Pros
At my location, I was able to work with people my own age which had the potential to be a lot of fun. I also think assisted stretching is super beneficial, so it was rewarding to help people.
Cons
If you graduated from college in an exercise related field, chances are you have already heard about facilitated stretching. Facilitated stretching and the PNF technique were not invented by StretchLab. StretchLab tries to make it sound like they have a monopoly on this "confidential" technique; however, this is dishonest. Upon working with them, you sign a non-compete agreement stating that you won't do assisted stretching anywhere else but StretchLab. I am a personal trainer, so legally, I signed away my rights to help my clients in stretching. Also, upon quitting, I was told that I could not practice assisted stretching in two counties near me for 18 months. After consulting with a lawyer, I was happy to hear that their contract was not lawful and therefore could not bind me to that contract, but it's something you should be aware of before signing. I only worked at StretchLab for 2 weeks before quitting and now I do facilitated stretching on my own as a personal trainer and I have made more in 1 week than I did in 2 working for them. StretchLab advertises to find "exercise science graduates" and "personal trainers" just to teach you something you've probably already learned about. Then they make it illegal for you to practice this "special" information. They really are trying to exploit younger adults who want to help people and who have the education. I highly recommend teaching yourself and offering stretching services as an independent contractor -- you make more money and you don't have to work under the thumb of dishonest, exploitative people.
