Besides having multiple national certifications, many of our trainers also have formal educations in exercise science. It is required of all Brooklyn Athletic Club Trainers to go through a 12 week in-house internship with our Master Trainers to learn our training methods. At Brooklyn Athletic Club, we pride ourselves in monthly continuing education so we can stay current and challenge our clients. Let our educated staff decipher between training truths and training trends.

All of our Trainers are available for Private and Semi-Private Sessions.
