Job wise it'd be to work as a strength and conditioning coach at high school/college/private or professional level, injury rehab, personal training, or teaching (if you have relevant qualifications allowing it). There's more demand in the US than in the UK due to the amount of sport - UK is saturated now and jobs advertise wanting masters, several vocational qualifications and multiple years of experience to even be considered, and that's just for an unpaid internship !
Additionally as the US doesn't have the undergraduate version of the degree I'm doing, when applying for an entry level position I'm slightly ahead of the game with a specific degree and 7+ years of experience.

Not saying any of this necessarily helps me get a job out there, I still think continuing education is my best bet (bar marriage).
Fortunately the industry places a big emphasis on experience (and having good contacts), therefore a fresh graduate would be in a worse position than I'd be if I went and did another degree now.

To teach anything in the public school system, in any state, you will have to have a recognized degree, and a teaching credential in that state ( typically a certificate). Your degree doesn't exist in the USA (as you stated earlier) so I think you will run into a problem obtaining a teaching certificate without further education in which ever state you chose to live. You will need a Doctorate of Physical Therapy (PT) to enter the field as a "professional" Physical Therapist. As a side note, the field is quite saturated now, but as the US is a huge place, supply and demand varies across both state, county & city/town boundaries. The field of rehabilitation in the US has very specific degrees, without exception. Having said that, there are instances in some states where certain professional boundaries are being encroached upon by other disciplines; Athletic Trainers and Massage Therapists encroaching on PT, so it's not outside the realm of possibility to enter one of these fields with your background/experience, but again, I feel certain you will have to take further courses to obtain certification and/or licensure in your chosen state. Good luck with your plans!

Hmmm, there may not be a degree in the US with the exact same name as yours, but there are dozens of kinesiology programs in the US that include a considerable strength and conditioning component. From experience I'd say at least a third of kinesiology undergrads in the US are pursuing, or already in, a career in strength and conditioining.
