Thanks to social media we have direct access to top trainers and nutritionists who regularly spurt little nuggets of health-related wisdom, so we’re not only more educated on exercise and eating well, we’re also inspired to take part. But, with so many plans, guides and programmes on the market, how’s a fitness enthusiast supposed to know which is best to invest in?

That in mind, we squatted and sweated our way through workouts from some of the best guides around, taking into consideration the duration and difficulty, the fitness level required for the exercises involved, the guidance and support provided, plus the functionality of the source (how easy the website, etc, is to navigate). Our favourites, listed below, include sessions from top trainers around the world.

Some are based in the US. This means that, although there are no additional charges for purchasing the programme, the cost may vary depending on the exchange rate at the time. It’s also worth asking what your bank charges for foreign purchases, as it may cost you a small percentage of the fee.
