Certifications accepted by both 24 Hour Fitness and Club One
I've been considering becoming certified and learned that if you want to work at a major gym, these are the only certifications accepted by both 24 Hour Fitness and Club One (though Club one also expects you to have a 4 year degree or a 2 year certification from a college in a related field) Each Gym accepts some others but if you want one certification which gives you the best chances for employment, these are the only four accepted by both chains.
