Hand grip trainers are one of those accessories that seem simple until you actually start using them regularly. The New Millennium Grip Strength Trainer 4-Pack aims to cover the basics with a set of foam-covered exercisers, each with a different resistance level. After spending a few weeks rotating through them during work breaks and evening downtime, I have a clear picture of what they do well and where they fall short.
The set includes four units, typically color-coded by resistance—light, medium, heavy, and extra heavy. The foam wrapping is soft to the touch and provides a more comfortable grip than the bare metal or plastic you find on many budget trainers. That foam also makes them less likely to slip out of your hand when your palms get sweaty, which is a practical plus if you’re using them at a desk or while watching TV.
Using them is straightforward: you squeeze, hold, and release. There’s no spring-loaded mechanism that snaps back aggressively, which is actually a benefit if you have joint concerns or are just starting out. The resistance comes from the internal spring, but the foam absorbs some of the initial shock, making the motion feel smoother than on a typical metal gripper. For rehabilitation purposes—say, after a minor hand strain—the lighter two levels are gentle enough for slow, controlled reps. The heavier ones give a decent workout for building basic grip strength, though they’re not going to replace a dedicated grip crusher for serious lifters.
One thing I noticed is that the foam does compress over time. After a couple of weeks of consistent use, the lightest unit started to feel a bit softer, and the foam on the heavy one showed slight indentations where my fingers pressed. It’s not a dealbreaker, but it does mean the resistance levels aren’t perfectly consistent forever. If you’re someone who tracks progress precisely, you might find that annoying. Also, the foam can pick up dirt and sweat, and while it’s wipeable, it’s not machine washable. You’ll want to keep them dry and clean them occasionally with a damp cloth.
Compared to a solid metal grip trainer like the Captains of Crush or a variable-resistance device like a grip ball, these are more approachable and less intimidating. They’re also cheaper, which makes them a good entry point if you’re not sure how much you’ll actually use a hand exerciser. But that lower price comes with a trade-off: they don’t offer the same precision or durability. A metal gripper with adjustable tension will last longer and give you a more progressive overload path, but it’s also harsher on the hands and costs more. For most casual users, the New Millennium pack is a friendlier option.
Who are these for? Office workers who want to relieve hand stiffness from typing, musicians looking to build finger endurance, or older adults doing light hand therapy. They’re also fine for someone new to grip training who doesn’t want to invest heavily. On the other hand, if you’re a climber, powerlifter, or someone who already trains grip seriously, you’ll likely outgrow these quickly. The resistance caps out at a level that’s challenging for an average person but not for someone with trained hands.
Another limitation is that the 4-pack doesn’t come with any guidance or workout plan. You’re left to figure out reps, sets, and frequency on your own. That’s fine for experienced folks, but beginners might not know how to structure a session. A small pamphlet would have been a nice addition, but its absence isn’t a fatal flaw—there are plenty of free routines online.
In terms of build quality, the springs feel solid for the price, and the foam is stitched securely around the core. I didn’t notice any fraying or loose ends during my testing. The different colors make it easy to grab the right resistance without looking, which is a small but thoughtful touch. The set comes in a simple plastic bag, so don’t expect premium packaging—it’s a utilitarian product through and through.
One more thing worth mentioning: the foam tends to retain odor if you use them heavily and then toss them in a gym bag. I’d recommend letting them air out after a workout. It’s a minor maintenance issue, but it’s something to keep in mind if you’re planning to use them daily.
Overall, the New Millennium Grip Strength Trainer 4-Pack is a practical, no-frills option for anyone needing a range of resistances without spending a lot. It’s not a high-end training tool, and it won’t satisfy advanced athletes, but for everyday conditioning, stress relief, or light rehab, it gets the job done. The foam comfort is a real advantage over bare-metal alternatives, and the four levels give you room to progress a bit. Just don’t expect them to last forever or to provide the kind of precise, measurable resistance that serious grip enthusiasts want. If that’s you, look elsewhere. If you just want something to squeeze while you’re reading or on a conference call, this pack is a reasonable choice.
