I love Pt's that throw around the BS in Exercise Science degree.
Your better Pt's will have more time under there belt, learning someone limitations is the hardest thing to judge. People sometimes think they have been pushed to hard because they are sore for 2 days follwing a session. I did it part time for about 2.5 years....
I start tomorow actually again Part time again for some extra cash. The manager of the gym has been practically BEGGING me too, all of the Pt's at this gym look like the belong making biscuits at Hardee's.....
I don't use Bosu balls and do core type training, this crap IMO is for the yuppies, lift some damn weights if you want muscle.
Certification's vary from club to club...
Most all clubs will take the follwing:
ISSA
ACE
ISMA
IFA
You can get an ACE Certification in 2 days and for about 300 bucks.
