The latest fitness trends rely on teamwork and involve warrior dances, intense high-leg-kicking martial arts moves – or simply going for a roll around with your dog. Most surprising is the unstoppable rise in popularity  of team activities involving mud, obstacles and monkey bars – reminiscent of the ones we  tried to dodge at school. Here, Leonardo DiCaprio’s personal trainer Cornel Chin and  Mail on Sunday fitness columnist Gillian Reeves give their verdicts on which workouts everyone will be talking about  (if not actually doing) in 2014.‘Working out with dogs kills two birds with one stone,’ says Victoria Wills, founder of the Nubeginnings residential course. ‘A little canine company and encouragement is excellent for humans who aren’t keen on a training regime.’BENEFITS: The RSPCA suggests it is more likely that obese owners have obese dogs. Health risks  are the same for both, including diabetes and heart disease. ‘It depends on the level of exercise taken, but even a brisk walk increasing the heart rate is good for you and your pet,’ says Chin.WHO IS IT FOR? All dog owners.WHERE? nubeginnings.co.uk.  The next Paw Camp is in February.TONE AND TRIM WITHOUT LEAVING HOMEWHAT IS IT? Slim In Six is an  at-home workout which claims you’ll get in shape in six weeks. ‘The trend for at-home workouts shows no sign of abating,’ says Chin. ‘Slim In Six is huge in the US and taking off here. There are three separate sections: Start it Up, Ramp it Up and Burn it Up. You start with a low-intensity workout for 30 minutes a day with leg and arm lifts, moving on to bottom, hips and thighs toning with squats and lunges at speed. If you want to kick-start a healthy lifestyle, this is a fantastic at-home starter.’BENEFITS: Cardiovascular workout, weight loss and toning – at home.WHO IS IT FOR? ‘Suitable for most levels of fitness, but take medical advice beforehand. You need to be motivated, but knowing it’s within a short time-frame will help,’ says Chin. Great for those on a budget or short of time.WHERE? beachbody.co.uk, £66.80THE POST-FONDA WORKOUTWHAT IS IT? Burn 360 is a new all-over body-conditioning workout moving away from the Jane Fonda ‘bums and tums’ classes of the 1980s and 1990s.‘Burn 360 is based around stretching out all the tissue that surrounds and connects muscles,’ says Reeves (the class’s creator). ‘It gives definition and muscle tone as well as improving posture. 'The class starts with a stretching warm-up for the entire body, then focuses on different parts. Expect to find yourself doing body-weight exercises to strengthen wrists, shoulders and core. The aim is to move the body in all directions so that niggling injuries generally caused by our sedentary, desk or chair-bound lifestyles can be avoided.’BENEFITS: ‘Stretching is the best way of toning,’ says Chin. ‘Elongating muscles makes them look and feel toned.’WHO IS IT FOR? Suitable for all levels – but this is not a cardiovascular workout.WHERE? virgin.co.ukDISCOVER YOUR INNER WARRIORWHAT IS IT? Fierce, the African dance-inspired class. Reeves says: ‘Set to tribal rhythms, it’s an overall body workout with natural and bold movements that work the major muscle groups. It’s also great fun.’BENEFITS: Squatting, swinging and warrior-style kicking make this brilliant for toning legs, thighs and bottom.  Rhythmic stamping and pounding music are exhilarating, so it’s also great for stress-relief. ‘Most dance-orientated exercise has excellent cardiovascular benefits,’ says Chin.WHO IS IT FOR? ‘Everyone from beginner to professional,’ says Reeves, who adds that the class is as sociable as  Zumba and great for losing inhibitions. Fierce creator Teva Scarborough adds: ‘A lot of people believe they can’t dance if they are unable to perform the moves perfectly. If you look at traditional tribal cultures, everyone is involved in the dancing.’WHERE? virginactive.co.uk, from this monthBESPOKE TEAM CLASSESWHAT IS IT? Virgin Active’s latest piece of gym-floor kit, the Technogym Omnia, billed as ‘a revolutionary  Group Training Solution’.Capitalising on the success of their ‘Fast’ classes –15-minute trainer-led group exercise sessions in the main gym which can be dipped in and out  of by anyone – the Omnia is basically  a machine that up to eight people can use simultaneously.Each user stands at a station which can be fitted with different attachments that are pushed, pulled, twisted or manipulated in other ways. Some exercises use weights attached to pulleys, other require body weight only.BENEFITS: Instructor-led classes work strength, endurance, stability, flexibility, co-ordination and speed with toning  and some cardiovascular benefits. ‘Resistance training is excellent,’ says Chin. ‘It builds endurance, stamina, strength and body toning.’WHO IS IT FOR? Suitable for all  levels of fitness.WHERE? virgin.co.ukNO OBSTACLE TO FITNESSWHAT IS IT? Obstacle race courses for adults. ‘People have moved on from triathalons and want something even tougher now,’ says Chin. According to muddyrace.co.uk, last year there were 70 of these Ironman-type events across the UK that involved 200,000 entrants running three or six-mile courses, clambering over walls and obstacles along the way. The RockSolidRace in Exeter on March 15 is  a good example – you’ll plough through mud, swamp and water.BENEFITS: An all-round cardiovascular and strength-building workout. Train with moves such as pull-ups and press-ups,  or circuit classes at the gym.WHO IS IT FOR? If you fancy yourself  as a bit of a part-time action hero, and think marathons are for wimps, then these are the races for you.WHERE? muddyrace.co.ukWHAT IS IT? Tabata classes are  20-minute sessions that include 40 seconds of intense cardio with exercises such as transverse jump and sprawl (falling into the press-up position and to your feet again) and ten seconds of rest in four-minute cycles.
