Your core is the launch pad for every athletic movement. A strong core allows for a strong cyclist. The RealRides Strength Indoor Trainer DVD offers an 8-week training program specifically targeted to building a more powerful cycling core. In this program, Robbie Ventura, former professional cyclist 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, stronger core.
