I had no idea the personal trainers are as qualified as MG noted (mostly because I never used one)
That said, you can still offer your service as a trainer, and charge 10-20% less than the professionals do, untill you get the necessary training.
As long as you are honest about what you can and cannot offer, there is a market.
What I meant by “meet in park” was instead of training indoors, an outdoor park will give the client a chance to see what she can aspire to, if she sticks to a training regiment.
By the way, another untapped market is outdoor day trips for frum women. If you can provide transportation, you can take a paying group to a park like Harriman or Bear Mountain (if you’re in the NYC area). There are trails of all abilites, and most can be done in under 3 hours.
(If all else fails, you can alway take them to Woodbury Commons. Nothing works you harder than hand-to-hand combat, and WC is the shopping bootcamp 🙂
