Here&#x27;s a video showing interval training on an exercise bike <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=LeEHYdFhK4o&amp;list=PL2Y4NA_zw1s3NKkUv-Wy5QgKpK3q6f2TH&amp;index=1" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=LeEHYdFhK4o&amp;list=PL2Y4NA_zw1...</a><p>The way I&#x27;ve been doing it (I&#x27;m no expert), is after pedaling normally for a minute or two, I turn up the resistance and pedal all out for 30 seconds or so, then turn the resistance back down and pedal normally for a few minutes until my heart settles back down, then repeat a few times or so.  I go more by distance than time.  I try to pedal at least a mile, with high intensity bursts of at least a tenth of a mile or more. It will make you sweat and heart race if you are really going all out.
