20. Reebok SXT
Not to be outdone by their competitors in Oregon, Reebok jumped strong into the training game in the late '80s. They came out with multiple trainers for multiple purposes - strength, court, and running - but it was the high and mighty SXT that ruled the day. The best part was, even for non-strength trainers, the SXT made it LOOK like you lifted while baggy Champion sweats hid the true evidence.
