The device can be easily installed in the door frame and there are enough settings for a variety of exercises. The straps and hooks to make a strong impression, I have the training never feel that anything is unstable. Since my door is not however the most stable, I have put a big sofa cushions on the floor for safety, happens for the "worst case scenario" is so far fortunately nothing.
Although I'm used bodyweight exercises, urges the Slingtrainer also advanced. The big advantage is that the exercises can be adapted only through a change in angle in their difficulty. Exercising can be all muscle groups, so it is a full body workout possible. The big advantage over machines is that the entire body is a lot more required, which ultimately leads to a strengthening of trunk and abdominal muscles.
Overall I am very satisfied with the device, a demanding and time-saving training (compared to the gym) is thus entirely possible. I know nothing that would make a much more expensive Slingtrainer better, but this is also the first Slingtrainer, I use.
