Here are the newest workouts focused on community, technology, and restoration that are motivating more people to exercise.
1. Classes that burn massive amounts of calories

High intensity interval training (HIIT) still rules the number one spot on the American College of Sport’s Medicine’s list of the most popular fitness trends for 2018.
hat’s not surprising, as everyone wants to walk into a class and get the maximum results for their efforts, says Burn 60 master trainer, Andrew Schuth.
Classes at California-based Burn 60 follow a format that alternates between bouts on the treadmill and functional training intervals on the floor all under the watchful eye of the trainer.
While one group is burning it up on the treadmills, the other is on the floor performing exercises, such as one-minute of burpees, and using various types of equipment.
“We do different moves to create muscle confusion and we try to keep you moving so your heart rate is elevated and you burn more calories,” says Schuth.
Participants can expect to burn anywhere from 500 to 900 calories during the one-hour class and see results within the first two weeks
2. High intensity training in the pool

When it comes to aquatics there has been little innovation—it’s either laps or water aerobics, says Rob Glick, senior director of programming and innovation at US-based Life Time Fitness and co-creator of WTRX (Water Xtreme).
A collaboration between Speedo and Life Time Fitness and taught by certified instructors, the classes use newly developed Speedo aquatic training aids, such as the Push Plate, to add resistance in the water and increase the intensity of the workouts.
“We worked with Speedo and came up with an ultimate boot camp that takes place in and out of the pool,” says Glick.
About 75 percent of the class is spent in the pool performing high intensity moves while the rest of the time is spent on deck performing traditional exercises such as push-ups, lunges, and triceps dips.
“High intensity moves done in the water are less stressful on the body, and water classes aid the body in recovery,” he says.
3. Yoga alternatives

Yoga in both its traditional and alternative forms remains a popular fitness trend for 2018. One of the most popular classes at Life Time Fitness, Warrior Sculpt, keeps in step with the demand for alternative yoga classes by offering a fusion of yoga and strength training using light weights.
Most yoga classes already have a significant amount of resistance training – lunges in warrior pose and push-ups through chaturanga – but they are not recognized as such, Glick explains.
“Warrior Sculpt complements your typical yoga practice while increasing your strength and flexibility and boosting your metabolism. The movements are intuitive, intentional, focused, and purposeful,” he says.
