Triathlon is an endurance sport, but endurance alone is not enough. To be fast, one also needs good training discipline, technique, movement economy, quality equipment, and of course, the right mental attitude. However, one component is still missing: strength. Targeted strength training is therefore essential for every ambitious triathlete—not just during the off-season! A strong core stabilizes the body and ensures that all your energy goes into movement. Strong tendons and ligaments are the prerequisite for an injury-free season. And strong arms and legs? Well, they ensure that you swim away from your competition in open water, outsmart them on the climbs, and finish the sprint with more than just a nose ahead. Use the exercises in this book to lay the foundation for a strong competition season.
