First off I have no clothes you’d ever wear to a gym. I wear jeans and a t shirt pretty much daily (think Hank Hill). Second, I don’t get what you do there. I hated gym time in school (workout gym, not like throwing balls and running around gym, thats fun) and I don’t get what you do. Run on a treadmill and lift some weights? I feel like I could do all of that at home. Gym memberships are insanely expensive. Are home workouts actually effective? Does one even enjoy gym time?
The first visit to a gym could be free. Or it can be a “a current member can bring one friend for free once a month” thing. You can just go and check what’s out there. Most people probably just lift weights or use the machines that they don’t have and don’t want to buy at home. There’s also the factor that if you’re at the gym, you’re there to work out. When you’re at home, you can be distracted by whatever.
