Optimo Pro Ergonomic Thick Grip Review

About This Review

This page is an Optimo Pro review written by the team that builds it. It is not a third-party review, and we are not going to pretend it is. What it is, instead, is the page we would want to read if we were considering a premium ergonomic thick grip and trying to decide whether it was right for our training.

That means honest evaluation. What the Pro does well. What it does not. Who it is the right tool for, and who should probably buy something else. What the adjustment period actually feels like. What our own customers say about it, including the parts that are less than a rave. If you came here looking for a five-star infomercial, this is not that page. If you came here trying to figure out whether the Optimo Pro fits your training, read on.

What the Optimo Pro Is

The Optimo Pro is an ergonomic thick grip attachment with a 2.25 inch (57mm) outer diameter. It slides onto standard 28mm to 32mm barbells, Olympic bars, EZ bars, dumbbell handles, and cable attachments, converting any of that equipment into a thick bar training surface.

What separates the Pro from other thick grips on the market is the wing-shaped palm support built into the geometry. Rather than a uniform cylinder, the Pro incorporates a contoured shelf that sits against the heel of the palm during pressing and curling movements. That shape distributes load across the full hand rather than concentrating it at a narrow contact band in the center of the palm, which is the limitation of cylindrical thick grips under heavy loads.

The Pro is manufactured from high-density medical-grade silicone. The material choice matters for a specific reason: under extreme loads, cheaper rubber and foam thick grips compress and deform, which changes the ergonomic geometry mid-set. The silicone compound we use maintains its shape under load, so the contact surface you grip at the start of a set is the same contact surface you grip at the end of it. The Pro also features knurling on the outer grip surface for additional traction security under heavy use and high sweat conditions.

What It Feels Like to Use

The first thing most lifters notice when they use the Pro for the first time is that their grip feels different. Not worse, different. A 2.25 inch diameter forces the hand into a more open position than a standard 28mm barbell, and your forearm has to work meaningfully harder to maintain control. This is the point of the product, but it can feel like a limitation in the first session or two if you were expecting immediate comfort without any adjustment.

The second thing lifters notice is the wing. On pressing movements, the contoured surface sits against the heel of the palm and creates a stable shelf for the pressing force to drive through. It is the kind of design detail that is difficult to describe in text but unmistakable the first time you do a set of heavy bench press with it seated correctly. The load distribution across the full palm is the functional benefit, and it is the single most common thing customers mention after their first few training sessions.

The third thing lifters notice is the weight reduction. You will not press as much weight with the Pro as you will with a standard bar. Plan to reduce working weight by roughly 15 to 20 percent on pressing movements and 20 to 25 percent on curling movements when you first add the Pro to your program. This is expected. It reflects the increased demand placed on your forearms and supporting musculature, not a limitation of the product. Over the first four to six weeks of consistent use, the gap closes significantly as your grip and forearm strength develop.

The adjustment period is real and should be planned for. Most lifters need three to five sessions before the Pro feels natural rather than novel. Forearm soreness in the first week is normal and confirms the training effect is working. If you are expecting a plug-and-play experience with no adjustment required, the Pro is not the right tool for you, and we will talk about who it is not for in a section below.

Who the Optimo Pro Is For

The Pro was designed for a specific type of lifter. Being clear about who that is matters more than a generalized "everyone benefits" pitch, because the Pro will actively underperform for the wrong buyer.

Serious lifters focused on arm and forearm development. The Pro's 2.25 inch diameter produces deeper forearm fiber recruitment than standard thick grips, which makes it the right tool for bodybuilders and physique-focused lifters specifically chasing bicep thickness and forearm size. If arm development has plateaued despite consistent training, the Pro is one of the highest-leverage changes you can make to restart growth.

Lifters who train primarily pressing movements. Bench press, overhead press, close grip press, dumbbell press, cable press, and all their variations are where the Pro's ergonomic design delivers the cleanest benefit. The wing supports the palm during pressing, the diameter amplifies forearm activation, and the load distribution makes high-volume pressing sustainable over time.

Lifters specifically targeting grip strength and forearm hypertrophy. Used as a finisher tool at the end of an upper body session for static holds, hammer curls, or preacher curls, the Pro produces the sustained forearm fatigue that drives grip strength and size development faster than standard bar work.

