Strip us down to the suits we were born in, and it’s plain to see that nature has endowed the two genders differently. Go further than skin deep and you’ll find even more differences, not all of which you can see with the naked eye. Those variations mean that when we exercise and eat, men and women need to take a slightly different approach.

But are we really so different? Where does it say that the free weights area of the gym is a testosterone-only zone? Where does it say on the class timetable that yoga is just for the ladies? It doesn’t.
