Knowing when to train and how much time to devote to training each of the three energy systems is an important ingredient of success in endurance sports. This knowledge is also reflected in a well-designed and scientifically-based training plan.

The “priority training system” is one method first responders can use to ensure adequate exercise while not overexerting to the point that they are too fatigued to perform their jobs.

The National Strength and Conditioning Association (NSCA) is proud to announce the recipients of the organization’s 2025 Tactical Awards.

Contrary to popular belief, you do not need to “pump iron” to build muscle.
