They all have different thicknesses that differentiate the resistance. They have a circular shape, not a strap. When folded, it measures 31 cm. That means if it is cut, it will become a 62 cm long elastic. Their material is very high-quality, it does not slip. I have been using them for about two weeks, but I feel that they do not wear out easily. They are suitable for various exercises, both with hands and feet. With a little imagination or searching on the internet, you can find many ideas. For greater resistance, you can combine the bands. I had knee surgery and I use the band to lift my leg (I place it in front of my toes and as it is stretched, I pull it to get on the bed without bending it). I want to say that these bands can be used for many things. So many words for a product that costs 3-4 euros... is it worth it?? Well, that's exactly why I'm writing this, because they are definitely worth it.

Resistance bands for various exercises. They come in different resistance levels and are conveniently packaged in a pouch so you can have them all together and not lose any. They are compact and don't take up much space.

It is completely subjective, of course, depending on each person's strength, but I expected the black one to be harder, especially. For Pilates and generally not very intense exercises, all colors are suitable! I do not recommend them for intense workouts with high resistance. The black one that I used for a while broke after several months of use, while bands from another brand have lasted longer, they just don't have as much resistance anymore. They definitely made their money, but now I have to buy a new one and I will not choose these again.

It is definitely not 1.20 meters long unless they mean if you stretch it a little before it tears. Also, it is not a single piece but circular. It seems to be for women's group activities where they put their feet inside. They definitely don't work for a man. Very bad purchase!
