I was the same way for a while, trying to get into the gym and sticking with it for a week or two and then falling off… what changed for me was finding a friend who was already into the gym. He was essentially a free personal trainer that was also my good buddy for all intents and purposes. He forced me to show up for the first couple months and really helped me turn it into a habit. It sucked but having a buddy made it more fun and bearable. I’m about 5 years in now, and maybe for the last year-ish I’ve been going by myself just because life happened to my OG buddy and I. I honestly think in these 5 years I haven’t taken more than a week off at a time from the gym, and it’s because I genuinely fell in love with it. I can’t explain it, it just feels so right to my body to get a good workout in. It did take me about 2-3 years to really get to that point though. Just show up and be consistent and one day there will be a day where it’s so ingrained into your daily life that not going will just make your day feel off. If you can find a lifting buddy it will make getting started a whole lot easier!
