Good
The best workout apps I've found so far. Wish there was a bit more versatility in the strech app and kettle bell app though. And the kategories that tell which excercises are easy or difficult don't always make much sense. Some that are labeled difficult are pretty simple and then there are some excercises that require both technique and musclestrenght to be performed safely aren't labeled difficult (eg. Jackknife in gymball app). But all in all. I like these apps. I have purchased several. :)
