Bicycling Maximum Overload for Cyclists discusses a radical strength-based training program aimed at increasing cycling speed, athletic longevity, and overall health in half the training time. Rather than improving endurance by riding longer distance, this book will teach you how to do it by reducing your riding time and adding heavy strength and power training.

The Sirens & Titans Fitness Weight Loss Program

  • S&T Fitness addresses weight loss by educating clients on how weight is gained and lost, and then coaching the participant weekly on changes they need to make to reach optimal body weight and energy levels. 

  • Clients learn how they individually metabolize food,a key component to successful weight loss and sustainability. 

  • Clients are also exposed to the problems that semi-starvation and restrictive diets present.

  • The S&TF weight loss program is not a diet!  Weight loss is addressed from the most recent research on the science of weight loss and eating. 

  • Armed with this understanding, you will be able to make rapid changes in your body and health.  It will surprise you that there is a sustainable way to eat healthy, not be hungry, and lose or easily maintain your weight.

Alfonso Avalos Jr.
Strength & Conditioning Coach

Being a competitive power-lifter, I have always sought different perspectives and beliefs in programming for competition. This led me down the rabbit hole of movement, speed, agility, periodization and injury prevention. My insulated world opened to new possibilities for not only training myself, but for competitive athletes, kids, seniors and their respective sports beyond that of what I know: squat, bench press, and deadlift. I continued my pursuit by volunteering with the San Jose Sharks during their Rookie Development Camps.

Alfonso is a  Certified Strength and Conditioning Specialist through the NSCA.
