I am now in my 50s and have been working in the fitness industry for over 30 years. In the 1980s, baby boomer women would pour into my then very popular exercise studio, right after work at 5 pm, and do an hour or more of group exercise classes to help burn body fat and look slim, trim and attractive. Guys were totally into the weight lifting scene at the time, pumping big iron in the various gyms around the Capital District.
Fast-forward to now and both genders participate in hot yoga and Soul Cycle/spinning programs (at all hours of the day) and are into Cross Fit and T25 and related functional training DVD programs. Everything old is new again but the newer generations are doing a better job of mixing aerobic, strength and flexibility activities than we boomers did. Generally, baby boomer women focused on aerobic type exercise in our 20s through 50s and men focused on muscle development and strength. As we age, we need to reverse our focus.
