No judgment. You're not the first. Let's figure out what's actually in the way.
Is it the schedule? There's a class time that works. Monday & Wednesday: 5am, 6am, 9am, 12pm, 4:30pm, 6pm. Tuesday & Thursday: 5am, 6am, 9am, 4:30pm, 6pm. Friday: 5am, 6am, 9am, 12pm. Saturday: 7:30am and 9am.
Is it the kid logistics? Childcare is included for your first class, free. You don't reserve it — just show up. Drop the kid off, drop your bag, walk in.
Is it the gym anxiety? Real. Common. Solved by walking in once. The thing you're picturing in your head is worse than the actual thing. You'll know that within 10 minutes of being on the floor.
Is it "I forgot"? That's the most common one. So pick a class right now and put it on your calendar like a doctor's appointment.
Pick the time that's hardest to skip. For most people, that's the morning before work or right after drop-off. Anything you can put between yourself and the rest of the day is a class you'll actually attend.
