Nordic Hamstring Curl Strap with Safety Tag (DON’T OPEN), Sozzy Upgraded Heavy Duty Leg Curl Rated Up to 500lbs, Adjustable Length, Great for Hamstring Curls, Sit-ups, Spanish Squats, Ab Workout

This thing seems super solid. The strap is solid and the cam buckle is smooth. Appear well made.

So what drew me to this item in the first place was its ability to aid in Nordic hamstring curls. I have a really weak posterior chain and have trouble isolating certain muscles in order to actually strengthen them, the hamstrings being one of those muscles. I wanted to start doing the hamstring curls to help with that, and this is a great solution to the issue of finding something to hold my feet down while I do it. The padding is thick enough to be reasonably comfortable. It also unexpectedly helped with another problem I was having- my squat form. Again, because of my weak posterior chain combined with my poor ankle flexibility, I struggle a lot with getting into a low squat without my heels coming off the ground. When I try to lean back more to correct this, I often fall backwards. The padded piece that sits behind your knees keeps me from falling without having to hold a dumbbell in front of me to counteract the weight. It could be just a little wider to allow me to widen my stance a bit, but it still has been tremendously helpful for keeping proper form and activating the right muscles. I'm excited to try it with other applications, such as ab exercises.The strap seems well constructed and strong. It stays wedged in my door well and I feel safe with it bearing all my weight. The 'do not open' warning on the wedge piece that sits on the other side of the door is a nice touch. Although I use it on my front door and keep it locked while doing so, it's nice to know I can use this on other doors if need be and have that added protection of deterring someone from opening the door while I'm using it.

To better set the expectation here, this is a Nordic hamstring curl strap. It is in no way a complete home gym. It is well engineered and made of quality materials and does exactly what it was designed for--facilitating Nordic hamstring curls. I had originally ordered thinking the possibility of a gym in a bag that would provide a through workout when away from home and a good supplement to my home routines. It definitely facilitates hamstring curls as you'd imagine but some of the other exercises the instruction book lists can be performed as well if not better using your own body weight without the benefit of this strap (i.e., pushups, squats, crunches, etc.). With that said, I do like using it for sit-ups rather than cramming my feet under a bench or couch. The strap adjusts very easily and smoothly to whatever length is needed. Once adjusted, it doesn't slip when in use. Additionally, the included travel bag is also a nice touch and the strap itself, packs very well inside it.All in all, this Nordic hamstring curl strap is a good value and made very well if a hamstring curl strap is specifically what you need or want. This strap would be a good addition to most home gyms for specific exercises it was designed for. On the other hand, keep on looking if you are looking for a total gym experience in a bag as this is not that.

This hamstring Strap is easy to use. Just slip the Don’t Open part of the strap under the door and close the door. Adjust the length. You can adjust it shorter to use for Ab exercises or longer for various other exercises targeting the hamstrings. The strap is sturdy. The foam pads are good but after a while it seems they will break down with all the pressure on them. Please be aware that if you use this tool for your hamstrings that you should be an intermediate in your workout background. Beginners could easily hurt themselves if they do not have some basic strength already in their hamstrings. Don’t jump right on to this device without already building up your hamstrings. It is a good for travel and home use but not for the gym.

I think this is a really well made and thoughtfully presented item. First of all, it's really strong. I checked out all the stitching, I yanked and stretched and tested all the parts of it and this thing isn't going anywhere anytime soon. It's solid.Secondly, I'm a big fan of writing "DO NOT OPEN" on the part that sticks out the other end of the door. The way that this works is that you put part of it under the door and it lets you use the door and frame for stability so you can do a variety of exercises at home. But if someone opens that door at the wrong time or during the wrong exercise, you can probably hurt yourself. So a big, clear warning to others that now is not a good time to open the door is a really solid idea.I like how clear and easy the instruction booklet is and how well the information is laid out. You get directions on how to do several recommended exercises and there's clear information about how much weight this can support. How much weight your doorjamb can support is a different matter entirely, of course.I had to wait to use this due to a knee injury sustained almost immediately after ordering it but I'm looking forward to incorporating it into my recovery and using it to do some of my physical therapy exercises.
