Fitness Standards

The Initial Strength Test (IST) and the Marine Corps Physical Fitness Test (PFT) are official evaluations.

They are not practice events. They are not participation-based.

They are standards. Standards that show an individual has the potential to begin training towards being counted among the most elite warriors in the world.

The IST is conducted at recruit training. It confirms that a new recruit can do the minimal physical activity to safely begin training. The PFT is the formal, scored fitness test completed multiple times during recruit training and again on an annual basis after earning the title of Marine. It ensures Marines have what it takes physically to be elite warriors. Passing the IST qualifies you to start training. Passing the PFT is a requirement to graduate boot camp.

That’s why effort is not enough. Attitude is not scored. Repetitions must meet proper form. And performance is measured.

The Marine Corps fitness tests evaluate baseline readiness, including:

• Muscular endurance
• Muscular strength
• Cardiovascular endurance

The IST includes pull-ups or push-ups, plank, and a timed 1.5-mile run. The PFT includes pull-ups or push-ups, plank, and a timed 3-mile run.

Because Marines operate in demanding environments—carrying gear, moving under load, maintaining stability, and sustaining effort over distance—they need the type of strength measured by these tests. That is why physical fitness is a non-negotiable foundation for Marine training.

To meet the standard, you must be physically capable. For the IST, conditioning is each poolee's responsibility before arrival at the recruit depot. For the PFT, you can build upon your foundation from the IST to demonstrate proficiency in each event.

Before you enter recruit training, there will be opportunities to prepare for the IST with others through Delayed Entry Program (DEP) functions, and structured group workouts through the Squad Bay app. Take advantage of these opportunities, because they help you keep your preparation deliberate and consistent.

Arriving unprepared increases your chance of injury and creates physical difficulty that extra effort during the test will not be able to overcome. Motivation is essential, but it does not replace conditioning.

So, prepare early. Train correctly. And train to standard.

To execute required physical tasks to standard, especially when fatigued, also requires the right mental approach.

You will need an attitude that allows you to respond to commands correctly when you’re under stress, maintain proper form even when you’re tired, and continue to perform despite the discomfort you feel. In short, your attitude and mental toughness matter too.

Of course, you can’t think your way past a lack of preparation. You can, however, train your mind to support disciplined execution. You can also take time to learn the standard, practice the standard, and hold yourself accountable.

The IST and PFT have clear, measurable requirements. If you intend to earn the title Marine, you need to prepare to meet them—without excuses.
