I ordered the set, because I want my fitness a little step up. I go for walks and do well Inddor-Walks. On the treadmill now I try to run but while the arms are a little neglected. Since the light dumbbells are entirely appropriate. The leg weights I use currently is not, since I'm a beginner and so am already after 20 minutes at my limit. But if I have built up some stamina, I will also use these weights. I've tried them - they fit perfectly around my ankle. Since they are adjustable, we can use all the weights. The only downside is in the light weights that they absorb the sweat like a sponge. Actually an advantage because it is simply run me in the other weights the arm down but on the other hand I think it's a little unsanitary. Otherwise - Top Products!
