This one’s especially for the girls – a ladies-only bootcamp that’ll give you pounding fitness sessions and body toning, but also nutrition advice to complement your workouts.

You’ll get expert tips and targeted classes from celebrity trainers Tim Drummond and Phil Hawksworth. But it’s not for girls who’d rather not get sweaty – the “warrior-style” regimes are fast and intense. With just two 30-minute sessions per week, the aim is to achieve the best results in as little time as possible. Expect free weights and tug-of-war regimes as well as medicine balls and more traditional strength exercises, which focus on tough spots like the waist, thighs and arms.

Nutrition plans with daily menus and extra exercises focused on a specific area are emailed to members three times a week, to make sure they stick to the program – so if you need to have someone on your back at all times, this is the regime for you.

Sessions are at 8am on Tuesdays and Thursdays and at 5.15pm on Monday and Wednesday. The programme costs £99 per month. And we thought it was too late to get in shape before Christmas …