Home gym lifters who want to upgrade their existing equipment. A $159 investment converts every barbell and dumbbell in a home gym into an ergonomic thick bar. For lifters who would otherwise consider buying specialty equipment like axle bars or thick-handle dumbbells, the Pro delivers the same training stimulus at a fraction of the cost without taking up any additional space.

Lifters who have already tried standard cylindrical thick grips and want something better. If you’ve used standard cylindrical thick grips and want a more ergonomic alternative, the Pro addresses the limitations of cylindrical design. The wing-shaped palm support distributes load across the full hand rather than concentrating it at narrow contact points.

Who the Optimo Pro Is Not For

This is the section we think matters most on a page like this. A product that works for everyone usually works for nobody. Here is who should probably buy something else.

Powerlifters peaking for a one-rep max. If your training goal is a peak strength expression on a specific competition lift, the Pro is counterproductive. Grip becomes the limiting factor before the primary movers are fully tested. Your peaking work should stay on a standard bar.

Lifters whose training is primarily pulling-focused. The Pro is designed for pressing and curling movements. If the majority of your training volume is built around heavy pulling work, you will find limited use for the Pro in your main program. You might still benefit from adding it for accessory pressing work, but it should not be your primary equipment investment.

Lifters with very small hand spans. The 2.25 inch diameter is designed to challenge the grip. For lifters with smaller hands, that diameter can cross the line from productive challenge into unmanageable. If you have small hands and are new to thick grip training, the Optimo One at 1.6 inches is a better starting point.

Beginners in their first three months of training. The Pro assumes a baseline of grip strength and connective tissue adaptation that new lifters do not yet have. Introducing thick grip training too early produces forearm soreness that limits training frequency and can discourage consistency. Build foundational strength on standard equipment first.

Lifters who want plug-and-play equipment with no adjustment period. The Pro changes how your lifts feel. The first three to five sessions are an adaptation period. If you are not willing to reduce working weight temporarily and let your forearms adapt, the Pro will feel like a limitation rather than a tool.

Lifters shopping primarily on price. The Pro is a premium product and we do not apologize for that. If budget is the dominant consideration and you want the cheapest thick grip available, there are rubber cylindrical options at a third of the price that will add diameter without the ergonomic architecture. Those products exist and they have their place. The Pro is not built to compete with them on price.

What Lifters Say

The Optimo Pro was developed in direct response to customer demand. The Optimo One, which shares the Pro's wing design and high-density silicone construction at a smaller 1.6 inch diameter, was released in 2019 and has accumulated 114 Amazon reviews at 4.4 stars. The Pro was built because One customers kept asking for a thicker version. The very first review that mattered for the Pro's development was this one, left on the Optimo One Amazon listing before the Pro existed:

"Great product. Waiting for the fat grip version to come out."
Greg, verified Amazon review

The reviews below are from the Optimo One customer base. The One and the Pro share the same ergonomic wing design, the same high-density silicone construction, and the same manufacturing standards. What differs is diameter. We are surfacing these reviews because what customers say about the design, the material, and the feel applies to both products.

"Works well. I was a bit concerned as they are different from other grips I've used but really nice, especially the fin, gives something to get extra grip on."
Bradley Jones, verified Amazon review

"Definitely more comfortable bench and military press. Fits well in my palm."
JH, verified Amazon review

"These work really nicely for pressing movements, particularly with dumbbells. No more dumbbell rolling in your hand or bar digging into the palm, they give a nice surface to press on."
Verified Amazon review

"They go on and off of my hex dumbbells easily. I bought them to help spread out the load on the palms of my hands to make heavy dumbbell pressing more comfortable and they do just that."
Michael Knickerbocker, verified Amazon review

"I've been using this for 4 or 5 weeks and am very happy with it. It does take some getting used to since your grip is different. But once you get a feel for it, I can lift more with it. It hits your chest differently too."
Chuck C, verified Amazon review

"Moved my bench press up 2-3 more reps in the 8-10 range."
Andrew, verified Amazon review

"I had high expectations for them and they did not disappoint. Major upgrade for my gym."
Dylan Tellam, verified Amazon review

We have also received feedback from industry professionals who have tried the product, including world heavyweight champion arm-wrestler Michael "Monster" Todd, who said: "I do my entire chest workout with it. I notice immediately when I grab it, it takes pressure off the joints. Highly recommend these if you're gonna be doing any type of pushing exercises."

