Alison Hammond, 51, is maintaining her stunning 11 stone weightloss with a rather unexpected workout routine. The presenter was pictured working up a sweat during a gruelling boxing workout on Instagram, sharing a video with the caption: 'Yass @themccannic ! Same time next week'. Personal trainer and boxing tutor Stu McCann - aka @themccannic - could be seen sparring with Alison as she punched pads and powered her way around the room.

Boxing is the latest fitness chapter in the presenter's incredible weightloss journey - and it's the perfect exercise for anyone looking to burn calories. 'Boxing is a surprisingly brilliant way to get moving and feel good,' says Kim Hawley, GH's fitness expert.

'Boxing for fitness isn’t about stepping into a ring or investing in a mouthguard. It’s the training that does the magic and keeps the brain ticking as much as the body, with drills to learn, remember and build on. Add in footwork and suddenly you’re working coordination, balance and focus all in one go.

'It’s a proper workout too. A few rounds of punching thin air will have your heart racing, and even basic simple skipping does wonders for cardio and bone strength –you can even “air skip”so you don't even need a rope! Unlike sports that rely on courts, clubs or other people, this is something you can dip into whenever you like.'

You don't even need a sparring partner, says Kim. Shadow boxing - where you punch, defend and move as if you're fighting an imaginary component - boosts heart rate, builds core strength, improves technique, and burns calories while acting as a major stress-reliever.

There are plenty of ways to try boxing - whether it's in a gym, at a class, with an online shadow boxing workout, or with a one to one tutor like Alison. 'It’s genuinely fun,' says Kim. 'If you’re looking for something a little different for your health and fitness routine, boxing might just land the punch.'
