I've been using this workout app called Hevy, for about a year now and it's been amazing. I'd recommend it to anyone who wants to start working out but feels like they wouldn't know what to do. When I first started going to the gym, I was googling every workout until I knew how to do them on my own.
Hevy has all the exercises with video demonstrations and you can filter them by the muscles they target. If you do any exercises at home or outdoors, you can create your own exercises and add them to the app. It even tells you what weights you could move up based on previous workouts.
You basically create your own workout plans and track your progress.
There's also a social aspect of the app where you can follow friends and try their workout plans or anyone else who you feel has the same fitness goals.
Sometimes I’ll get a notification that a friend just posted a workout and it’ll motivate me to wanna go more. And the records and encouragement slides they do are pretty cool. Definitely worth checking out.