Optimo One vs Optimo Pro

If you are deciding between the One and the Pro, this is the section for you. Both models share the same wing-style ergonomic design, the same high-density silicone construction, and the same equipment compatibility. The meaningful difference is diameter and the training stimulus that diameter produces.

The honest framing: if you are new to thick grip training or you want the versatility of a single grip that works across general upper body training, buy the One. If you are specifically targeting forearm hypertrophy, bicep thickness, or grip strength development, buy the Pro. If you are serious enough about training to own both, we sell them both.

For a more detailed breakdown of when to use each, the Complete Guide to Gym Grip Attachments covers the decision in more depth.

Who Makes the Optimo Pro

Optimo Fitness Ergonomics was founded in 2016 by Pierre, a lifter who ran into a problem that standard equipment could not solve. Every thick grip on the market at the time was a cylindrical rubber attachment that added diameter but ignored the anatomy of the hand. Pierre designed the wing-shaped palm support as the missing piece of that category, brought the first ergonomic thick grip to market in 2019 as the Optimo One, and released the Optimo Pro in response to customer demand for a thicker diameter with the same ergonomic architecture.

Optimo's wing design was the first ergonomic thick grip on the market when the One launched in 2019. The Pro inherits and refines that architecture with a larger diameter. The left and right grips are anatomically matched to each hand, which is why we sell them as a pair and mark them for orientation.

We manufacture in limited runs, which is a conscious choice. It lets us hold quality standards that mass production would compromise. It also means we are not the cheapest option in the category, and we are not trying to be.

Tradeoffs and Things to Know

Every product has tradeoffs. Here are the ones worth knowing about the Pro specifically before you buy.

The adjustment period is real. Plan for three to five sessions before the Pro feels natural. Forearm soreness in the first week is normal. If you do not allow for the adaptation period, the Pro will feel like a limitation rather than a tool.

Fit on very narrow dumbbells can be inconsistent. The Pro is designed to fit standard 28mm to 32mm handles. On dumbbells with unusually narrow handles (under 25mm), the grip may not seat tightly and can rotate during use. Thick grip adapters as a category are designed to fit standard 28mm to 32mm handles. On equipment with unusually narrow handles (under 25mm), no thick grip adapter will seat tightly. If your primary equipment is narrow-handle dumbbells, check the handle specification before buying any thick grip.

The Pro is not a substitute for heavy standard bar work. Your heaviest strength expressions should still happen on standard bars. The Pro is an accessory and hypertrophy tool, not a replacement for your primary lifts. Build your program with both in mind.

Some lifters do not get along with ergonomic architecture. A small percentage of lifters prefer the symmetry of pure cylindrical grips and find the directional wing design feels counterintuitive. If you have tried ergonomic equipment before (ergonomic keyboards, ergonomic mice, ergonomic handles) and consistently preferred the non-ergonomic version, you may have the same response to the Pro. This is not a defect. It is a preference.

It is more expensive than cylindrical alternatives. We have said this already but it bears repeating. You can buy cylindrical rubber thick grips for $40 to $60. They work. They are just not the same product. You are paying for the ergonomic architecture, the silicone material, the load-distribution design, and the manufacturing standards. If those things do not matter to you, the Pro is not the right product for you.

How to Decide If It's Right for You

If you have read this far, you are probably close to a decision. Here is a simple framework to make it clear.

The Pro is right for you if: you are a serious lifter focused on arm and forearm development, your training is primarily pressing and curling work, you have tried or considered thick grip training before, you want a tool that will last years rather than months, and you are willing to invest in an adjustment period in exchange for a better long-term training experience.

The Pro is probably not right for you if: you are a powerlifter peaking for competition, your training is mostly pulling-focused, you are in your first few months of lifting, you want the cheapest thick grip available, or you are shopping for a plug-and-play solution with no adjustment period.

If you are still unsure: start with the Optimo One. At 1.6 inches it produces a meaningful training effect with a smaller adjustment period, and it covers a wider range of training contexts. If you want the Pro later, it will still be here. Many of our serious customers own both.
