When it comes to fitness, we can thank our friends across the pond for Barry’s Bootcamp, Soul Cycle, the Color Run (hence the irritating spelling), Insanity, #fitfam and countless other ways to sweat. It’s also safe to say, Californians were big fans of kale smoothies long before we caught on.

Yep, where America leads, we follow. So, as the US prepares to celebrate the fourth of July, we round up the newest trends that’ll soon be winging their way from Stateside to Merseyside.

1. Watermelon juice

It rehydrates, speeds up your metabolism and helps muscles recover post-exercise. It’s also a godsend on a hangover

Move over coconut water, there’s a new ‘it’ drink in town. Watermelon juice is one of those celeb trends – Leonardo Di Caprio is firmly on the bandwagon – quickly making its way down to us norms.

It rehydrates, speeds up your metabolism, and helps muscles recover post-exercise. It’s also a godsend on a hangover thanks to the electrolytes. The only downside is the price (watermelon juice is available in the UK for £2.49, 250mls, from Ocado). You’re better off buying a whole watermelon for considerably less and zapping it up in a NutriBullet.

2. Ropes and Rowers

A total body workout, it targets 84% of your muscles but without any pressure on your joints

CityRow has been making waves in New York for a while now. It’s a high-intensity, low-impact workout on beautifully made water rowers. Rowing is interspersed with mat work including free weights and bodyweight exercises. A total body workout, the 50-minute sessions target 84% of your muscles but without any pressure on your joints.

Fancy giving it a go? Swanky American gym Equinox has combined rowing and battle ropes (stupidly heavy ropes that you slam and wave for a killer workout) into one class to bring give you a double HIIT of strength and cardio. It’ll be available in the UK in September.

3. Insect protein

Cricket flour is the easiest way to get them down the hatch

Crickets are the next fit food trend – yep, seriously. Insects have twice the protein of beef and it’s the kind of protein you really want – the type that delivers all the amino acids you need to build muscle.

Cricket flour is the easiest way to get them down the hatch, lending itself to the likes of baking energy balls or frying up protein pancakes.  Bleee.

4. DNA testing

Finding the key to improving your fitness in a lab may seem like Frankenstein science, but it’s becoming increasingly popular as a method of understanding what makes your body tick.

The idea is to target your training to your genetics for your own personal best results.

Done properly, DNA sequencing can help you discover anything from how likely you are to develop cancer to how responsive you are to HIIT. The idea is to target your training to your genetics for your own personal best results.

Labs are popping up across America, but there are also some legitimate ones who give detailed results (which is key) in the UK too. Professor Jamie Timmons, the guy who scientifically proved that you can lower your risk of diabetes in three minutes a day, heads up XRGenomics who specialise in fitness DNA tests.

5. Hip-hop yoga

You flow in a dark, candlelit room to the sounds of some of Brooklyn’s finest

While nude yoga is taking off in New York, we doubt the UK will be embracing it with open arms and bare breasts any time soon. Far more likely is hip-hop yoga – the best-known class in NYC is, rather aptly, named A Tribe Called Sweat.

Mixing beats and breathing, you flow in a dark, candlelit room to the sounds of some of Brooklyn’s finest. Good news for those who find sitting still harder than sun salutation.

6. GM superfruits

It boasts more vitamin C than an orange, hitting your RDA in just a few bites

How do you make a superfruit more ‘super’? Well, the United States Department of Agriculture has just approved the country’s first GM apple. The Arctic apples keep fresh for longer once they’ve been sliced – so no more browning.

Meanwhile, the Zespri SunGold kiwi – originally from New Zealand but big in the US – is a hybrid of two kiwis. It boasts more vitamin C than an orange, hitting your RDA in just a few bites. It’s hairless, and yellow rather than green, and provides you with a higher nutrient adequacy score than blueberries, apples and strawberries. They’re already gracing the shelves, while the apples should be on sale by 2017.

7. Orangetheory

You tackle the treadmill interval, indoor rowing, and resistance zones hooked up to a heart rate monitor

Orange is the new stacked. First came CrossFit, next will be the HIIT heart-pounder from Florida. An hour-long group fitness session, the basic concept of Orangetheory is to make your way around a circuit compromising of three stations.

You tackle the treadmill interval, indoor rowing, and resistance zones hooked up to a heart rate monitor, which displays everyone’s BPM and percentage of max heart rate on a screen.

Your BPM will start in the green zone and the idea is to work up to orange – the colour that indicates you’re working in the prime-fat burning zone, 84-91%. There are already three David Lloyd Orangetheory gyms in London, with another opening in Winchester soon. We’re predicting they’ll soon hit the rest of the country.
