Overall rating: 4.5 / 5 from 299 reviews.
I would suggest though an improvement, from my experience with fitness tools with springs (whenever it is added another or harder spring, the increase of effort it is done with 50% or 100% which could be harmfull or stressful to use it), to be added springs with 2,5 LBS, 5 LBS, 7,5 LBS, 10 LBS. I would happilly buy such springs 2,5 LBS, 5 LBS, 7,5 LBS, 10 LBS.
Store owner replied: Thank you for your suggestion. We are looking into additional spring tensions.
Great calf machine, sturdy and well done equipment! Happy to have it!
Calf Buster V2 - Calf Extension Machine for Calf Growth, Strength, Rehab, Ankle Strength
I have paralysis in my left calf from a spinal fusion and I cannot do standing calf raises anymore. I just start using the calf buster two weeks ago and I could tell my weak calf is starting to strengthen .
Calf Buster V2 - Calf Extension Machine for Calf Growth, Strength, Rehab, Ankle Strength
As a mechanic I am not afraid to make what works ok, work great. Out of the box this thing works great! Great stretch on my calf and full range of motion. Its not on a set travel path so its just like doing a standing calf raise...at home! Without a huge machine! Trust me! Worth every penny!
Calf Buster V2 - Calf Extension Machine for Calf Growth, Strength, Rehab, Ankle Strength
Great stretch. I use it with shoes to prevent slipping.
Initially I wanted to use at desk to stay active, after gaining a lot of strength felt tapped out on gains until I started using it while holding onto a barbell for stability. Glad I got the extra 40 lbs because initially felt impossible but finally reached them. Took a while to receive but I understand it is a small business and when I reached out it was sent quickly. Interesting design, happy with the purchase as home calf exercises have always been limited by balance.
Calf Buster V2 - Calf Extension Machine for Calf Growth, Strength, Rehab, Ankle Strength
If you have been on Facebook or Instagram lately, you probably notice fitness gadgets are popping up like gangbusters quicker than your local Starbucks. However, there is one product the "Calf Buster" that lives up to its name. If you're suffering from a condition called (SCS) Small Calf Syndrome, the Calf Buster is a small machine roughly the size of a smaller slant board designed to help tone and increase the size if your calfs. Giving my honest opinion, and before I dive into a full review with some tip, this device is solid and extremely well made. Definitely does not feel cheap and you can 100% feel it working. Give it a few months with regular use and SCS won't set in. So, what is this really? It's like the twilight zone, except, instead of sight or sound, it's the midway point of your sit down or standing calf raise machines. The device uses springs to produce force, and can go as low as 40lb of pressure, to as high as 200lbs. By default, it comes with 40 to 180lbs; extra springs can be purchased. If you can do all 180 lbs. or 81 kilograms with ease, you're either an IFBB pro, or you came in contact with gama radiation and are now the incredible hulk, because even 80 lbs of pressure can be challenging; don't worry about out growing it. So how does it work? There are two options. First, you can place your heel on the platform and your foot on the resting pad, or think of it like a car gas pedal and slowly press down. Again, the springs produce the force or tension while leaning over and grabbing a handle for stability, not heavy block weights. Your second option, the included back strap, so you don't have to lean over, and useful very for when the tension is pretty high. Both options are great actually. There is a secondary benefit too. The peddle is designed to be unsteady, meaning it's has small springs inside to tilt left or right. This is great if you have ankle issues and need to strengthen them. Think of going to physical therapy and they give you a small green resistance band. They tell you keep your leg out straight and use the band on your ankle and slowly twisting left and right at physical. The difference is no band and basically same movement to help strengthen your ankle. Calf Buster includes a nice reference workout card to help you meet your gains. Unlike your regular machines, you'll want to do higher reps of say 40 to 50 and sets 4 to 5 according to the card. 1) Have the unit out so you're at a 45 degree angle when seated. 2) When pressing down, keep your heel steady on the platform and foot on the pedal. 3) Think time under tention. You don't want to be pressing down like you just took too many scoopes of pre-workout. Slow and controlled just like any workout you would do. Setup: It's actually really easy but can be confusing at first. 1) Remove the 2 pins and gently lift up on the handle. Now put the pins back in. If you have trouble putting the pins in,, again, it's solid and not cheap just give it a very gentle tap with a rubber mallet. 2) Add more springs if desired but I would start with the default and get use to it at first. The springs simply loop over and pull up to attach into the notches very easily. The 40 lbs springs if you can go that high little muscle is needed. They are not cheap springs. 3)Back rest or pad. It's designed to go higher up on your back not lower so if you're a little shorter and say I can't make the straps and shorter don't worry bring it higher like intended and works perfectly. 4) They don't tell you, the clip or hooks on the back support go on the top handle where the springs go not the bottom area. The manufacturer is very good a responding so any questions just message or email.

