The Ski Mojo my partner bought has been a resounding success, I’m happy to report. It took some getting used to, particularly in terms of putting it on - it nearly got thrown through the window in the early stages. However it’s now been on three holidays with us, and he skis all day without any knee/thigh/hip pain at all. He only started skiing 4 years ago, and he’s 65 years old - always has the intention to do all the pre-ski exercises but never really gets started in any serious way. Not the recommended way to do it we know, but many people are guilty of this! He already had trouble with his knees before taking up the sport, so the Ski Mojo is truly a miracle-worker. The main problem with it is that when it’s not attached to the ski-boots, there’s nothing holding it all in place. Doesn’t sound like a problem, but as it’s worn under trousers, you can’t put them on until the last minute before going out. If anyone has found a solution to this problem, we’d like to hear it. Looks weird, is quite heavy to lug around (we usually travel by train) and it’s not cheap, but we wouldn’t be without it.
