Fancy a novel way to shift the pounds? Try these top workouts to get f

January is the time of year when we often fork out for expensive gym memberships that we'll probably never use. But to avoid slipping into this trap personal trainer Matt Roberts, whose

past clients include Naomi Campbell and David Cameron, says trying something new and varying your workout is the best way to achieve your fitness goals. "The key to a successful

fitness regime is to keep doing different things," he says. "Think about exercise the same way as you would food. "If you ate the same thing all the time you would soon get

bored." Here are Matt's hot new trends to look out for in 2015. Forget about Zumba classes and indoor cycling, this year is all about one-of-a-kind experience exercise classes such

as trapeze and ballet-inspired workouts. "Currently more and more people are moving away from traditional gym workouts in favour of more unusual exercise classes," says Matt. Last

year saw the emergence of this style of class - such as BARRETONED - but in 2015 people will be taking it to a whole new level. TRY: HOT BALLET Taylor Swift and Katie Holmes may be fans of

the more traditional ballet-style classes but this new style is taking the classic ballet moves into a warmer environment. Ballet Tone at Good Vibes studio in London uses infrared lamps to

heat the room to 27 degrees and SAD lighting to boost your mood in the dark winter months. As well as increasing your suppleness and flexibility the temperature allows your muscles to warm

up faster and helps to prevent injury. This year we aren't just getting in shape to look good. We are doing it with a specific goal in mind whether it's to run a marathon or

complete the Three Peaks Challenge. "It is now about taking part in something bigger," says Matt. "A trek, mountain climb, triathlon, duathlon or similar events are becoming

the norm among the exercising set." Luckily fitness classes are now offering whole-body strengthening workouts as part of their routines to help us reach these personal goals. TRY: THE

GRID Launching in Virgin Active gyms nationwide this month, The Grid incorporates functional fitness moves such as squatting, pulling and lunging to teach the body to handle real-life

situations. Andy Birch, head of exercise and wellbeing at Virgin Active, says: "The future of fitness is a whole body workout, not just honing in on one aspect of training." Choose

from four classes which all promote flexibility and motion. They are available nationwide. For more information visit virginactive.co.uk. Thanks to social media you can now have a personal

trainer on call without leaving the comfort of your home. If you are signed up to Twitter or Facebook, you can receive tips and coaching from experts, watch tutorials and download classes to

take in your free time. "Tune in to leading instructors, nutritionists, yoga and Pilates teachers' live shows and take part in sessions that would otherwise be out of your

geographical or financial reach," says Matt. TRY: LDN MUSCLE Want the personal training experience but can't afford a personal trainer? LDN Muscle has created week-by-week

throughout 2015," predicts Matt. TRY: ORANGETHEORY High-intensity interval training (HIIT) is perfect for those who want to burn a lot of fat in a short space of time. HIIT involves

bursts of intense exercise followed by a short rest. David Lloyd Leisure has launched a set of training classes called Orangetheory Fitness. George Rounthwaite, studio manager at David Lloyd

Islington, says: "Orangetheory classes are different every day of the week. "The classes last for one hour. "The first half is dedicated to interval training mainly using

treadmills while the second half concentrates on full-body resistance training. "The classes provide a full-body workout for those short on time and you can burn between 500 to 1,000

calories per session." Each participant is hooked up to a monitor and your heart rate appears on a big screen so there is an element of competition about it as well. Now available

nationwide. For more information visit the website davidlloyd.co.uk.
