I felt the same paralysis of making decisions and figuring out the right exercises to do. So I got a personal trainer through an app and it was game changing. They would send me encouraging texts and give me some accountability and do the hard work of coming up with exercise routines for me so I didn’t have to think about it. It was pretty expensive so I switched to a cheaper app that doesn’t have 1 on 1 support and customization, now that I have some confidence in myself and my ability to do it.
The first app I used was called Future and the one I use now is called Ladder. I do weight lifting and some cardio but both apps have a variety of stuff, Future more so because the trainers can totally customize anything.
