BILL GREEN's extraordinary career comes full circle at Wachusett Fitness, where he is a Johnny G-certified studio cycling instructor.  He attended the University of Delaware on a football scholarship with the expectation of becoming a coach, and after a 37-year detour as a professor at Holy Cross, Dr. Green has returned to coaching, with Wachusett Fitness studio cyclists as his team.  An author of two books on British imperial and European history, and an avid outdoor cyclist who has ridden throughout Europe, Bill uses classical music to flavor a session that is as mentally stimulating as it is physically challenging.

Bill leads a Studio Cycling: Easy Rider program on Mondays at 6 p.m., Studio Cycling: Lean Rider on Wednesdays at 6 a.m., and a 90-minute Studio Cycling: X-Country Rider on Sundays at 8:15 a.m.

Easy Rider: A lower intensity ride using light to moderate resistance and cadence, Easy Rider is designed for recovery from a tough workout, or to conserve energy for higher intensity workouts later in the week.

Lean Rider: A fat-burning, metabolism-boosting calorie blast, using moderate resistance and quicker cadence. Lean Rider is designed to increase energy while working in the ideal fat-burning zone.

X-Country Rider: A challenging physical pursuit to optimal fitness. Cross Country Rider spans several intensity zones, using various resistances, cadences and recovery intervals to enhance cardiovascular fitness.
