Depends on your goals and income level. I couldn’t afford to rent a place with the space for the equipment I use let alone the equipment itself. Of course training isn’t required for anyone, and there’s a lot you can achieve with little or no equipment, but there’s a reason why people pay for gym memberships rather than simply “doing pushups at home”.

There’s a lot more to training than push-ups

Or point a very powerful laser at them

I’d also recommend something like scratch. If these people are non-technical as you say, they might not understand the concepts of directories on a computer, zipped files and so on. You’d be risking spending your teaching time troubleshooting the setup process and losing their interest before they ever get to write a line.

Of course that’s just based on how I interpreted your post, you know best their potential skill level.
