Your core is the launch pad for every athletic movement. A strong core allows for a strong cyclist. The Real Rides Strength Indoor Training DVD offers an 8 week training program specifically targeted to building a more powerful cycling core. In this program, Robbie Ventura, ex-US Postal Service pro and pro-coach, alternates core-specific on-the-bike power intervals with off-the-bike core fitness speed work. Each segment consists of warm-up movements designed to increase flexibility and strength, followed by a timed speed-work routine. It's the perfect tool to build a balanced and stronger cycling core.
