Engine Builder Test

The Training Day Engine Builder Program is a 12-week program intended to improve your aerobic capacity by focusing on the three main monostructural metabolic conditioning exercises found in CrossFit: running, rowing & biking. Whether you choose to follow the program as-is or you modify it to your current abilities, you’ll still come out with an undeniably better ‘engine’ at the end of the 12 weeks than when you started. The volume of this 12-week program is pretty high. However, don’t let that intimidate you. Whether you choose to follow the program as-is or you modify it to your current abilities (I'll show you exactly how to modify the volume), you’ll still come out with an undeniably better ‘engine’ at the end of the 12 weeks than when you started.
