Get stronger and faster on the bike by building endurance strength. This workout is key to build that strength you will need to ride off the front in a cycling race, or the strength needed to finish a 70.3 or Ironman bike leg without falling apart or getting tired legs so you can still run well. This workout is key to do every week or every other week to strengthen specific muscle fibers so you can ride longer and without fading in those long rides, climbs and grand fondos.