As an advid mountain biker, calf and foot strength and stability is critical for proper pedal cadence and bike control. The Calf Buster provides a superior calf workout.

This little gadget are better than most machines in the gym. Its so easy to use but gives so much back. Easy to change weights and the wider straps are perfect
Calf Buster V2 - Calf Extension Machine for Calf Growth, Strength, Rehab, Ankle Strength
I’ve been lifting at the gym for 25 years and my calves have never felt this good. This little contraption allows you to hit them at a different angle than you ever have before - and doing it during a zoom or while watching TV - I have gotten the best results with it not flat on the floor , but in a reclining position where its angled up , I like the deeper stretch. Great product , buy one, get the extra resistance

Was excited to get my Calf Buster this week. Used it to cap off my leg day session and it feels really great- does an amazing job isolating my calves and letting me work up a burn very quickly. There’s. I margin of error- it works exactly the way you’d expect it to and I’ve recommended it to friends and family.

I was worried it would hit the front of my calves too much, but it doesn’t at all! Totally isolates my calves and ensures a full stretch so there’s no cheating. It’s a great product, and perfect for people who don’t have to room or the money for a large machine.
Calf Buster V2 - Calf Extension Machine for Calf Growth, Strength, Rehab, Ankle Strength
Awesome little contraption - was in search for a full-sized calf raise machine until I stumbled upon this. Love that I could train my calves (progressively overload) without taking up a bunch of space.
Calf Buster V2 - Calf Extension Machine for Calf Growth, Strength, Rehab, Ankle Strength
I honestly believe this is the greatest at home/anywhere calf work out machine. It doesn’t get any better than the Calf Buster!
This is a great product! There are not many calf exercise machines in gyms these days, let alone portable and compact options. I was glad to be able to use this. It's lightweight but still provides a maximum calf workout with a lot of range. Its very easy to use and there's no risk of injury with the spring resistance setup. Glad I can end my search for a calf workout!
I've been following the 4 day a week Calf Buster training plan for several months now. Once I learned to use the strap correctly, I got the hang of it right away. My calves have never felt stronger. If you want to feel like you're finally make progress with calves then give Calf Buster a go.
By far the best seated calf workout I've ever experienced.
I’m not one to typically leave reviews on products but the Calf Buster more than deserves one! As a mat Pilates instructor this is a game changer for improving calf strength and general leg mobility! Using it in the classic Pilates position with the pelvis in neutral eliminates the need for the support strap provided. I 12/10 recommend this product. I’ve had nothing but a positive experience, from an extremely responsive customer service team down to minor details like clean and neat packaging.
just started using and I can feel the soreness in my calves way more than when doing typical calf raises. Looking fwd to seeing 2 months of results.
The calf is hard to develop, especially training at home. The Calf Buster works very well and fills an important need for the home trainer. It is well designed and affordable.
I bought the unit to build my calf muscles after lengthy disability (about 2years) due to nerve damage in both legs. I was not doing much training up until about month ago. I got 0.5”-0.6” growth in each leg after about 8-10 sessions of 4x25 on ea leg. Thank you for this device!
