Need a pre or post present-frenzy spin try this:
10 minute warm-up followed by 10 x 2 minutes (:30 right leg, :30 left, :30 both legs w/cadence at 110+, :30 relaxed). Follow these single pedal drills with 10 minutes at a cadence of 105+ and then cool down for 5 – 10 minutes. This is a good workout for early mornings, especially if you want to throw in a second, harder workout later in the day.
Happy Holidays, mb
