<p>Spinning – Indoor Cycling – is a form of exercise using a stationary exercise bicycle in a classroom setting. The concept was created in the 1980’s by ultra-endurance athlete Jonathan Goldberg. Participants set goals based on their perceived rate of exertion or heart rate using a heart rate monitor.</p>
<p>A typical class involves a single instructor at the front of the class who leads the participants in a number of different types of cycling. The routines are designed to simulate terrain and situations encountered on actual bicycle rides including hill climbs, sprints and interval training.</p>
<p>Each person in the class can choose his or her own goals for the session. Some participants choose to maintain a moderate aerobic intensity level, while others drive their heart rates higher in intervals of anaerobic activity.</p>