I have been using this calf machine everyday for 20 minutes at the end of my home gym workout, since the date it arrived on 10/06/2023(The current date is 10/19/2023). From a functionality and performance perspective, this portable calf machine hits the calves exactly in the way the sitting down calf machine does, in developing the the size, fullness and ripped appearance of the calves, when viewed from directly behind, as well as the diamond shape stemming down towards the ankle(when viewed from the front). I am able to achieve a little over 1/2" increase is calve size when fully pumped, from the 20 minute workout with this calf machine. Using the Belt support, allows me to actually not even have to hold the calf machine handle, to vary the different dynamic feel of using this machine. When I want to add additional dynamic feel to vary the angle, I place a slant wedge under the calf machine. There is no slipping and sliding, this calf machine product stays in place on the ground and on top of my slanted wedge which I prefer to use, for the perfect feel(which is personal and will be different for everyone). From a visual and quality perspective, this calf machine is absolute top of the line durable, solid, and designed with top-notch quality, and thought in regards to the joints, material, color and design and weight. Super light to travel and take with you anywhere and folds even smaller if/when needed. Super sturdy and solid, and the springs are clearly exact if not more sturdy in resistance then what they indicate. I had initially had trouble doing 5 reps with my left calve with just the two default springs, and after 5 days I was able to somewhat work with the next set of springs. I don't plan of being able to move past the current setup of springs I am using, for at least a couple of weeks is my expectation. At the end of the day, all I can say, is that there is no other product like this, a product which actually is a full blown calf machine, in a solid, durable, top quality, weight adjustable, super light weight portable, practical and precise in performance/ functionality. This calf machine gets the job done in the same manner as a full blown seated calf machine and/or stand up calf machine. This product will last me many many years, for it seems to be bullet proof, and has no weak spots or caveats which could cause breakage or cracks etc, so I am very pleased, and give this item a full Two thumbs up!! It is worth every penny and more!! You will get the results you are looking for!!
Calf buster is a game changer, not only do I get the luxury of hitting my calves when and what time I iwant, I also get the benefit of the resistance to give my calves a good workout This machine was worth the wait, and time..
To get started I injured my knees playing basketball. I noticed my knees hurt when I am in the motion of driving(pressing on the gas/ brake pedals). I saw an ad of the calf buster & thought in my head that that seems like a great apparatus for rehab/ prehab for me knee injuries! So I ordered it & been doing it everyday. Lightweight more controlled reps slowly but surely. I feel my knees getting better day by day's. After my knees heal to 100% I will add more resistance to really feel the burn to workout my calves, tibs, ankles, knees & every part the calf buster hits! Great purchase I highly recommend!
Calf buster has been a game changer for me, I struggled in the past with developing calf strength but this calf buster helped me gain the strength and also tone my calves at the same time it is user friendly and a easy, quick effective way to train your calves anywhere anytime.
This machine is amazing. Gives you a great workout. My chicken legs have been taking a beating since I got the Calf Buster.
Great piece of equipment! I've been using my for 6 weeks and I've noticable added some good mass. It's easy to use and the customer support is also great!
As someone who struggles with increasing calf strength, this product has been a game changer for me! I’ve always maintained a moderate level of calf strength and after researching the science behind the Calf Buster, I decided to give it a try and definitely don’t regret it! Highly recommend for anyone looking to improve calf strength - can keep this at my home gym or bring to my office to get reps in during the day.
This thing is awesome!! Saw an ad for this online and debated for a while if I should give it a try. Best decision I could've made. It's simple but also super effective. I like to run a lot in my free time, but on off days I love strength training with calf buster. 10/10 would recommend.
Amazing gym addition! I’ve been wanting a calf machine for my at home gym but have never been able to pull the trigger due to price. The Calf Buster is affordable, fits in any space, and actually works my calf muscles better than a traditional machine. 10/10 product for your gym!
I love the calf buster! My work gets busy thought out the day, but it’s nice to break it up with some type of exercise, which is why I love the calf buster. I lean it against my desk and just grab it when I need a break and want to bust out some calf raises! You can take it anywhere. Highly recommend this product!
This calf machine has improved my life so much. I've had chicken legs growing up and I finally pulled the plug to change for the better. It's super lightweight and perfect to use on my work break. I wore shorts for the first time of the summer and my best friend was in disbelief. Can't wait to continue my calf journey and have the sexiest legs around. Whoever designed this, you're a genius.
This was a great addition to my workplace! I need ways to stay active during the workday, and ever since i've been working out my calves with the Calf Buster, I can walk for a longer period of time without feeling tightness. calves. I have gained strength and also seen some lengthening. Great product! 10/10 recommend.
It works good.
Awesome product 100%
