The control panel on one of the new environmentally friendly treadmills featured at the north and southside fitness centers tracks the energy the user generates which is transferred back into the power grid. These treadmills are a part of a vision led by Master Sgt. Joseph McTaggart, noncommissioned officer in charge of Ramstein Air Base Southside Fitness Center, who plans to make both fitness centers more environmentally friendly.
