What Customers Are Saying..

"The Rolls Royce of ankle weights.

This is an exceptionally well made product.

For anyone who uses ankle weights in their workout routine you will be pleased with these.

If you are looking for ankle weights that you can adjust to almost any weight you want then this is it.

The only thing you can't do is run in them but you can do just about everything else.

It is very well made, so you do get what you pay for, but it is an investment.

Hopefully one that you will get many years of use out of.

"Way better than monkey feet

Easy to put on and add weights unlike monkey feet which were too hard to strap in.

I have large feet and ankles which made it an absolute chore trying to fasten monkey feet.

ANKRs are way easier to strap on even with the weights on.

The list are set much high yet than on the bottom making it way easier to actually move and walk with them on.

Great construction and quality materials. Very happy with these ANKRs!!"

A New Study: Squats vs Leg Extension
(For Quad Growth)

Zabaleta-Korta (2021), The role of exercise selection in regional Muscle Hypertrophy: A randomized controlled trial, J Sports Sci.

The quadriceps is one of the biggest muscles in your body. It is one of your most important muscles in sports, and you cannot build a strong and impressive physique without them.

In a new 2021 study, 21 young men with strength training experience trained their respective exercise three times per week, doing four sets of twelve reps to muscular failure each workout.

Before and after the five weeks of training, the researchers used ultrasound to measure the cross-sectional area of the participants’ rectus femoris and vastus lateralis.

The study showed that the leg extension lead to significant more gains in the quads especially in the Rectus Femoris.

Ordered a pair of EZ-BOOT MAX Sunday recieved them by Thursday. These are great space savers I don't need any machines to give my legs a workout, items came well packaged and quickly just like my EZ-VEST MAX V2 also from Kensui, thank you.

Ankr-Max: Adequate and Versatile

The design of the Ankr-Max is similar to an open ended ankle boot with straps. With accoutrements and a lot of extras, one could perform a decent range of leg exercises bilaterally or unilaterally depending on your price point. I went for the single Ankr-Max with 1 in. plate adaptors and the heel plate adaptor.

A few notes:
I received the two vegan leather ankle pads without any instruction of how to attach them as they are in the website photos. They appear to have a "padded" side and a micro-velcro side, but no means to attach them to the ankle screw-ins. So basically they are just not attached and sitting on the side.

The boot and attachments appear to be made with a high grade plastic, but it's not something I would want to test deliberately or accidentally with dropping or impact for fear of deforming or cracking a component.

While the heel insert is adequately designed, it was a little challenging to secure in the slot and with it inserted, it is very awkward to strap in and then move into an exercise position. You sort of have to keep your foot elevated and swing it around to a secure start point for reps.

The straps are of decent quality with the metal clips, I am concerned about the longevity of their use under load. They are also fairly long and the extra slack tends to just dangle or flop around when performing sets. I understand the strap length is if you wanted to do Tibialis Anterior work at a different foot angle, but the design is a little awkward and unwieldy to get in and out efficiently.

I would like to see if there are resistance band attachments in the future.

Great for so many exercises.

Used as an achor for crunches, used in leg lifts, gluten kicks, leg extensions, leg curls, hip flexers....the list is endless.

Its a good start, looking forward to a improved ANKR MAX Version 2 in the future

I have to use it more delicately as I move up in weights. With enough weights + contact with the ground at a certain angle, you can potentially break it. The threads for my bottom sleeve snapped when loaded at 20kg on the bottom + 7.5kg on each side. I’m just doing hip flexor raises with these (one side at a time, one foot standing on a bench) and right now there are not a lot of options out there that let me use olympic plates as the primary resistance. This device also does a decent job at solving this common issue with weighted feet attachments in that when you load more and more weights the weights itself begins to restrict your range of motion by bumping into things. My only problem is that this thing just needs to be a lot more durable. You’re going get tired during reps and will have to drop this on the ground and I don’t think this thing is well rated for that. Maybe if it was either: less plastic based and more metal (preferably steel) or thicker and possibly longer threads where the sleeve attaches to the ANKR frame. (or more entirely a strap based design with no molded frame, but then this will just fix my personal problem and not address the general populations issue)

Overall, I like this thing. It just needs to be made much tougher.
