There is also solid instruction for each of the trainer-led workout videos. If you’re a cyclist, or any endurance athlete, a great app for tracking your bike routes is Strava. Not only is the GPS tracking pretty accurate, but there is a social element that separates it from most other free cycling apps. Each exercise has an extensive overview of the movement, including a video, complete step-by-step instructions, a muscle map displaying the body parts most involved, and even key points and takeaways on form. That’s a lot of information for each exercise, leading us to rate the instruction a 5 out of 5. Some gyms also offer body scans for detailed body composition breakdowns.

The best part, though, is that it’s completely free—no monthly subscription or hassle to cancel should you decide it’s not for you. Whether you’re hitting the weights in the gym or at home, a workout app is a great way to guide you toward your fitness goals.
