Was skeptical about buying this at first. Wasn’t sure if I really needed it or if it would just collect dust on a shelf. Have to say I absolutely love it! Able to target muscle groups in a way that bands and other devices don’t allow. Would definitely recommend!
Works exactly how I thought it would. If you’re willing to use it correctly and often you will get the results you want.
Great versatile piece of equipment. Can easily go from working the hams, to quads to tibs.
The Tri-Flexor works great. I will say that it is a challenge to get my size 13 shoes strapped in and that is the only reason i only gave it 4 stars.
A review is on Trust Pilot. The equipment is nice except for the strap which is hard to put on. An adjustable clamp may be better. I also want COLOR. See the micro plates? They rock. They add energy to my workout. You can put color somewhere.
Awesome piece of equipment to strengthen muscles I wouldn’t normally be able to work.
Good stuff, works as expected.
Haven’t used the side bars, just the center bar for iso-tib work. Wish I tightened a bit better/easier around my foot (granted I’m using it barefoot).
Shipped to the UK within a week, no customs issue / extra costs required to receive product. Well built and easily secures to even my minimalist shoes (vibrams). One of the collars broke after a single use, emailed customer support and they shipped a new one out immediately at no charge. Really good service with a great product.
Fantastic!!! Very happy with the Tri-Flexor! Bonus... Athlete Freak offers exceptional customer service.
Great product! My son is a sprinter and we bought this to strengthen the ankles and tibialis muscles!
Tri flexor I ordered the tri flexor because I was having pain in my ankles and my shins. Since I’ve been using it for a few months the pain doesn’t get as bad after a long run.
Excellent Product! Great piece of equipment that performs exactly as advertised. I use my Tri-Flexor for tib raises, leg curls, and leg extensions.
Get superlegs at home! It took a month to get it delivered to Vietnam (via a forwarder) but it's worth it. I've been using a tib bar for a few months and the Tri-flexor is superior in every way. It's extremely versatile and well-designed. Stop reading reviews and buy this product.
Great tool I really like the Tri-Flexor. I use it almost exclusively for standing hamstring curls. I like how you get lots of the functionality of a leg extension/curl machine in a fraction of the space at a fraction of the cost.
Amazing Products I absolutely love your product(s)
Tri-flexor Doesn’t take up a lot of space, has multiple applications.
Great product! The Tri-Flexor is a game-changer. I use it at home and I take it to the gym where I train. It breaks down to a small travel size but it is durable, heavy duty. I love the versatility and ease of use. It’s given me the ability to really focus on weak links and hit them hard. Feeling great!
Tri-flexor Great product, excited to start my ankle strengthen and rehabilitation journey.
Makes my feet happy Love this thing! So far I’ve been using it for ankle exercises (basically ankle circles) and Tib raises. But I know there’s a ton more I’ll end up using it for. High points are: great packaging (not a scratch on it when it arrived), feels overbuilt (in a good way, very sturdy feel), and versatility At first I thought it could be overpriced but, given the build quality and versatility, I’m glad I bought it.
Almost perfect This product sounded like it was trying to be too many things at once, but after testing for a week, I am very satisfied with it. Solidly built and works every leg muscle you can imagine. Only complaint I have is the foot strap can get a little loose after a few reps. If there was a strap that went over the top of the ankle (similar to the Earthrunner huarache style sandle), it’d be perfect. Right now it just sits over the top of the foot and behind the ankle.
Tri-Flexor The Tri-Flexor is a very useful piece of equipment! I use it mostly to strengthen my ankles and hip flexors.
I love this It's my new go to work out while working at my standing desk. So versatile and useful.
Unique and useful I already had their tib-bar and like that. My first purchase was the Nordic bench which is great. This device has a lot of utility for different exercises I typically couldn't do. Use it for leg extensions, curls, and hip flexor raises. Very easy to switch feet, and add or drop, weight. Now that I have it, I'd really miss it, if I didn't have it.
Great lower body exercise tool There amount of different exercises you can do with this piece of equipment is literally only limited by you imagination Now that the IG algo knows what im into I literally find more ideas of great ways to rehab and strengthen every time I scroll through the 'Gram!! I really like the ease you can add/subtract the 3x poles...makes transitioning and moving much easier during workouts
Great If you are an athlete this is an amazing piece of equipment to have in your arsenal!
The best tib bar I've used tons of tib bars before, but the Tri-Flexor is the best there is! My ankles feel so much stronger after just a couple weeks of training. Great for hip flexors too!
Exactly what I needed My wife got me a bundle as a birthday gift and I love it. My ankles are particularly weak, so the triflexor been a huge help in my training. I'm excited to see what freak athlete comes up with next!
Does what I need I have always wanted to be able to work out my feet and ankles with a device like this. It is well built for a variety of uses, portable, and inexpensive. Also Benji is great to work with. I initially I bought the Tib Bar (also a great & very affordable product) but returned it once I discovered the Tri-Flexor, and he communicated with me well, making everything a breeze. I'm Looking forward to strengthening my feet.
Does what monkey feet and isotob does for ⅓ the price Refer to title
Benji was great to work with. I had some trouble ordering and Benji helped me out personally.
Liked it from a friend, would definitely buy 1 inch. Used a friends but please make a one inch model! I would totally use this all the time at home but all my plates are 1 inch (they were a little cheaper and i dont lift heavy enough that a 2" bar would do anything). Right now I strap dummbells to my foot with belt or flossband, works well but adds a lot of time that id love to save. This is the first all purpose product ive seen and I'd love to have something like this. Also if there was a 1 inch option for the sled that would be cool too, not a big deal tho cuz that looks easy to DIY. But yeah just a little suggestion.
THIS IS AN ALL IN ONE ATG PRODUCT! (BETA TESTER) finally a product that does all ATG movements on the lower body. was very fortunate to be an early tester of the product! has been tried and tested by over 50 people for the past month and still looks and performs like its brand new. will def recommend this to everyone! plus can use this barefoot and is comfortable.
Works wonders on my shin splints! I was super excited when i was asked to be an early tester for this product! Ive had shin splints for a long time and really weak ankles. This was an amazing tool to help me get out of years of pain!!
