yup at least once a week now part of my rehab got an op on my knee , about 20 people normally in the class and about 3/4s of that are women cany go wrong lol
Watched my ex bird do it from the bar in the gym... looked hard work lol. But in all seriousness, she used to really enjoy it and it appeared to work well; quite a few of the backs up the rugby club used to do it too with great results. If its free, no harm in trying it out bud
