Long gone are the days when exercising meant going for a jog or heading to the local aerobics class.

These things still exist of course, but not quite in the same way - aerobics now means a long list of pump-it/dance-it/blast-it/shake-it-to-the-beat variations, there are all sorts of fancy gizmos and disciplines for strengthening up and, while jogging might still essentially be the same, look at how many people are now ‘training’ for an event, monitoring progress on smartphones and investing in the latest gravity-defying trainers.

Certainly, we’re spoilt for choice these days when it comes to how we exercise. 2014 saw high-intensity interval training [HIIT] become mainstream, ‘personal bests’ are something everybody - not just pro athletes - think about, and getting-my-sweat-on overtook pouting-on-a-night-out as the social media selfie of choice.

According to the trend forecasters, there’s more to come in 2015.

Here’s a snapshot of the fitness vibe predicted for the year ahead...

TIME AND CONVENIENCE TOP THE LIST “We’re increasingly time poor,” says Dave Kyle, head trainer for Les Mills UK. “We’re working longer hours than ever, so finding time to work out can be increasingly difficult.”

So as time is at a premium, the industry’s catering to our needs by increasing short yet effective workouts.

ANY TIME, ANY PLACE Fancy pumping iron at 2am? Hitting that treadmill at midnight? No problem - it’s getting easier to work out around the clock, and PureGym, the UK’s leading 24/7 gym, now sees 20% of its members training at night, so those working shifts, for instance, can still benefit.

LET’S GET FUNCTIONAL In 2014, you might well have found yourself scuttling across the floor like a lobster or leaping around like an ape - primal movement-based exercise might sound like child’s play but it sure does burn up those quads!

In 2015, the trend’s set to develop further, with functional training putting a big emphasis on widening our range of movement and offsetting the damage of sedentary lifestyles.

STRONGER THAN YESTERDAY More women than ever have started including weight training into their fitness regime; could our ‘I’ll look like a bodybuilder’ fears finally be gone for good? A beautifully honed bicep and sculpted quads are now the most envied curves in town.

2015 TREND TITBITS What else is on the fitness horizon for the year ahead?

n Variety – forget sticking to one or two forms of exercise. The choice of classes and facilities has never been so vast and people are cottoning on.

n Doing it for the kids – more focus will be put on catering for youngsters and families.

n Channel your inner athlete – with London 2012’s legacy still going strong and more of us signing up for challenges, you’ll find plenty of ways to train like the pros.

n Outdoor training – getting outdoors to exercise means vitamin D top-ups, fresh air in your lungs and an extra sharp endorphin rush.

n Make a splash – swimming’s the UK’s most popular sport, in terms of participation, with around 2.9 million of us taking a dip at least once a week. It’s a fantastic, low-impact, whole-body workout and even more of us are expected to take the plunge in 2015.

n Tech me as I am – apps, gizmos and gadgets galore now play a key role in our fitness habits, and in 2015, it looks likely that tech will continue to help us monitor progress and smash those goals.

n Regeneration – a growing buzzword, that token 60-second warm-down won’t cut it in 2015; anybody worth their moisture-wicking threads knows that helping those muscles heal is just as vital as how many reps you managed. What do you mean you don’t own a foam-roller yet?!
