I originally bought it but mainly to strengthen me for my running training. And here I can connect some of the previous speakers, I think it it depending on your body stature moderately suitable. I weigh 82 kg at 1.85 m height and can not make tight enough so that it is firmly seated in running it. A lifting of the vest in the rapid upward movements and falling back on his shoulder and chest is very unpleasant. So far I could also not a add. Create sweatshirt or a running jacket remedy. And 4 layers outerwear, so the vest sits me are then too much :).
Maybe I find this still a viable solution, but at the moment has to be run without vest halt.
For strength training, however, recommended by my side without restriction!
