Online coaching works well if you can train at home, in a gym or a mix of both, but you find it hard to stay consistent without a plan and a check-in. It's also useful if your week changes a lot and you need training to flex around it.
If you need hands-on technique coaching every session, start with 1-to-1 PT or choose the hybrid option. If you feel fairly happy training on your own but want direction and accountability, online coaching is probably the better fit.
You don't have to be perfect with the plan for it to work. If a session gets missed, we'll adjust and keep moving rather than starting again from scratch.
