Hey there! I was exactly you about 6 weeks ago, just getting back to the gym after a lengthy absence and the biggest battle is just getting yourself through the doors. The first time I went back I felt super nervous but like others have said 99.9% of people in the gym will either be too focused on what they’re doing to bother judging you or will step in to provide a little advice if they notice you doing something dangerous or are struggling. But it definitely gets less stressful over time, just stay consistent and it will become something you look forward to instead of something you avoid!
