My gym (Sats Elixia) has a number of training videos online for members who want to do training at home, with everything from tabata, cross training, barre to pilates.
In most of the videos there are three persons demonstrating the exercising, normally with mixed sexes. But the yoga actually has three men! If you have ever attended a yoga (or pilates) class, I’m sure you have seen that most of the participants are women. Men might perhaps think that yoga is not tough and hard enough for them. So perhaps the choice of instructors was to dispel gender stereotypes?
In any case, this was a nice and refreshing change.
