This month as well as dieting in an attempt to get healthy I've also been going to Power Box classes at Goodvibes.

I've been going with the Adidas press team, and I’m a total convert to the the gym kit they sent me, all the pieces are really comfortable and stylish to boot.

The classes are a combination of high energy boxing moves (punches, jabs, ducks and weaves) made tougher with the use of resistance bands, along with sit-ups, planks and squats on the vibrating plate. This has got me firmer in places I didn't know I could be. The real draw is that classes are a mere 30 minutes, (apparently comparable to 90 minutes in the gym, which I can just about believe) making them easy to slot in before work or during lunch.

To make a real difference to your figure fast, you would need to go to 3 classes per week for 6 weeks. Pre-book now for January and you'll have your New Year resolution all sorted before a mince pie has even passed your lips.

£20 per session or 10 sessions for £150 at Goodvibes
