Increased Muscle Activation

The Increased Muscle Activation Unlocks Size and Strength Gains

The thicker handles stimulate much more muscle activation in the hands, forearms, upper arms and whole upper body. More muscle activation means much bigger muscle and strength gains because your body can finally stop "holding back".

You Are Only As Strong As Your Weakest Link

Example: if your big bench-pressing muscles (pecs, delts, triceps) can handle 400lbs but your hands and forearms can only handle 200lbs, then your bench press is 200lbs. The biggest weakness almost every lifter and athlete has is in the hands and forearms. Think that's not a problem? Think again. The hands and forearms are your point of contact with the weight in 95% of exercises. Fat Gripz increase muscle activation throughout the entire arm and solve this problem by adding size and strength to the forearms and biceps, fast.

Less Imbalances & Injuries

Thick bars/Fat Gripz shift the stress off the joints and onto the muscles because a thicker handle spreads the weight over a larger area of the hand (just imagine bench pressing with a thicker bar compared to a standard skinny bar). It also makes the forearms extensors (the muscles on the top of the forearm) and forearm flexors (the muscles on the bottom) both work similar amounts and so helps avoids imbalances, weaknesses and injury.

You can easily use them on the EZ Curl Bar, a barbell, or dumbbells.

Fat Gripz have helped me in so many ways imaginable; they increased the muscle and definition gains on my arms while also making my grip strength insanely stronger.
I can honestly tell a huge difference in my forearm strength, less joint pain, and I have noticed it helps focus on the main muscle I am working that day!

I was considering buying a fat bar, but after coming across so many good reviews (and video reviews if you look for them) I decided to give Fat Gripz a try. I haven't used a fat bar before, but I can imagine these are similar enough that you can use them for most of the same lifts. I'm not sure I'd try any olympic lift variations using them. (This concern may just be because my grip strength isn't "quite there" yet.) I have used them for straight leg dead lifts and they stay on pretty comfortably. Additionally, I think they have an advantage vs a fat bar because you can apply them to ANY bar or dumbbell. Fat bars are pretty standard, not lots of variation. These can be slapped onto bars, dumbbells, cable attachments, pull up bars, special bars, etc.
A couple things I was concerned about that I learned after ordering:
-They are VERY heavy duty rubber. I used them on a brand new texas power bar (DEEP knurling) and it did nothing to damage the rubber.
-They attach and detach simply, you need two hands to pull it open and it just clamps on the bar
-They retain their shape very well after removing from the bar (not stretched out)
-Each fat Grip itself is pretty heavy (not so heavy that I would say "I benched 302 pounds counting the fat gripz" but heavier than I expected,) which is good in my opinion.

The only thing I'm not crazy about is that when they are placed on an olympic bar there is ~1 cm gap on the opening side. I'm not sure how/if fat Gripz could fix that, and it really isn't a huge problem. It just takes a little getting used to. I found the positioning of that gap is important and different for a push vs a pull. This is part of the reason I don't think I'd olympic lift in them.

All in all I'm very happy with them and they certainly do humble your grip strength the first time you use them. I look forwards to regularly using them within workouts.

I rarely write reviews. Just selfish I guess but I have to share since I have heard so much about these and have read some negative comments.

#1 The good: I buy a lot on Amazon, I shop for bargains everyday and I like quality over quantity. I always say, "skimp on price you will buy twice". These are tough made, solid construction devices. you get your moneys worth and unless you have a dog with a strong jaw use them as a chew toy, they just may last upwards of ten years. They go on and off easily.

#2 The bad: On two of my bars there is a gap. On one it is barely noticeable on the other it is maybe 1/2 an inch. Here is the secret..ready.... move the darn grip! If you rotate it you can make it face out , in, up, down or against your hand, if you wear gloves this isn't even an issue. So if you want to get these do not let those reviews scare you off. Common sense is available to all.

#3 The ugly: I just did bi's and tri's with these, I had to lower my weight and my forearms are so hurt I am typing veeerrrryyyy slowly. These surpass what I expected and if you are looking to fullfill your workout routine with huge arms and empower your forearms and grip to maximum results use these and when these get "old" get the Extremes. BUT do not think you can do the extremes NOW... these regular one will humble you.

As for the person who posted that these rotate around the bar, etc. If you are using these on a bar that is so thin it rotates around, do yourself a favor... return the bar to the elementary school you got it from and get an adult bar...I can not fathom in what world these will rotate around a bar for an adults gym.

If you are using these for pull ups and there is some rotating...THAT i can understand...

These things are intense. A little pricey, which is why I held off for awhile before buying them, but well worth it. If you're looking for a fantastic and simple (not to say easy) way to increase grip strength and forearm development, these are the ticket. I've only been using them for a week and already I'm feeling results. Beware: if you use them on deadlift or rowing exercises, be prepared to be humbled. Quickly. I didn't really see a big weight or volume reduction when using them on curls (some to be sure) but WOW, when I used them on deadlifts, I couldn't get beyond my warm up weight for sets of six before my forearms were screaming. Even then, I had to reset my grip after every two reps at least. Looking forward to continuing to challenge myself and build Herculean forearms with these. 5 stars.

My results have been OK. But nothing great.
It's nice to have the product just to change things up a bit.
It's a very well made product... very durable.
but reading some of these other reviews, you'd think these things were the second coming of Jesus.
I have to believe there's a large amount of marketing hype here.
I wouldn't go so far as to say there is fraud occurring here, but man, I've got to wonder...
And $37 bucks is a lot of money for these things.
I've been lifting most of my adult life. and let's face it.. there's a lot of snake oil shucksters in the business of bodybuilding.
Having had a chance to use them and see what impact they've had on my arms, I'd doubt I'd buy them again if I lost this pair.
