The Hottest Workout of 2019 Is Coming to a Living Room Near You

The leader in this industry has to be Peloton, and the company's success is only continuing. "We sell a bike to every state every day," a spokesperson told the Wall Street Journal. This past year, Peloton augmented its repertoire of Spin bikes with a new $4,000 treadmill — a sign executives feel confident in the rise of the on-demand workout trend as well. In addition, the $4 billion company's subscriber base has increased to one million.

Knoxville, TN-based fitness influencer, entrepreneur, and mother of two Sarah Stevens told POPSUGAR she uses her Peloton bike at home, in addition to a ProForm treadmill and other on-demand fitness apps, because it helps keep her on track when she can't make it to a 5 a.m. exercise class.

Studio Tone It Up — the Tone It Up fitness brand's on-demand workout app — has been on the rise in 2018 and shows no signs of stopping. Creators Katrina Scott and Karena Dawn have seen the cultural shift toward on-demand begin to happen this year; Katrina told POPSUGAR that subscribers — particularly moms — have told her that they've "canceled their gym membership because the app is more accessible and easier to fit into their lifestyle." (By comparison, the app costs just $13 per month or $84 per year.)

Studio TIU allows community members — regardless of geographic location — to schedule workouts, which helps keep them accountable (a challenge with home exercise) and also allows them to feel like they're a part of the trendy fitness scene.

Tonal is the home gym of the future: an all-in-one, multipurpose, minimally invasive piece of equipment that pairs electromagnetic resistance with on-demand coaching. Think Peloton but for strength training.

"Once you choose a [Tonal] program, you have a world-class coach on screen the entire time guiding you through each movement, providing you with encouragement, jokes, form corrections, and the motivation to allow you to give your best effort and achieve your best body," Tonal's founding coach Liz Letchford, MS, ATC, told POPSUGAR. The wall-mounted system will cost you $2,995, plus a monthly subscription.

Tonal's interactive approach to "muscle-building, fat-incinerating, metabolism-boosting strength training" fills a void in the at-home market, Liz explained. "Nothing else has come close to helping people bring the entire gym — your barbells, your strength machines, your dumbbells — home."

You've had a Fitbit for forever — it's time to kick things up a notch and try Fitbit Coach, the brand's premium, on-demand service offering customizable workout plans that are tailored to your physiology, goals, and preferences.

Choose between quick 7-minute workouts or sweat it out for a full hour; the Fitbit Coach program recommends equipment-free bodyweight workouts that "adapt and evolve based on your Fitbit activity." It's like having a personal trainer create a plan for you but way, way cheaper. A year's worth of coaching is only $40.

Treadmills are coming back in a big way, and ProForm has been a leader in this space. With a model starting at just $1,399, ProForm's smart treadmills cost half as much as their biggest competitor and include iFit coaching on the screen for at-home cardio workouts.

ProForm has also been targeting fitness influencers in smaller markets, including Sarah Stevens. She told POPSUGAR she's noticed the increased interest from her followers when it comes to at-home equipment and has been using the ProForm as a complement to her Peloton and fitness app-based routine.

Your go-to exercise videos at Class FitSugar are getting even better in 2019. Join the 30 Days to a Flat Belly program ($8, originally $10), and let Anna coach you through the month to a stronger core and healthier body.

Like ProForm, NordicTrack has also tried influencer marketing, specifically for its treadmills, generating a strong following among the fit-focused Instagram community. But it's not just treadmills — NordicTrack sells indoor cycles, ellipticals, rowers, and incline trainers.

These high-tech home gym machines also incorporate iFit coaching programs on the screens to keep what could be a stale cardio workout fresh and engaging. And you can start your home gym for less than $1,000, which is about the cost of a moderately priced gym membership for a year. Plus, with the at-home coaching, you can get your ultrasweaty workout in without worrying about bringing your gear to shower and change afterward.

If you're not ready to bring equipment into your house, or you simply want more variety than a treadmill or bike can provide, Gold's Gym now comes home in your pocket with the Gold's AMP app, which provides audio and video coaching and a variety of workout styles.

And if your favorite part of going to a fitness class is your instructor's playlists, then you'll love AMP. The music-centric app generates high-energy playlists that are updated weekly to keep your workout feeling fresh.

Even the busiest people on earth can take three minutes to sweat to a dance cardio video. Caleb Marshall, founder of The Fitness Marshall — an on-demand, YouTube-based dance cardio channel — told POPSUGAR that his subscriber base has increased 50 percent over the past year, and he's projecting even more growth in 2019. Why? Mass appeal and fun.

His dance videos are beginner-friendly (he told POPSUGAR that he ensures his dances are simple enough for his grandma to follow along) and only three to four minutes long — and they're all in good fun. Fans of his program gravitate toward his silly personality and magnetic energy as he coaches dancers through the sweat sessions. TFM videos are 100 percent free and all on YouTube, making them exceptionally accessible.

If you've got Pilates equipment at home — or if you love mat Pilates! — you're going to want to check out Pilates Anytime. The program is $18 per month and gives you access to some of the world's best Pilates instructors. From Lisa Hubbard to Rael Isacowitz to Courtney Miller, you can have big city Pilates classes no matter where you are.

Kayla Itsines revolutionized at-home exercise with her BBG program, but she and her business partner Toby took it to the next level with SWEAT: the on-demand exercise app that provides a complete program of your choice, including water tracking, meal plans, and community check-ins.

The brevity of SWEAT workouts is what makes the programs so popular; most people have 28 minutes in their schedule, and many of these at-home routines are equipment-free. Plus, at $20 a month, it's the financial equivalent of one Starbucks coffee a week.

Daily Burn provides a 30-day free trial, then it's $15 per month — much less than the cost of a studio class, let alone a month's worth. The brand also has a HIIT app that gives more of a one-on-one experience to complement the group class videos provided on the main platform.
