Simple and effective
I absolutely love this app! I have been wanting to do a course or teaching with Wim Hof (and still do) but this app teaches the basic techniques simply and effectively. I have already seen huge improvements in my own ability.
Only one "bug" I have noticed, not really a bug though... The videos for the Headstand and Shoulder stand are mixed up.
