Personal training services? Workout gear? Not sure you should have lead with that, these are expensive things with minimal impact.
For example: societies that live the longest and are generally the healthiest do not have gym equipment or trainers, exercise is a core part of their every day life.
The mistake you are making [I think] is looking at these things as impossible goals because of lack of more money so it is easy not to try and risk failure.
If you're not wealthy you can do them, but you have to sacrifice other things, and some of those you wont be able to afford.
