For a beginner to these exercises, I find the Nordic progression band to be quite helpful. I originally bought the nord stick without the progression band thinking that I’ll be fine. I’m an athlete. I probably don’t need it, but I was very wrong.
They’re clearly putting intent into their design and trying to make a good quality product. But as a product designer myself, there are few points that I think they could work on. 1) the stop they use to keep it jammed behind the upper part of your door is just webbing folded onto it self twice, I wish they folded it a few more times to make it more substantial. As it is now its actually insufficient for some doors, so be careful and mindful of how big of a gap you have on the upper end of your door and if your door can move as you're using it because believe me if it slips free while you’re doing the exercise, it will slingshot like a giant rubber band into your back, and it will hurt, quite a bit.
2) they have foam around part of the band to put behind your neck, but I wish they had more foam to also go under your arms. As it is now, the band itself isn’t comfortable to wear without a shirt, and even with a shirt on it, digs into my armpits and leaves a bruise. You can fix this by going to Home Depot and getting some soft foam insulation That’s normally used for copper plumbing pipes, but obviously when you buy a product you’re not literally looking to improve it you’re hoping that it’s good as it. However, I don’t know anybody else that’s making anything better and I think the product solves a real problem, so I would recommend with those few changes. But thats why i give it a 3 not a 5
