Grip Training Tools: What Circus Strongmen Use (And What to Avoid)

Quick answer

Circus strongmen rely on a mix of traditional and modern grip training tools to build crushing strength and endurance. The best tools—like thick-handled dumbbells, pinch blocks, and spring-loaded grippers—target specific grip types (crush, pinch, support) without overloading joints. Avoid cheap, flimsy grippers or overly rigid tools that limit natural movement. Start with 2–3 versatile tools, train 2–3 times a week, and progress gradually to avoid injury.

If you want a structured plan that ties these tools together, Unbreakable Hands in 30 Days breaks down exactly how circus performers use these tools for real-world strength.

Why Grip Training Tools Matter for Strongmen

Grip strength isn’t just about holding heavy objects—it’s the foundation of nearly every strongman feat, from bending nails to lifting atlas stones. Circus performers, in particular, need grip that’s both powerful and precise. A weak grip fails under pressure, while an unbalanced grip leads to injuries or uneven development.

Most grip training tools fall into three categories:

• Crush grip tools: Target the fingers and palm (e.g., hand grippers, thick bars).
• Pinch grip tools: Focus on thumb strength (e.g., pinch blocks, plates).
• Support grip tools: Build endurance for holding heavy loads (e.g., farmer’s walk handles, towels).

Using the wrong tool—or using the right tool incorrectly—can stall progress or cause strain. For example, a beginner who jumps straight into heavy spring grippers may develop tendonitis, while someone using only pinch blocks might neglect crush strength entirely.

Traditional vs. Modern Grip Tools: What Circus Strongmen Prefer

Circus strongmen have used the same core tools for over a century, but modern materials and designs have refined them. Here’s how they compare:

Traditional Tools

1. Thick-Handled Dumbbells and Barbells

These are the backbone of grip training. A 2-inch diameter handle forces your fingers and forearms to work harder than a standard bar. Circus performers use them for presses, rows, and deadlifts to build functional strength that translates to real-world feats.

Pros:

• Builds full-hand strength, not just fingers.
• Improves grip endurance for long performances.
• Doubles as a general strength tool.

Cons:

• Expensive compared to other tools.
• Requires access to a gym or specialized equipment.

2. Spring-Loaded Hand Grippers

These are the most recognizable grip tools, but not all are created equal. Circus strongmen avoid cheap plastic grippers (which break or provide inconsistent resistance) and opt for heavy-duty steel models with adjustable tension. The key is progressive overload—starting with a manageable resistance and increasing it over time.

Pros:

• Portable and easy to use anywhere.
• Great for isolating crush grip.
• Adjustable resistance for gradual progression.

Cons:

• Overuse can lead to tendon strain.
• Doesn’t train pinch or support grip.

3. Pinch Blocks

Pinch blocks are simple wooden or metal blocks with smooth surfaces for gripping between the fingers and thumb. Circus performers use them to train for feats like lifting anvils or holding heavy plates. The wider the block, the harder the grip challenge.

Pros:

• Targets thumb strength, which is often neglected.
• Can be made at home with scrap wood.
• Improves dexterity for precision feats.

Cons:

• Limited resistance options for advanced users.
• Can be slippery if not textured properly.

Modern Tools

1. Adjustable Thick Bars

Modern thick bars use removable sleeves to adjust the diameter, making them more versatile than fixed thick-handled dumbbells. Some even have uneven or rotating handles to challenge grip stability. Circus performers use these for dynamic lifts like cleans or snatches.

Pros:

• Customizable diameter for progressive overload.
• Can be used for a variety of lifts.
• More affordable than fixed thick bars.

Cons:

• Sleeves can shift during use, affecting balance.
• Not as durable as solid thick bars.

2. Plate-Loaded Pinch Grippers

These tools replace traditional pinch blocks with a plate-loaded design, allowing for incremental weight increases. They’re ideal for advanced users who need more resistance than a standard block can provide.

Pros:

• Progressive resistance for long-term gains.
• More compact than pinch blocks.
• Can be used for one-arm pinch training.

Cons:

• Expensive compared to DIY pinch blocks.
• Requires weight plates, limiting portability.

