the short answer
To name a personal training business, pick a style that fits your ideal client - motivational, name-based, location, performance, premium, or playful - then brainstorm 15-20 candidates, say each one out loud, and check that the .com domain and the Instagram and TikTok handles are free before you commit. The best name is short, easy to spell, clearly signals who you help, and is available everywhere you need it.
Use the 80+ ideas below as starting points to remix, not names to copy outright - always run your own domain, handle, and trademark checks before you commit to one.
