What lifters are saying

Verified reviews from the Optimo community

Get More Muscle Activation With Every Lift

Most gym equipment only provide straight cylindrical bars and handles, placing high pressure on a relatively small grip area. This is why we developed Optimo One grips.

A unique anatomical contoured design with palm support prevents imbalances and allows for a more stable and effective grip.

More activation and better reps. By increasing the surface area of the bar, Optimo One grips allow you to focus on lifting heavy, leading to faster upper body gains.

Superior Ergonomics

Equipment compatibility

Will Optimo One fit your equipment?

Inside diameter 28mm / 1.1" — fits standard Olympic barbells and most gym equipment.

If you train with a standard Olympic barbell — they fit perfectly. That covers the vast majority of commercial gyms and home gym setups.

Olympic Barbell

28mm standard

Perfect fit
The standard 28mm Olympic barbell is exactly what Optimo One was designed for. Secure fit, no movement, full ergonomic contact throughout the lift.

Olympic Power Bar

28.5–29mm

Perfect fit
Power bars in the 28.5–29mm range fit securely. The silicone construction accommodates the marginal size difference without any loss of grip stability.

EZ Bar

28–30mm grip section

Perfect fit
EZ bars fit well on the straight grip sections. Position the grips on the flat portions of the bar for full contact and stability.

Smith Machine Bar

28–32mm

Fits most
Most Smith machine bars fall in the 28–32mm range and fit well. Bars at the higher end of that range will have a slightly looser fit but remain secure during pressing movements.

Women's Olympic Bar

25mm

Won't fit
At 25mm the women's Olympic bar is too narrow for the grip to seat securely. Using Optimo One on a 25mm bar is not recommended as the grip may shift during a lift.

Standard 1" Bar

25mm

Won't fit
Standard 1" bars are 25mm with a threaded weight sleeve — too thin for a secure fit. These are typical of entry-level home weight sets. Upgrading to an Olympic bar makes Optimo One compatible.

Fixed Hex Dumbbells

28–32mm handle

Perfect fit
Standard commercial hex dumbbells typically have 28–30mm handles. Optimo One seats securely and delivers the full ergonomic benefit on all dumbbell pressing and curling movements.

PowerBlock Dumbbells

Square frame, 4-point handle

Perfect fit
Optimo One fits PowerBlock handles better than the Pro due to its smaller 1.6" diameter. The PowerBlock's square frame and narrower grip section seat cleanly with the One where the Pro's larger diameter can make positioning awkward.

Adjustable Dumbbells

Bowflex, Nuobell, most systems

Fits most
Most adjustable dumbbell systems including Bowflex and Nuobell have handles in the 28–32mm range. Verify your specific handle diameter before use. The grip zone length on some adjustable systems may be shorter than a standard dumbbell.

Rubber Coated Dumbbells

28–34mm

Fits most
Rubber coated dumbbell handles vary by manufacturer. Most commercial sets fit well. If the handle diameter is at the higher end of 32–34mm the grip will be slightly looser but functional for most movements.

Cable Attachments

Straight bar, lat bar, rope

Fits most
Most straight bar and lat bar cable attachments have handles in the 25–32mm range. Straight bar attachments at 28mm fit perfectly. Rope attachments are not compatible. Verify handle diameter on your specific attachment.

Plate Loaded Machines

28–32mm handle

Fits most
Plate loaded pressing and curling machines typically use handles in the 28–32mm range. Most commercial machines fit well. Machines with fixed curved handles are not compatible.

Curved or Fixed Handles

Non-straight grip section

Won't fit
Optimo One requires a straight cylindrical grip section to seat correctly. Equipment with curved, angled, or fixed non-cylindrical handles will not allow the grip to seat flush and should not be used.

Frequently Asked Questions

Quick distinctions:

  • Ergonomic design: Designed to fit your palm vs uniform cylinder
  • Diameter: 1.6" vs typically 2–2.25" cylindrical
  • Load efficiency: Less forced weight reduction with Optimo One
  • Grip stability: Bar locked in hand vs potential roll with standard fat grips

Standard fat grips increase bar diameter to deliver forearm and grip activation. However, the uniform cylinder does not account for hand anatomy or load distribution, which forces a significant weight reduction and introduces wrist torque under load. The stimulus is present, but the trade-offs are increased grip fatigue and a less consistent training effect, particularly on pressing movements.

Optimo One applies the same thick-grip principle but incorporates an anatomical contoured ergonomic design. At 1.6 inches in diameter, it increases forearm engagement while guiding the wrist into neutral alignment and redistributing pressure evenly across the palm. This reduces bar roll and allows heavier weights to be used for longer periods, producing meaningful muscle irradiation including activation of biceps, forearms, and supporting upper body muscles without compromising pressing technique.

The result is consistent mechanical engagement across every set. Optimo One delivers meaningful neuromuscular activation while eliminating the trade-offs of standard cylindrical grips, making it an efficient tool for lifters who want hypertrophy and grip development without interrupting training quality.

Optimo One improves grip ergonomics and form, increasing muscle activation across every pressing and curling movement.

Optimo Pro has a larger diameter, specifically designed to boost arm development. The thicker grip increases forearm and bicep activation, allowing greater muscle recruitment and faster results with fewer reps.

Lifting straps only solve the grip problem by connecting the bar to your hand. They don’t fix the bigger issue: a standard round bar isn’t anatomically aligned with your palm under heavy load. Optimo grips fill the natural voids in your hand, promoting proper alignment and even pressure distribution. This reduces strain caused by your hand fighting the shape of the bar.

Because Optimo reconfigures how your hand interacts with the bar, it may feel different for the first 1–2 sessions. Most lifters find their "sweet spot" within three workouts as their grip adapts to the anatomical alignment.

Measure from the base of your palm to the tip of your middle finger; if your hand is under 7.5 inches, Optimo One is the better fit, and if it’s over 7.5 inches, Optimo Pro will feel more comfortable and effective.

Compatible with all standard 28-30mm Olympic barbells, EZ curl bars, hex bars, Smith machine bars, plate loaded machine handles, cable attachment handles, and most adjustable dumbbell systems including Bowflex and NuoBell. Works as ergonomic hand grips for barbell and dumbbell training across all upper body movements. Not recommended for pulling movements such as deadlifts, rows, or pull-ups.

Optimo Grips allows for a more natural wrist position and reduces the ulnar deviation often caused by standard grips. While many users incorporate Optimo into rehab protocols to resume training without aggravating strain, it is not a medical device. Consult a healthcare provider for existing injuries.

Yes, and most people feel the difference on their very first set. Unlike standard fat grips that simply add thickness, the Optimo One's contoured palm support cradles your hand naturally, forcing your forearms, biceps and shoulders to work harder simultaneously. You get the full performance benefits of thick grip training with an ergonomic design built to maximize every rep.