3. Farmer’s Walk Handles

Farmer’s walk handles are long bars with handles in the middle, designed for carrying heavy weights over distance. Circus performers use them to build support grip endurance, which is critical for feats like carrying multiple kettlebells or holding a human flag.

Pros:

• Trains grip, core, and full-body stability.
• Mimics real-world strongman feats.
• Can be loaded with heavy weights for advanced training.

Cons:

• Requires space to walk safely.
• Not suitable for beginners without supervision.

What to Avoid: Grip Tools That Waste Time or Cause Injury

Not all grip tools are created equal. Some are ineffective, while others can lead to injuries if used improperly. Here’s what to skip:

1. Cheap Plastic Hand Grippers

These grippers often have weak springs that don’t provide enough resistance or break after a few uses. They’re also poorly designed, leading to uneven pressure on the fingers and joints. If you’re serious about grip training, invest in a high-quality steel gripper with adjustable tension.

2. Overly Rigid Thick Bars

While thick bars are great for grip training, some modern versions are too rigid, limiting natural hand movement. This can lead to wrist strain or uneven muscle development. Look for thick bars with a slight flex or textured surface to improve grip without sacrificing safety.

3. Grip Machines with Fixed Paths

Some gyms have grip machines that force your hand into a fixed movement pattern. These machines don’t mimic real-world grip challenges and can lead to imbalances. Stick to free weights and tools that allow natural movement.

4. Finger Extensors (Without Balanced Training)

Finger extensor bands are marketed as a way to prevent imbalances, but they’re often overused. If you’re not also training your flexors (the muscles that close your hand), you risk creating muscle imbalances that lead to injury. Use extensors sparingly, if at all.

How to Choose the Right Grip Tools for Your Goals

Common Grip Training Mistakes (And How to Fix Them)

Even with the right tools, it’s easy to make mistakes that slow progress or lead to injury. Here’s what to watch out for:

1. Overtraining the Crush Grip

Many beginners focus solely on crush grip (e.g., hand grippers) and neglect pinch and support grip. This leads to imbalances and weaker overall grip strength. Fix it by dedicating at least one session per week to pinch and support grip training.

2. Ignoring Recovery

Grip training taxes the tendons and forearms, which recover more slowly than muscles. Overtraining can lead to tendonitis or chronic pain. Fix it by limiting grip training to 3–4 times per week and incorporating rest days or active recovery (e.g., light stretching, mobility work).

3. Using Too Much Weight Too Soon

Jumping into heavy weights before mastering form can lead to injuries or stalled progress. Fix it by starting with lighter weights and focusing on controlled movements. Gradually increase resistance as your grip strength improves.

4. Neglecting Grip-Specific Warm-Ups

Cold hands and forearms are more prone to injury. Fix it by warming up with light grip exercises (e.g., squeezing a stress ball, wrist circles) before heavy training.

5. Inconsistent Training

Grip strength fades quickly without regular training. Fix it by scheduling grip sessions at least twice a week and tracking progress with a training log.

If you’ve hit a plateau or are struggling with injuries, Unbreakable Hands in 30 Days includes troubleshooting guides and recovery protocols to help you train smarter, not harder.

Final Tips for Maximizing Your Grip Training

Before you start, here are a few practical tips to get the most out of your grip training:

• Train Grip at the End of Workouts: If you train grip at the start of a session, your hands will fatigue quickly, limiting your performance on other lifts. Save grip work for the end of your workout.
• Use Chalk Sparingly: While chalk improves grip, overusing it can mask weaknesses. Train without chalk occasionally to identify and address grip limitations.
• Incorporate Dynamic Movements: Static holds (e.g., dead hangs) are great, but dynamic movements (e.g., cleans, snatches) build functional grip strength that translates to real-world feats.
• Listen to Your Body: Grip training should challenge you, not cause pain. If you feel sharp pain in your joints or tendons, stop immediately and reassess your form or resistance level.

If you’re ready to take your grip training to the next level, Unbreakable Hands in 30 Days gives you the exact system circus strongmen use to build unbreakable grip strength—safely and efficiently.
