Super intense workout with lots of motivational support. I joined their 30 day free fitness challenge, and on my 3rd workout, I could no longer bend down to sit on the toilet or couch. Getting up out of bed or my chair was impossible. So yes, you will get a massive workout. The only thing I don't like, which is just personal preference, is that you have to partner up with others when doing activities. I prefer an environment where I can stick my head phones in and work out solo. But that's just me. If you don't want to make friends and want to do it on your own, this is not the program for you. If you want to workout until you fall over, this is the place for you!!!
