Single-leg Press is our bread and butter. Different foot and hip positions for different phases of pedal stroke, standing, seated, etc. I use high speed video to match joint angles and velocities for each rider. We mainly do it ballistically for power - throw the sled as far as you can – at different percentages of max to match up to different muscle contraction velocities for different phases of the acceleration (different cadences). We do a lot of single-leg plyos on boxes, stairs, bunjee sleds, etc during speed phases. Strength and power gains are extremely specific and do not necessarily transfer well. When Ryan Bayley beat Sean Eadie in the Commonwealth Games sprint final in 2002, Sean was tripling 250kg for a parallel back squat and Ryan was tripling 120kg. On single-leg press, they were much closer (20kg) and so was the racing.
