Aaptiv

Aaptiv is unlike the rest of the services on this list in that it is audio-only. What makes it so great is that you can use Aaptiv to coach outdoor workouts, including running and cycling, and workouts on a treadmill, exercise bike or elliptical. Aaptiv also has classes for yoga, strength training and other indoor workouts.

All told, there are about 2,500-plus workout classes, with around 30 more added weekly. You can pick workouts based on time, difficulty level, trainer and even choose the music you want to hear. If you ever need cues on how to perform an exercise more, you can use Aaptiv’s visual workout guides which show you how to perform 250 movements, such as deadlifts or dumbbell rows.

It costs $100 per year with a free seven-day trial or $15 per month (without a trial).
