engineered specifically for the Bulletproof Isolator. The Lock-N-Float Lever Arm serves as the required foundation, while optional attachments such as the Leg Pads and Curl/Dip Add-On expand the system into different upper- and lower-body training configurations.

Was the Lock-N-Float designed specifically for the Bulletproof Isolator?

Yes. The Lock-N-Float Platform was engineered specifically around the Bulletproof Isolator rather than being designed as a universal lever arm. This allowed the mounting architecture, lever geometry, center loading, Lock-N-Float mechanism, and attachments to be designed to function together as one integrated system.

Why didn't you make the Lock-N-Float universal?

Universal lever arms have to accommodate many different mounting positions, geometries, and equipment designs. By engineering the Lock-N-Float specifically for the Bulletproof Isolator, we were able to focus on rigidity, leverage, loading position, movement quality, and modularity without designing around unrelated systems.

What do I need to purchase first?

The Lock-N-Float Lever Arm is the required base of the system. From there you can add the Leg Pads, the Curl/Dip Add-On, or both.

Can I purchase only the Lever Arm?

Yes. You can start with the Lock-N-Float Lever Arm and add compatible attachments later as your training needs change.

Can I add the Leg Pads later?

Yes. The Leg Pads are a modular add-on that mounts to the Lock-N-Float Lever Arm. You do not need to purchase them at the same time as the base Lever Arm.

Can I add the Curl/Dip attachment later?

Yes. The Curl/Dip Add-On can be added to your Lock-N-Float Platform later as long as you already have the required Lock-N-Float Lever Arm and Bulletproof Isolator.

Can I own both the Leg Pads and Curl/Dip Add-On?

Yes. That is one of the main advantages of the Lock-N-Float Platform. Both add-ons use the same Lever Arm foundation, allowing one Bulletproof Isolator setup to expand into both lower-body and upper-body training.

Are the Leg Pads included with the Lever Arm?

No. The Leg Pads are an optional add-on. They transform the Lock-N-Float Lever Arm into an adjustable leg extension and leg curl system.

Is the Curl/Dip Add-On included with the Lever Arm?

No. The Curl/Dip attachment is an optional add-on that expands the Lock-N-Float Platform into preacher curls and machine-style dips.

What exercises can I perform with the Leg Pads?

The Leg Pads can be configured for movements including seated leg extensions, seated leg curls, prone leg curls, and additional lower-body variations depending on your setup.

What exercises can I perform with the Curl/Dip Add-On?

The Curl/Dip Add-On is designed primarily for preacher curls and machine-style dips. Its three width positions and adjustable leverage also allow you to manipulate movement feel and use mechanical drop-set techniques.

What is the difference between Lock Mode and Float Mode?

Lock Mode keeps compatible parts of the system synchronized for maximum stability and controlled tracking. Float Mode allows controlled independent movement, increasing stabilization demands and making differences between the left and right sides easier to feel.

Why does the Lever Arm use a curved, center-loaded design?

The curved design reduces the effective lever distance compared with traditional long lever arms, while the center-loaded architecture helps distribute resistance more evenly. The goal is a more rigid, balanced, and controlled training platform.

Why does changing the Curl/Dip handle position change the resistance?

Because the attachment operates through a lever, changing hand position changes mechanical advantage. Shorter positioning generally increases felt resistance, while longer positioning provides greater mechanical advantage.

Can the Leg Pads or Curl/Dip Add-On be used without the Lock-N-Float Lever Arm?

No. Both are modular attachments designed specifically to operate with the Lock-N-Float Lever Arm and Bulletproof Isolator.

Will the Lock-N-Float Platform support additional attachments?

The Lock-N-Float was designed as an expandable platform. The Lever Arm provides a common foundation that can support compatible modular attachments as the system continues to develop.
