It turns out Pippa Middleton is keeping in shape with British Military Fitness - the company that treats regular people like actual soldiers so they can run the length of themselves without needing a sit down.
It's a rigorous workout but is anyone surprised Duchess Kate's little sister does more than just a half-hearted hour on the cross trainer? The 30-year-old basically looks like the healthiest woman in Britain - it's enough to make you immediately sign up for the company's workouts too.
1. You have to wear a bib - like back at high school PE - and this signals your level of fitness. Please, please believe me when I say no matter how much you may be tempted to go with your ego on this, just be honest. Here's how to gauge it: if you go to the gym three times a week, you should be in the less fit group.
2. Several ridiculously fit ex-soldiers shout at you loads. This is confusing, because before the class starts everyone's just standing about at the meeting point - usually near a park - having a nice chat. It's like you've been friends forever - people are so pleasant. But then the session begins and all the yelling reminds you these are genuine hard men. Things get so military-esque and serious, you* feel quite silly for telling the instructors you spent the weekend trying to make custard.
4. It is an amazing workout. At one point, I felt like I was going to vomit from sheer exertion - that has never happened at the gym. This may not be such a good thing but it definitely made me realise I probably needed to put more effort into my regular routine.
5. Everyone goes to the pub afterwards! Well, they did after my class and that was quite nice. Although, order a soft drink - a glass of wine is not what you need after this.
